LED Grow Lights
There has been much recent controversy among cannabis growers about LED grow lights. Just a couple of years ago the thought of growing weed under LED lighting would have been laughable. However, recent advances in LED technology have led to more and more growers seeing success and LED lighting sources are fast growing in popularity. Like anything, improvements make leaps and bounds very quickly and these days LEDs are used in all kinds of lighting in your home, office and car including successful marijuana grows.
We are here to tell you that growing marijuana with LEDs works. The best models offer results better than HIDs together with huge electrical, management and heat savings. A number of our members in the HTG forum have shifted to growing under LED and are not going back to the old ways of burning electricity with HIDs.

Nearly all LED Grow Lights are produced in China even if they are designed in the USA. If nothing else the component are made in China. This is the broad concept though of the market.
Cheap – Poor spectrum, LEDs and build quality
UFO type LEDs from many online sources and of course eBay. They may quote all kinds of huge Watts or ‘full spectrum’ but when you see big red and big blue LEDs in a cheap looking plastic housing you know this is the bottom end of the market. You will not be getting top shelf LEDs and results / yield will be drastically affected. We just don’t recommend these products at all. You are far better off buying a HPS/MH system and deal with the added electricity costs and ventilation issues.
Mid price – Bands of spectrum, fans and reasonable quality
These usually look more the part with better housing, higher quality LEDs that may even include brands like Epistar and Bridgelux. In variably though these will not be full spectrum LED grow lights they will be 6, 8, 11 or 12 band models. These bands will cover sections (bands) of the whole PAR spectrum but will miss chunks here and there. The sun doesn’t miss any of the spectrum required to grow and flower plants correctly so why would your plants react to their full potential under them? They don’t. Mid price larger models will incorporate fans for cooling.
High end – Full spectrum, fan-less operation, excellent build quality
These are more often the full spectrum models that cover approximately 420 to 750 nanometres, the PAR range. They include expensive white LEDs and in photos you will see some LEDs look like they are ‘dead’ – not true these are emitting in the far-red portion of the spectrum which is 710 to 850 nanometres, dimly visible to some people eyes. Look for high end components such as brand name LEDs from Epistar, Bridgelux or Cree. Thermal engineering is a key to design with the best being fan-less. LED grow lights that are high Watt and fan-less are designed well because they have dissipated the heat created by the LEDs perfectly using rapid heat sink materials. Then there are self protecting power supplies, UV protected and angled TIR lenses and not to mention the warranty, two years is not enough. LED grow lights with these features offer excellent results with thick and juicy buds.
LEDs pros and cons
- LEDs have far lower energy consumption running at approximately 60% of an equivalent HID;
- There is no filament to burn so LEDs have longer bulb times of 50,000 to 60,000 hours versus HIDs which start dropping output considerable at 2,000 to 3,000 hours;
- LEDs are smaller and faster to emit light and are physically more robust so they relatively shock resistant being solid state components;
- LEDs’ offer far less heat output, in fact the good ones run pretty much ‘cold to touch’ while HIDs run very hot. LEDs reduce your fire risk considerably;
- LEDs can focus their light output with the use of lenses rather than disperse the light like HIDs that require reflectors;
- Precise current (power) management is required with LEDs when compared to HIDs. However, LEDs have the power management built in while the HID lamps rely on external ballasts which also add another 100 to 150 Watts of power consumption;
- LEDs are more expensive to start a grow with when compared to HID but they are cheaper over the long term;
- LEDs are instant on and instant off, they do not need to ‘warm up’ like HID lamps;
- LEDs can be dimmed also if required;
- LEDs are safe, classed as ‘Class 1 LED product’ as they do not contain mercury like compact fluorescents;
- LEDs powerful enough for lighting big areas like rooms or greenhouses require more precise current and heat management but are now used in some large areas over CFL and HID lighting.
Brief history of LEDs
How do they work? LED grow lights produce light by passing a current through a semiconductor material. The movement of electrons within the semiconductor releases energy in the form of photons, i.e. light.
LEDs once just came red in color, they were the little low lights in the corner of every TV. These days LEDs have advanced massively, they are now available across the spectrum from ultraviolet through the visible right into infrared wavelengths with very high light output.
The first observation of ‘electroluminescence’ was in 1907 by a British experimenter from Marconi Labs named H. J. Round. Then twenty years later, way back in 1927 a Russian named Oldeg Vladimirovich Losev created the first LED but no practical use for it was found. It took until 1955 for semiconductor alloys, namely gallium arsenide (GaAs), gallium antimonide (GaSb), indium phosphide (InP) and silicon-germanium (SiGe) to show infrared emissions at room temperature as firstly observed Rubin Braunstein working with RCA (Radio Corporation America) . Then in 1961 Texas Instruments patented the idea.
How are LED colors made?
The semiconductor material has a p-n junction which is the interface between the two types of semiconductor materials, n-type and p-type, known as ‘n’ and the ‘p’. This is the active site whereby the electronic action of the LED takes place. The color of the light emitted or its wavelength is dependent on the ‘band gap’ energy of the materials forming the p-n junction.
In 1962 -Nick Holonyak Jr., considered by some the father of LEDs, working within General Electric (GE) reported the first visible spectrum LED showing red color. Craford, then graduate student of Holonyak, created the first yellow LEDs and improved the overall brightness of his red and orange LEDs tenfold in 1972.
The Monsanto corporation, yes the seed guys who sued USA farmers, were the first to mass produce visible spectrum LEDs, firstly as indicators, in 1968.
We had the first high powered blue LED (not the first blue) created by Shuji Nakamura of the Nichia Corporation in 1994 which was based on the semiconductor alloy InGaN or Indium gallium nitrite, your new word for the day?
This quickly led to the development of the first white LED using Yttrium aluminium garnet or ‘YAG’, which is a phosphor coating to mix ‘down-converted’ yellow light with blue which produces a visible white light.
Moore’s law which saw the doubling of chip performance every 18 months to two years, applies similarly within the LED industry with a doubling in performance ever 36 months since the late 1960’s due to the improvements in semiconductor and optics.
Full spectrum LEDs vs. 3 band, 5 band, 11 band
As with many plant species, marijuana also has light-mediated development – photomorphogenesis. The blue spectrum stimulates vegetative growth and the yellows, ambers, reds and far-red spectrum stimulates pre-flowering and flowering (reproductive growth). Therefore, growing marijuana to maturity will use the light wavelengths from approximately 420 to 730 nanometres (nm), covering both chlorophyll A and chlorophyll B absorption peaks (Photosynthetically Active Radiation, or PAR for short).
LEDs are manufactured using different semiconductor materials to create LEDs which emit light of different wavelengths. Using LED grow lights that emit the proper spectrum is essential to obtaining high yields.
In the earlier days of LED grow light technology, your main options were red and blue diodes or more expensive white LEDs. The white LEDs, commonly called full spectrum LEDs, provided a much closer match to the natural spectrum of sunlight (the PAR spectrum) than the individual diodes which emitted light at a single wavelength.
As you can see from the table below, there are now many different possible LED diodes that can be produced using different semi-conductor materials.
What wavelength or spectrum your LED grow lights offer your marijuana is of paramount importance to your yield. The most expensive LEDs are white, offering a broad spectrum of light like the sun covering much of the visible light spectrum (PAR). You need white LEDs! If you see an LED grow light with just red and blue lights you are not going to achieve a high quality grow at all as the white LEDs are so much closer to mimicking the sun. The table below outlines the different LEDs versus the color and wavelength they produce.
Many leading LED producers now use an assortment of different diodes in place of white LEDs. These manufacturers state that by choosing individual diodes they can match the PAR spectrum more closely than a white led. White LED lights do have peaks and troughs in their spectrum, as do spectrums composed of individual band diodes. When choosing an LED grow light it is important to consider the spectrum it covers and how closely that spectrum matches the PAR spectrum.
The more closely the LED matches the PAR spectrum the more efficient it is. There is less light that cannot be used by the plants which means less waste. An efficient LED grow light saves on electricity and boosts yields. In addition, less light is lost to heat, which decreases the cooling requirements in the growroom.
How to make high intensity white LEDs (WLEDs)
- Use a single LED that emits three primary colors of red, green and blue and mix the colors perfectly to form a white light. These are known as ‘multi-color white LEDs’ or ‘RGB LEDs’ and are more complex to manufacture than the phosphorus type explained below. Multi-color LEDs are at the forefront of LED development because with the right tweaking they can offer nearly any color light we want by mixing primary colors. These are the best type of white LEDs;
- Or use a phosphor based semiconductor material to convert a blue or even a UV light into the broad or full spectrum white light your plants require. These WLEDs are known as phosphors based white LEDs which are also the easiest to manufacture and therefore the cheapest to buy;
- There is a third method of making white LED grow lights using zinc selenide (ZnSE) but this is in its early stages.
The key difference between WLEDs is how solid their color stability, color rendering and luminous efficiency are key. Color rendering index, CRI, basically means how faithfully the color is produced, you may know the term from using Photoshop. While luminous efficiency is discussed later on. If your LED grow light is constructed using LEDs from brand name suppliers such as Cree or Bridgelux, then these issues will be minimized and cause little affect. It is far easier to get good solid color rendering and luminous efficiency with the multi-color or RGB white LEDs.
- There are many commercially available LED units that have spectra specifically balanced LEDs for the grow room. This is generally achieved by using a mix of red and blue then white, ambers and far-red ranges so that they cover the entire spectrum;
- When you see LED grow lights advertized as 3, 5, 6, 11 or 12 band LEDs this means they offer a spectrum with gaps, maybe something like this: 440nm, 470nm, 525nm, 640nm, 660nm, 740nm. So there will be peaks and troughs in the spectrum produced rather than one continuous full or broad spectrum. These ‘6, 11, 12 etc band’ products operate in some but not all of the spectrum required for a successful, fast, big yield crop. These are not full spectrum grow lights;
- Quite often LED grow light companies are reselling someone else’s product configuration and they simply don’t know what LEDs are mounted in the system;
Did you know that LEDs are now available is very short wavelengths with near UV 375-395 nanometres and more expensive models that achieve wavelengths closer to 240 nm. The absolute wavelength depths of LEDs are known as ‘deep UV’ with labs using diamond to produce 235 nm, boron nitride at 215 and aluminium nitride right down at 210 nm.
LED efficiency versus HID lamps
LEDs are ‘luminous efficient’, which means they produce visible light very efficiently from electricity. For example in 2002 Lumileds manufactured a 5W LED with a luminous efficacy of 18 – 22 lumens per Watt, compare that to the traditional incandescent bulb which at around 80 Watts offers 15 lumens per Watt (lm/Watt). Nichia released a white LED 140 lm/W in 2010. Since then Cree have increased that right up to 254 lumens per Watt at a color temperature of 4,408 K (Kelvin) using the Cree XLamp® which uses silicon carbide technology and runs at 350 mA. Note these figures are in controlled labs and are only the chip, so in real life after the LED has its plastic shell and is mounted these figures will be much lower but they are still better than the HPS lamps with standard HPS lamps running at approximately 100 lm/Watt.
These days, good LED grow lights will save a grower around 50% off their electrical bills. Growing with 2 x 250W (true Watts drawn not potential draw) equals a total power bill of 500 Watts per hour. This setup will offer better but comparable growing to a 1000 Watt HID (HPS or MH) which also requires a 150 Watt ballast. So when you include the ballast and potential ventilation system the savings are more like 60% or more.
High powered LEDs (HPLEDs) – 1W, 2W, 3W & 5W
Normal LEDs used in electronics consume a tiny 30-60 milliwatts (mW) of power at very low amperage; note the word ‘milli’ in there. However high power LEDs running at between 500 milliwatts to over 500 Watts (Yes! Think industrial lighting) are driven from 100’s of mA (milliamps) to over an Ampere. In 1993 the first highly bright blue LEDs were manufactured by the Nichia company and were based on silicon carbide. It wasn’t until 1999 that Philips Lumileds introduced the first 1 Watt LEDs to the market in far larger semiconductor die sizes.
So what is the difference between 1Watt and 3Watt LEDs then?
The 1W and the 3W can tolerate running at a range of power outputs up to and over there named Wattage. So a 3W LED can run at say 1W but it will also be able to run at say 4W too. Why? Well it’s because the names given to these LEDs (1W, 3W, 5W) are only ever a guide as to the power possibilities of the LED. However a 3W LED is built on a larger semiconductor die size when compared to a 1W LED so it is built to run at higher Watts, this why it is named a 3Watt LED.
IMPORTANT – Advertized Watts vs. actual Watts draw.
All LED grow lights run well below their potential Watts. If you have 100 X 3W LEDs the potential is 300 Watts but the actual draw will be closer to 150 Watts. LEDs are usually driven at anything from between 50% to 65% of their potential. If you run a 1 Watt at 1Watt continuously or a 3W at 3Watt you have a greater chance of color shift and will also cut its life (hours) down considerably, just as you would running a car at high revs all the time.
Let’s get this straight; don’t be fooled into thinking that just because your LED grow light has 150 x 1W LEDs it as an output of 150 Watts. No, it does not. Well, you hope it doesn’t as the bulb time will be severely limited if you power it at full capacity at all times. Your LED grow light will have an output closer to 55% to 65% of its full capacity; the same concept applies to all LED grow light diodes.
Again, if you see a light advertised as 450 Watts using 150 x 3W LEDs its actual draw will be more like 250 Watts. You can work out the actual output or draw of any LED grow light using the Volts, Amps Watts calculator. If the company selling the lights does not advertise the Volts and Amps then you have to wonder why and assume they are run at 60% of capacity. We have compared a couple of popular LED grow light models further down this page on their actual draw versus their advertised.
Heat – Thermal management of LED grow lights
Another happy result of LEDs having no filament is that they are far more efficient than other light sources and LEDs produce far less heat. With traditional HID’s, up to 95% of energy is wasted as heat or radiation, whereas LEDs run relatively cool they do still produce some heat. That heat difference means HIDs should be placed two or three feet above the plant canopy while LEDs can be placed extremely close, usually around 12-18 inches, helping prevent ‘stretch’ and directing the light exactly where it’s needed.
Even though LEDs are far more energy efficient and waste a lot less heat than HIDs there are still heat issues associated when running high powered LEDs. LEDs are cool to touch mainly because they do not produce heat in the form of infrared (IR) radiation. The higher the Watts the less energy efficient they become because they turn more and more electricity into heat which is wasteful and needs management.
Where does the heat come from? The heat originates at the semiconductors p-n junction due to its slight inefficiencies when electrical activity is not turned into light. The p–n junction in turn heats the soldering point and that heats the metal core printed circuit board (MCPCB) which then needs to be directed into a heat sink so it dissipates into the atmosphere.
The three areas focused on for heat transfer are convection; which uses a moving fluid such as water or air to cool the device, conduction; whereby heat is transferred from one solid to another until there is no more and the last is radiation but that isn’t used with LEDs.
The best LEDs use heat sinks to control heat. The heat sink medium provides a path from the LED to the medium which dissipates the heat. If you are using a smaller LED light (under 700 Watts) look for a model that uses passive cooling through heat sinks. The best thermal management within high powered LEDs uses heat sinks that include materials such as aluminium, copper, thermoplastics and at the high end of the cost scale, graphite. The heat sink material needs to incorporate a large enough surface area to work so this is why you see the classic ‘fins’ shape layered next to each other to the top of some high end LED grow lights.
Because properly designed heat sinks require a large surface area, they are not always the most practical way of cooling large LED grow lights. Some high quality larger lights use a combination of passive heat sinks and fans to efficiently cool their lights. However it is possible to have a fan-less system which if designed well with big fin like heat sinks is optimum as it removes the chance of fans breaking and airflow being required.
Thermal management of LEDs is a science in itself. There are a variety of methods, each with its own benefits and drawbacks. Fans add extra moving parts to your system and have the potential to break down if they are poorly made. Choose fans that are rated for a lifetime that exceeds that of the LEDs. Passive cooling systems require airflow and many cannot be mounted to a ceiling. Larger Wattage LEDs that use only passive heat sinks are not always fully cooled. Poorly cooled LEDs degrade quickly from excess heat. Look for a well-built LED grow light that uses high quality components regardless of the cooling technique.
LED grow light lens – Boost light & direction
LEDs only look like their finished product when the ‘die’ or ‘chip’ is set or encapsulated in a resin or plastic which is known as potting. This plastic shell helps out in many ways. It holds the very delicate system together, mounting the LED is made far easier in products and it acts as a lens or refractive intermediary to boost the light from the semiconductor. As you can imagine there are a lot of different methods of potting these chips to make LEDs – some cheap and some expensive which result in different light output.
Light extraction of grow light LEDs is just as important as the semiconductor materials being used. Most materials have very high refractive indices so that light is reflected back and out of the LED.
- There are many types of lenses and reflectors available to harness the LED’s output and direct it where it will do the grower the most good. A simple, well-designed reflector is usually suitable to do the job, but Total Internal Reflective (TIR) lenses more fully and accurately collect and guide the light;
- Make sure you choose a reflector or lens product with an output that meets your needs. An LED’s light output is usually a cone with a 160 degree angle. Some products have 120 degree lenses but we find a LED lens with an angle of 90 degrees is just about perfect at directing light deep into the plants. However, too wide a lens spreads the luminous intensity over too great an area, it wastes light, either providing too little power to your plants, too wide a coverage area or both. Some LED grow lights have no lenses and obviously, these are a waste of valuable light, and your money;
- Narrowing the lens or reflector increases the power delivered to your plants significantly, up to 400-500%, but narrows the effective coverage area. A good trade-off for both problems is to use a medium output angle, from 60-90 degrees. The grow light manufacturer should provide effective coverage charts for their products and some will even perform photometry evaluations for your specific grow area, telling you exactly where to place your light(s) for maximum effect.
Best LED Grow Lights for 2016
LED grow light technology is rapidly improving. Unfortunately, there are still a lot of cheaply built lights out there, and even more misinformation being circulated. Before we share our reviews of the best LED grow lights of 2016, we want to set a few things straight:
Most LEDs are not named based on their actual Watts, which leads to confusion. If you purchase an 800W LED its actual Watts are will be around 450 or 500. It is a replacement for a 600W HID, but not for an 800W HID.
What this means for you:
When replacing an HID with an LED, choose the size of the light based on actual Watts. Remember that an LED is more efficient and will replace an HID with higher actual Watts. Currently the only LED grow lights being named for their actual Watts are those from Black Dog.
Efficiency and Spectrum
LED grow lights are becoming more and more efficient. They can do this in two ways:
- 1. Intensity of Light: Measured by a PAR meter.
- 2. Accuracy of Spectrum: The PAR curve shows the wavelengths of light that a plant can use. Any light which hits a plant that is not in these wavelengths is reflected. This reflected light = wasted energy in any LED grow light.
What this means for you:
The spectrum of an LED grow light should match the PAR spectrum as closely as possible for maximum efficiency.
Some manufacturers offer graphs to help you see how their spectrum matches the wavelengths plants use, like this one from Platinum LED. The three lines show the absorption peaks for chlorophyll A, chlorophyll B and carotenoids. The colored peaks show the spectrum that Platinum LED’s lights use. As you can see, they’ve tried to match the absorption peaks for photosynthesis so no light energy is wasted.
PPFD and Footprint
The terms Photosynthetic Photon Flux (PPF) and Photosynthetic Proton Flux Distribution (PPFD) are being tossed around a lot in the LED grow light world.
They are measurements that help you decide how much PAR spectrum light is reaching your plants. But they are only part of the story.
PPF: This number is pretty useless. It tells you how many PAR spectrum photons are leaving the light, but don’t tell you anything about how much of that light reaches the plants.
PPFD: a measure of the number of photons in the 400-700 range (PAR spectrum) that fall on a square meter of target area per second. Measured in µmoles/m2/s.
- Why it’s useful:
This number can help you compare the amount of photosynthetically available light that is emitted by different LED grow lights
- Why it’s usefulness is limited:
PPFD is typically measured in the center of the light, 12” below it. What’s wrong with that?
- You normally place an LED about 30” above your plants, so a reading at 12” isn’t really relevant.
- You are growing in a broad space, say 3’ X 3’ or 5’ X 5’. It is important that PAR spectrum light reaches all areas of the grow, not just the center.
PPFD is useful, but it doesn’t tell the whole story. If you just compare PPFD values, you may end up purchasing an inferior light.
What’s Better than PPFD?
When investigating a grow light you want to consider the entire footprint; the larger the footprint, the greater the area that receives considerable amounts of PAR spectrum light.
Some manufacturers provide graphs showing the change in the amount of light reaching the plant throughout the footprint of the light, like this great image from California Light Works.
As you consider each of the lights on our Top 10 LED Grow Lights for 2016 list, keep in mind that any single piece of information we’ve provided is only part of the story. We’ve given you the best information available. It is up to you to put the pieces together and choose the light that is best suited to the size and style of your grow.

2016 LED Grow Light Review
#1: Black Dog
Model: Phytomax 800 LED Grow Lights
Black Dog is trying to set the record straight about LED grow lights. They have started by naming all their lights accurately based on their actual Watts.
“We focus on true footprints and true results. Part of our challenge is to educate people. Everything is based on research and trials. There is a lot of misinformation being spread out there which we are trying to fight our way through.” Patrick at Black Dog
They strive for transparency, which starts with disclosure of the actual Watts and carries all the way through to their stellar warranty, which is the best available.
At 800 Actual Watts, their Phytomax 800 is a true replacement for 1000W HID lights. In fact, it kicks any 1000W HID light’s a$$.
Actual Draw in Watts
The Phytomax 800 is one of few LEDs named for its actual Watts instead of its LED Watts. The actual draw is 800 Watts, with an LED Wattage of 1710W.
There are 342 high output 5 Watt LEDs. They have LEDs from five top manufacturers, because no single manufacturer makes diodes covering the entire PAR spectrum and UV and IR light.
Grow Light Spectrum
Black Dog LED’s proprietary full-cycle Phyto-Genesis Spectrum™ is full spectrum without gaps between 375 nm and 735 nm.
The spectrum spikes to match the PAR spectrum as closely as possible.
It covers UV light which increases THC and CBD content, boosts terpenes and flavonoids for better taste and boosts antioxidants, vitamins and pigmentation of buds.
The spectrum also includes near infrared (NIR) light to boost photosynthetic activity.
Black Dog uses one of the most effective active heat management set-ups in the LED industry, with ultra-quiet, durable fans to maximize the life of your light.
The Phytomax 800 has a 120° beam angle primary lens.
At Black Dog they don’t use secondary lenses, because these actually reduce efficiency. You lose about 2% of your light intensity just by filtering it. While a secondary lens may look nice in the stats, it actually decreases the footprint of the grow light.
Peak Photon Delivery in µmoles
Black Dog made it clear that PPFD is only one aspect of measuring a grow light’s efficiency. As we mentioned above, alone it doesn’t tell you how well a grow light actually grows marijuana plants.
Black Dog is the only company that gives footprint information specifically for growing marijuana.
They have had the footprint of their lights independently tested with light spectrometers. These tests have shown that they have large, even footprints with no hotspots.
For growing cannabis, use the following recommendations:
- Vegetative Stage: 7’ X 7’ with light hung 40 inches above plants
- Flowering Stage: 5’ X 5’ with light hung 29 inches above plants
If you ever decide to grow something else under these lights (hey, you may decide you want hydroponic tomatoes this winter!) check out their guidelines for different footprints here. It also discusses adjustments for growing auto-flowering varieties.
Build Quality and Materials
The Phytomax 800W LED grow light is built with commercial grade components designed for a long life. It’s industrial heat sink is the largest in the industry.
- 21” X 21” X 7”
- Weight: 50 lbs
- Expected Lifetime: 50,000 hours
Black Dog offers the best warranty available for LED grow lights. It is a limited lifetime warranty which features:
- 90 day money-back guarantee
- First 3 years: all parts, all labor. You’re covered no matter what happens.
- 3-5 years: all parts are covered.
- 5 years+: call Black Dog for trouble shooting and support.
As Patrick from Black Dog explained, five years is a lifetime when it comes to technology. Most clients want to upgrade to the latest LED grow light before then, and Black Dog has you covered there too.
They offer upgrade programs depending on how long you’ve owned a light. This means significant amounts of credit when you upgrade to a new LED grow light.
Here’s what growers are saying about the Phytomax 800W Grow Light:
“This is the best light out.” Review from youtube.com
“With this update, only two companies- Black Dog LED and Build My LED- were put in the ‘Good Choice’ column. Black Dog LED has UV, IR and isn’t exaggerating footprint sizes or lying about anything.” Review from www.compareledgrowlights.com, which aggressively picks apart the claims made by the leading LED producers.
“You can’t do this with other LED Grow Lights — #PhytoMAX800—Larger Yield, Higher THC 2-5%, Lower Power.” Review from Instagram.com
#2: California Light Works
Model: Solar Storm 440W
California Light Works (CLW) is the oldest LED grow light company in the industry. They credit their success to the ingenuity of electrical engineer George Mekhtarian, who is the owner/operator of CLW.
Mekhtarian’s genius is evident in the Solar Storm 440. This highly scalable full spectrum LED grow light is up to 25% more efficient than competitors. It features UVB supplementation to inhibit mold and mildew while increasing potency. The mode settings make it easy to switch back and forth from vegging to flowering spectrums.
This is an efficient, reliable and well-designed LED grow light from a very dependable company. Let CLW make your next grow the best you’ve had yet.
Actual Draw in Watts
The actual draw of the Solar Storm 440 depends on which mode you’re using:
- Veg Mode: 235W
- Flowering (Bloom) Mode: 320W
- Bloom Mode + UVB T8 bulbs on: 350W
This grow light has 144 3W Osram SSL LEDs. This gives them 1.7 mmol/j efficiency, which is 25% higher than competitors.
Grow Light Spectrum
CLW uses their proprietary OptiGrow® Blend which is based on university studies. It features dominant wavelengths at:
- 440 nm (Deep Blue)
- 470 nm (Blue)
- 620 nm (Red)
- 665 nm (Deep Red)
- 3100 K (Warm White)
- 285-315 nm (UVB)
There is a switchable feature which allows you to turn the UVB light on and off as you choose. UVB exposure will increase yields and reduce the risk of bud rot. Unless mold is a serious issue in your grow room, you do not need to leave the UVB light on at all times and can turn it off to save energy.
This unit stays cool using 92mm integrated fans and large heat sinks.
The Solar Storm 440W light will cover:
- Vegging (up to 5’ about plants): 36 square feet (6’ X 6’)
- Flowering (16”-24” above plants): 9 square feet (3’ X 3’)

#3: Dorm Grow
Model: G8LED 450W Veg/Flower and G8LED 900W Veg/Flower
Dorm Grow’s G8LED grow lights are among the most efficient on the market today. They have a sound reputation for producing high quality lights that last.
Unlike HID lights which throw off light in many wavelengths that plants can’t use, the G8LEDs use the Optimal 8-band spectrum to deliver light in exactly the right wavelengths for plants. This means no wasted light. For you that means a lower electric bill, higher yields and a better final product.
They include UV and IR light, which not only improve photosynthesis but also fight mold and boost the terpene content of your buds.
Dorm Grow stands by their lights because they know they have a quality product. As Robert from Dorm Grow explained,
“G8LED Technology provides the most efficient photosynthesis from a grow light using the Optimal 8-band wavelength spectrum. From seedling to harvest, the G8LED system gives some of the best yields possible from any LED grow light system.”
He’s confident that you’ll love these lights, and so are we.

“G8LED 900W grow light and two G8LED 90W Red UFOs – that is all you need. Hands down best growing system for the money (actually saves me money!)” Review from theweedblog.com
“G8LED 450 Watt LED Grow Light is a very high quality,durable and outrageously bright.i did a ton of research on all led specs,parts,brightness and reasonably priced,and this light exceeded my expectations and now im walkin’/basking in sunshine B-)” Review from amazon.com
“The G8 system is a cut above the rest. Very few led systems are able to match the yield of sodium lights but G8 has done it. Using their system I used the 450 and added the 90red after my dark period and I outperformed my 600w sodium light on my first try. I had already done extensive research and knew the G8 technology was the real McCoy but having the results in my hands was truly a rewarding experience. Indoor growers Can’t go wrong with this system.” Review from amazon.com

Model: Advanced Platinum Series P300W
Platinum LED is another company that is striving for transparency and quality. We think they’ve achieved both. Their LED grow lights are made in America, so you’re dollars will stay right here, helping to build the economy.
Platinum LED proudly told us:
“We’re producing the most powerful LED light on the market. We have the highest PAR for the Watt of any grow light right now. That means we have the brightest lights.”
Even more important than having bright lights is having light in the right spectrum. Platinum LED uses 12 different colors of narrow banded diodes to match the natural absorption curve as closely as possible.
Actual Draw in Watts
The actual draw of this grow light depends on which setting you use:
- Vegging: 93 Watts
- Flowering (Veg + Bloom Switch): 180 Watts
100 U.S. Made 3 Watt LEDs

“Never… ever have you seen growth like this. Platinum LED lights are the highest powered, best spectrum emitting lights you can possibly find on the market today and the results don’t lie! Using only 2 of these P450 lights in a 4×4 tent, I regularly pull over 1.6 grams/watt while using less than 600w of power.” Review from Amazon.com
“I was very skeptical, I called the manufacture and asked them an array of questions. Great down to earth people who know what you’re doing and want you to be successful. This is honestly one of the best purchases I’ve ever made.” Review from Amazon.com
#5: Super Grow LED
Super Grow LED is one of the few grow light manufacturers that offers a true continuous full spectrum, with no gaps. Their SK450 is an industrial grade grow light designed for maximum efficiency.
This light is ideal for use from seed to harvest. It will maximize growth during all stages, improve your cloning success rate and boost yields. With their tough fanless design these grow lights are built to last.
The SK450 comes with clear instructions, specs and diagrams showing a variety of potential grow room set-ups. If you have any questions Super Grow LED’s in-house lighting engineers are happy to help at any time. These durable lights will improve the harvest from a grow of any size.
Actual Draw in Watts
The actual draw of the SK450 is 252 Watts.
Super Grow LED uses Bridgelux and Epistar chips in their own custom diodes. They use a phosphor coat on a high power 425 nm blue base LED to create strong, continuous full spectrum coverage.
The SK450 has 150 3W LEDs. These give 250 Watts of true power, and are a real replacement for a 450W HID grow light.
Grow Light Spectrum
This is one of the few LED grow lights out there that really does provide continuous full spectrum light. The SK450 is continuous full spectrum from 420-750nm, with supplemental cholophyll absorption peaks. Their spectrum closely matches the natural spectrum or daylight.
Two thirds of the diodes in the SK450 are “white” LEDs, which have a mix of red, green and blue light. These supply the full spectrum. The remaining third of the diodes are a mixture of red light wavelengths to supercharge the flowering cycle. This increases yields and allows strict photoperiod control.
This image shows the SK450 (aka the Spectrum King) compared to HID lights and the PAR spectrum (the McCree Curve).
This fanless LED grow light uses high quality heat sinks, thermal bond and metal clad printed circuit boards to manage heat.
There is no heat increase 12 inches from the source, which will considerably reduce HVAC requirements in your grow room.
The coverage of the SK450 depends on the growing stage;
- Vegetative: 30 square feet
- Flowering: 16 square feet
Two or more SK450 units can be easily bolted together to cover larger grows.
|Qty.||LED||HID equiv.||Flower||Pro. Yield|
|1||250W||500W||16 sq ft||300g|
|2||500W||1,000W||16 sq ft||600g|
|3||750W||1,500W||24 sq ft||900g|
|4||1,000W||2,000W||32 sq ft||1,200g|
The SK450 features 90° lenses for optimal photo deliver. These lenses are the best compromise for maximizing the coverage area while maintaining a high light intensity. This give the SK450 the best value in terms of cost per square foot of harvest area compared to LED grow lights of the same size.
Peak Photon Delivery in µmoles
Par Output: 1000 µmoles at 12” from center
Build Quality and Materials
These LED grow lights are built with rugged materials like the anodized aluminum chassis. There are no bulbs or ballasts to replace.
- Dimensions: 22” X 14” X 7”
- Weight: 23 lbs

The SK450 comes with a 5 Year Warranty from manufacturer’s defects.
Their customer service is outstanding. You’ll have access to their in-house engineers in case any questions or problems arise.
People love the SK450 for its continuous full spectrum and great customer service:
“The SK450 produces a continuous spectral distribution that is close to daylight, it uses name brand LEDs, does not require an internal fan due to the impressive thermal management design and comes with 90 degree TIR lenses to concentrate the light on the plants.” Review from canybus.com
“You may note the Super Grow LED banners on this site, we only recommend these lights because they are the best on the market beating the likes of Advanced, HydroGrow and Prosource. Why? To start with they beat those other companies hands down on a $ per sqft of flowering basis and deliver higher yields per Watt than HPS lights.” Review from greenthumbgrowing.wordpress.com
“I just finished my first hydroponic grow and the LED lights are efficient and produce the estimated 1g per watt. My entire household electricity was $60 last month and I’m running a hot water spa. It’s great not to have to switch the lights out between cycles. My home was built in 1953 so traditional lighting systems weren’t an option for me unless I spent a lot of money on upgrades etc.. The temperature in my grow room rarely gets above 85 degrees and usually runs about 78 degrees – no air cooling – just an efficient fan. Lastly, you’re not on your own once you purchase this product – no really – the response to my questions and concerns have been extremely prompt.
It’s great when a product does what it claims to do so you can plan ahead and count on it.” Review from supergrowled.com
#6: Kind LED
Model: K5 XL1000
Kind LED was founded by real growers with years of hands-on experience. They painstakingly developed their technology as they realized the full potential of LED grow lights. With the K5 series LED grow light Kind is setting a new industry standard.
Most LED grow lights have a small “footprint”, which means they don’t fully cover the square footage of cannabis canopy. This has traditionally resulted in lower harvest yields from full spectrum LEDs when compared to HPS. The K5 series has an extra-large footprint, making these lights true replacements higher wattage HPS lights.
Actual Draw in Watts
The actual draw of the K5 1000 is 650 Watts.
Kind LED advertises this light as a true replacement for a 1000 W HID.
The K5 XL1000 has 320 LEDs, in a blend of 3W and 5W diodes.
Grow Light Spectrum
The K5 models use a 12 bandwidth spectrum which covers the entire photosynthetic growing spectrum. It is dimmable, allowing the grower to customize the spectrum to suit vegging or flowering cycles.
Their spectrum ranges from 350 nm – 740 nm, covering the entire PAR spectrum.
Natural Light Cycle
The X1000 mimics the natural light cycle by moving through eight different stages during the day. It starts off with a dawn setting, gently waking up your plants. Then it moves gradually through the intensity of midday before slowly dimming into sunset and eventual night. The natural light pattern results in higher yields and more natural growth patterns.
There are four large diameter fans that run over several heat sinks to effectively dissipate any heat generated through the light cycle.
25 square feet (5’ X 5’)
This grow light uses a secondary optical lens.
Peak Photon Delivery in µmoles, PPFD
Kind LED offers some of the most useful PPFD data we’ve come across. They provide measurements at realistic distances from the light. They also give averages for the inner and outer edges of the coverage area.
Here is their data, comparing their XL1000 to 600W and 1000W HPS cooltube lights.
All measurements are in µmoles/m2/s:
|Kind XL1000||600W HPS cooltube||1000W HPS cooltube|
Build Quality and Materials
Everything in a Kind LED grow light is manufactured by Kind, right down to the screws. They don’t outsource to anyone, so they can ensure that every light is the highest quality possible.
- XL1000W – 26” X 20” X 3.5”

Illumitex is an American company based in Austin, TX that is fully vertically integrated, meaning that they own their supply chain. This gives them the opportunity to manage the quality of their lights at every stage of manufacturing.
The NeoSol DS from Illumitex is another LED grow light designed to maximize efficiency. It is dimmable down to 10%, so you can adjust the amount of light reaching your plants without moving it up or down. The adjustable LED bars allow you to direct light exactly where you want it.
The light itself provides uniform distribution and silent operation. Illumitex partners with research companies like the world renowned Syngenta to continually improve their LED lights. The NeoSol DS is their latest offering.
Actual Draw in Watts
The actual draw of the NeoSol DS is 457.9-508.8 Watts. The fluctuation is due to effect of heat on the efficacy of the Surexi diodes.
The NeoSol features 96 ultra-efficient Illumitex Surexi arrays, each of which is 5.4 Watts.
Grow Light Spectrum
The Illumitex Surexi F3 Spectrum LEDs use a mix of four wavelengths designed for the best vegetative and flowering results. In addition to the common blue and red wavelengths it includes a small amount of green which increases the quality of your yield. Here’s the breakdown:
- 400-499 nm (Blue) 11%
- 500-599 nm (Green) 7.7%
- 600-699 nm (Red) 81%
- 700-780 nm (Deep Red) 0.3%
This is a fanless system that uses a passive heat sink to keep cool.
The 520 Watt NeoSol replaces a 1000 Watt HID, and covers 16-25 square feet depending on the growth stage:
- Vegging: 5’ X 5’

Model: King 1200W
You may be wondering how this light made the list. It is made in China, by a Chinese company no less. At first glance, I didn’t think it was much either. But a little research showed that these lights actually work great.
These are the best cheap LED grow lights on the market right now. And sometimes cheap is important.
The King 1200W has a color band spectrum with peaks in the right places (matching PAR). It has a high intensity output. Many growers are seeing better results from this light compared with two 300W LEDs and even with 1000W HID lights.
As far as LEDs in this price range, you can’t beat the results you’ll see with the King 1200W. They are backed by a good warranty and the company is known for quality customer service. Plus they ship from inside the US, so you’ll get your lights quickly.
Actual Draw in Watts
The actual draw of this light is about 340W.
While this seems low, keep in mind that a large LED Wattage (1200W in this case) means that the light has a bigger LED driver. In turn, this creates higher intensity light (measured in lumens or PAR/Watt). The heavy duty 6W LEDs in the King 1200W give a better PAR/Watt than smaller 3W LEDs.
So this light uses less electricity but is able to produce intense light that will improve your yields.
This grow light uses 200 6W LEDs.
Grow Light Spectrum
The King 1200W grow light has color bands for vegetative and flowering marijuana stages.
- 410 nm (Deep Blue)
- 440 nm (Deep Blue)
- 450-475 nm (Blue)
- 620-630 (Red)
- 650-670 nm (Deep Red)
- 730 nm (IR)
KingLED reminds us that the IR wavelength is at the far edge of wavelengths visible to the human eye. It will look like these diodes are not working or are very dim, but they are helping your plants produce bigger, tastier and more potent buds.
This fanless light uses custom copper core heat sinks to quickly dissipate heat.
While the lighting area and height can be adjusted depending on your set-up, the average coverage is 5.5’ X 5.5’.
Build Quality and Materials
The King 1200W is not a cheaply made Chinese grow light. It has surprisingly tough materials and is built to last for years.
- Dimensions: 13.1” X 13.1” X 2.37”
- Expected Lifespan: >50,000 hours
The King 1200W comes with a 3 Year All Inclusive Warranty.
Here’s what growers think about the King 1200W Grow Light:
“This light was leaps and bounds ahead of my two 300w’s (and I want to mention they are very good LED lights that have good par/per watt performance and are new technology). I couldn’t believe how fast the plants put on weight and growth, it was near explosive growth.” Review from amazon.com
“This is a great grow light for the indoor grower. It is a good investment for your growing needs and I highly recommend this product. Great light for a great price I’ve been using it and I couldn’t be happier with the results of my grow.” Review from amazon.com
“I bought a 1200w w/6w bulbs from China for 300.00 and its works 5 times better than my 1000w Gravita.” Review from boards.cannabis.com
#10: Advanced LED Lights
Model: XTE Series 300
The XTE series is the latest innovation from Advanced LED Lights. These American made grow lights outshine even their original Diamond Series thanks to many hours of research.
The XTE 300 uses 5W high flux LEDs which output twice the power of competing 5W diodes. In addition to the boost in power, you are in full control of the spectrum output and intensity. This makes it easy to adjust the lights instead of changing their height for different stages in the grow.
With a quality build, great diodes and a strong PAR/Watt output, the XTE 300 is a grow light to be reckoned with.
Actual Draw in Watts
The actual draw of the XTE 300 is 252W.
This grow light uses a combination of Cree XT-E 5W LEDs and Osram 3W LEDs.
Grow Light Spectrum
With the XTE series you are in full control of the spectrum. You can change the “season”, spectrum peaks and intensity of the light with Advanced LEDs upgraded Color Select Controls.
Advanced LED claims that their ColdFlo Heat Dissipation Technology keeps the powerful 5W lights cool better than any other system out there. They were not willing to tell us more about it. Reviewers say it works, so we’ll have to go with that for now.
The XTE 300 has a total coverage of 3.5’ X 4’, with a core coverage of 3’ X 3’.
The XTE series used the Diamond Series Optic built-in reflector to direct extra light at the garden.
Peak Photon Delivery in µmoles
The one complaint we have with Advanced LED is that they decline to share much information. In a phone call I was told that the information on their website is all that they “are allowed” to release. It doesn’t include PPFD data.
Customers seem to love these lights and say they live up to all the claims Advanced LED makes. So we can’t judge them too harshly. These appear to be really great LED grow lights, but we would love to have just a little more information about them.
If you’ve used the XTE series for a grow, please share your experience in the comments section below. Devendra please link to the comments section.
Build Quality and Materials
Advanced LED uses quality US made materials for all their grow lights. The XTE series has parts that are easily removed and replaced. Even if you encounter an issue you can usually make the repair yourself with parts supplied quickly and free of charge from Advanced LED. This means less time fooling around and more time growing great weed.
- Dimensions: 19” X 8” X 3”
- Weight: 18 lbs
90 Day Risk Free Trial- You get a full flowering cycle to decide if you like it or not. No hidden fees or questions asked.
Advanced LED’s Limited Lifetime Warranty is one of the best around. Here’s the breakdown:
- First 3 Years: If a defect occurs Advanced LED will either provide replacement parts immediately, repair the light (they pay shipping) or replace the light with a new one.
- After 3 Years: Advanced LED will provide all parts. Customer is responsible for shipping and labor.
Growers everywhere love the XTE series from Advanced LED Lights:
“One thing I noticed about the new XTE series is with the reflectors built in to the secondary lens hardly no light is wasted out the sides of the lens, most cluster panels the whole cluster lights up due to wasted light. The XTE series clusters don’t.” Review from 420magazine.com
“I am using the Advanced LED XTE 300’s in my garden and couldn’t be happier. The panels are well built, using top brand diodes (Cree and Osram) which will last much longer than cheap epistar and epiled diodes found in 90% of the LEDs on the market. I would highly recommend them.” Review from icmag.com

The Diamond Series XML from Advanced Lights are one of the first LED grow light arrays to feature the 10W Cree XML LEDs; a breakthrough in LED technology that massively increases the power of LED grow lights. These LEDs deliver over 1,000 lumens each at full power and are run here in conjunction with Bridgelux 3W LEDs to make a very powerful grow light.
The ‘Diamond Series’ features two models
The difference in the two models is the size, with the larger unit (XML350) covering 4’6” squared as opposed to the 3’ squared of the smaller (XML150) unit.
- The XML150 has 4 X 10W Cree XML lights and 64 X 3W made up of 4 arrays of Bridgelux LEDs, each containing 16 LEDS. Total potential Watts = 40W + 192W = 232W
- The XML350 has 10 X 10W Cree XML lights and 144 X 3W made up of 9 arrays of Bridgelux LEDs, each containing 16 LEDS. Total potential Watts = 100W + 432W = 532W
Color select and dimmable controls are available for you to switch between different modes for different phases of growth. You can choose from clone/seedling mode, veg mode and flowering mode.
With dual heat sinks and fans the Diamond Series XML LEDs run cool and can lessen the need for heat ventilation in the growing area. You can also fit more of them into your grow room with the functionality that allows you to daisy chain up to 4 units from the same power supply.
If you are looking to totally maximize production from a limited space then this could be the light for you. The Diamond Series XML LEDs deliver more power than most of the competition with light across the spectrum to meet all your plants needs.
Each of the units emits light in 11 different wavelengths. This is not full spectrum but still good quality light.
Actual Draw or True Draw
Diamond Series XML150 – “Amps @ 110 Volts quoted at 1.6 and 220 volts @ 0.5.” Therefore @ 110 Volts, 1.6A = 176Watts or 76% of potential. Quite high, maybe their quoted amperage is incorrect.
Diamond Series XML350 – No Amps given. They claim 330 Watts which sounds about right = 330Watts or 62% of potential.

Area 51 LED
For those who prefer an all in one solution that best simulates natural sunlight Area 51 offer the XGS-190 LED grow light.
This switchable 100W/195W Cree XTE Warm White LED set comes with finned aluminum heat sinks plus two ball bearing fans and will operate on any voltage from 100 to 240 V without the need for providing any special drivers or cords to run on different voltages. These are the specific LEDs they use XTEAWT-02-0000-00000BFF6.
Unlike some LED units the Area 51 does not offer you the ability to switch between different modes that optimize the light frequency depending on your plants’ growth phase. It does however offer 2 power settings that allow you to choose from 100W actual draw and 195W actual draw to adapt the unit to your spatial needs. These two options can also be used to provide gentler lighting to young plants and then to ramp it up during flowering.
The Area 51 XGS-190 LED Grow Light is designed to allow you to daisy chain up to four lights from a single power source (check your circuit breaker) by simply connecting them in series.
Each Area 51 XGS-190 comes with adjustable ratchet hangers and provides high energy Warm White lighting that is suitable for growing plants throughout the grow cycle. It seems like a good option with a reasonable price for providing good quality light that your plants will surely like.
Only mentioned in terms of the LED “Cree 5w warm white 3700k” here is the datasheet from CREE. “The XT-E LED delivers up to 148 lumens and 148 lumens per watt in cool white (6000 K) or up to 114 lumens and 114 lumens per watt in warm white (3000 K), both at 350 mA, 85°C”.
72 LEDs x 5W = 360W potential
Switchable between 100W or 195W, as stated by Area51, these sound like reasonable actual Watts given a potential of 360W.
Cree XTE Warm White 3750k. See spectrum above.
Aluminum Heat Sinks with 2 X 120mm ball bearing fans. Each fan operates at 73cfm and makes an almost silent 10dB. Operating temperature: 77F – 86F / 25C – 30C (generally operates a few degrees higher than ambient temps) They recommend that you keep your grow room between 70°F and 77°F.
The Area 51 XGS-190 LED is robustly housed in a vented aluminum casing. It measures 12” X 18” X 2.75” (30cm X 45cm X 7cm).
The recommended growing area for the Area 51 XGS-190 LED is:
- Veg 100W – 24” X 30” (61cm X 76cm)
- Veg 195W – 39” X 39” (99cm X 99cm)
- Flowering 195W – 30” X 30” (76cm X 76cm)

Models: Full Spectrum G8LED Veg/Flower Lights 900 Watt & 450 Watt
G8LED lights from Dorm Grow are extraordinarily efficient grow lights which are used to full capacity during both vegetative and flowering cycles. Unlike many LED vendors, Dorm Grow combines ultraviolet and infrared diodes in their unique G8LED lights. The extra wavelengths maximize plant growth and yields while saving hundreds of Watts of electricity each hour. With penetration of up to five feet past the plant canopy, it is no surprise that these lights have received rave reviews and been awarded a High Times Magazine Gear of the Year award in 2014. Reviewers have gone so far as to say there are no cons to be listed for G8LED lights.
The Full Spectrum G8LED Veg/Flower Lights are available in 2 sizes:
- 450 Watt G8LED Full Spectrum Veg/Flower
- 900 WattG8LED Full SpectrumVeg/Flower
The smaller unit covers over 12 square feet of growing space, while the larger model can accommodate over 24 square feet. By placing two or more G8LED lights on 4 or 6 foot centers respectively you can increase the grow area further through cross coverage.
- According to Dorm Grow, the 450 Watt unit will replace an 800 Watt MH/HPS System with a power draw of 280 Watts
- The 900 Watt unit will replace a 1400 Watt MH/HPS System with an power draw of 540 Watts
The G8LED lights each emit wavelengths along the Optimal 8 band system that Dorm Grow has formulated, including wavelengths in Infrared and Ultraviolet plus 6000K white. After extensive research and testing, Dorm Grow found a weighted average ratio of wavelengths used by plants throughout vegetative and flowering growth. They balanced their LEDs accordingly, creating a grow light whose efficiency is unmatched.
The G8LED wavelengths have been chosen to include the following three peak colors of the PAR spectrum and the surrounding wavelengths:
630 nm (red)
480 nm (blue)
580 nm (orange)
Dorm Grow explains that more bands are unnecessary, as their 8 carefully chosen wavelengths cover all the light necessary for rapid growth and high bud yields. Users seem to agree, describing these lights as durable, efficient and contributing to some of the highest yields they have ever achieved.
G8LED lights are unique in that they do not have a switch to turn off red diodes during vegging and back on during flowering. Instead the lights are used at full capacity and add on 90 W Red during the flowering period in place of decreasing the number of it diodes during veg.
- 450 Watt G8LED Full Spectrum – 150 x 3W
- 900 Watt G8LED Full Spectrum – 300 x 3W
Both the 450 Watt G8LED Full Spectrum and the 900 Watt G8LED Full Spectrum lights use a combination of Bridgelux, Epistar and Optotech diodes.
Actual Draw or True Draw
- 450 Watt G8LED Full Spectrum– “Amps @ 110 Volts quoted at 2.49 and 240 volts @ 1.0.” Therefore @ 110 Volts, 2.49A = 280 Watts or 54% of potential.
- 900 Watt G8LED Full Spectrum– “Amps @ 110 Volts quoted at 4.9 and 240 volts @ 2.0.” Therefore @ 110 Volts, 4.9A = 540 Watts or 54% of potential.
The actual draw of both models is slightly lower than the power draw listed on their site, which work out to 62% and 60% of potential respectively.
With 6internal cooling fans in the 450 Watt G8LED and 8 in the 900 Watt G8LED both stay cool to the touch and require no extra heat ventilation.
The G8LED Full Spectrum lights are solidly built and durable to last for many years. Dorm Grow is known for quality construction. You can expect to get over 50,000 hours from these lights, which means you could use them for up to 10 years if you treat them well!
- 450 Watt G8LED Full Spectrum– 17.5” X 11” X 3” – weight: 17.8lb
- 900 Watt G8LED Full Spectrum–20.5” X 14” X 3” – weight 24.8lb
- 450 Watt G8LED Full Spectrum– 12 square feet
- 900 Watt G8LED Full Spectrum– 24 square feet

The Dual Aurora Puck Kit from Rapid LED is a self assembly LED array that allows you to build your LED lighting unit to your own exact requirements.
If you have some experience of Electronics, LEDs and series circuits then self assembly is a great way to save costs, building yourself a top of the range LED grow light without having to pay top dollar for pre-assembled units.
For simulating daylight the Dual Aurora Puck Kit (Dimmable) seems a good solution as it presents 4 channels of control and 7 colors of LEDs: 4 XP-G cool white; 4 XT-E royal blue; 4 XP-E blue; 4 Violet UV; 2 XP-E Green; 2 XP-E Red; and 1 XP-E Red-Orange. Apart from good mimicking of natural daylight, thus covering the photosynthetic spectrum, this set allows you to create different combinations of light colors which then can be used to stimulate marijuana’s vegetative or reproductive growth (flowering) requirements, depending on your interests.
The 4 channel arrangements are:
- Channel 1 (1000mA max) – 4 royal blue + 3 blue;
- Channel 2 (700mA max) – 2 green + 1 blue + 2 red + 1 red-orange;
- Channel 3 (1500mA max) – 4 cool white:
- Channel 4 (700mA max) – 4 Violet UV.
The Dual Aurora Puck Kit (Dimmable) comes with current and fan adapters and dimming accessories. There are also clear and thoroughly explained instructions which allow you to create, adapt and experiment on different environmental conditions.
We asked Rapid LED directly and they stated:
We emailed them about our review.
Thank you for thinking of us! The theoretical wattage draw of the Aurora Puck is about 65w. However, this is when running each channel at exactly the max current as specified on our site here: http://www.rapidled.com/aurora-puck/
That is correct, it’s just a calculator that multiples current (mA) times volts to find watts.
a) We provide a maximum current for each string here: http://www.rapidled.com/aurora-puck/
The actual current you’ll use is really up to you and your tank/needs, some people will run at 100% of our recommendations, most are at 70-90%, but I’ve seen some go as low as 30-40%.
b) The 110V isn’t the voltage you’re using to calculate wattage, that’s simply the input AC voltage to the driver. The driver then converts that to DC voltage (if you’re using a LDD driver the power supply would do the converting for you but it’s essentially the same thing). You’re going to look for the DC voltage draw of each LED, which will vary depending on the current. For example, here’s the datasheet for our XT-E royal blue LED:
Look at page 8 of the datasheet and you’ll see a chart showing you the relationship between current and voltage. For example, if you’re running the LED at 1000mA (the max we suggest for channel 1 on the puck) the LED will draw about 3.2V. Thus, you will multiple 3.2V x 1.0A to get 3.2 watts. This is the true wattage draw of the royal blue LED at 1000mA (1A). You simply add up the wattage draw of each LED on the puck to find the total draw for the puck.
c) Each LED will output a different wavelength. I don’t have a spectral graph of the output on the entire puck, but if you click on each LED’s product page (linked at the top of the puck product page) we’ll tell you the wavelength of each LED. For example, the royal blue is 450-465nm, the blue is 465-485nm, etc. The only one that won’t have a nm is the white LED as those are full spectrum and thus are always rated in Kelvin temperature (the higher the temperature the cooler the LED).
Hope that helps clear things up, if you have any other questions please feel free to let me know.
Thanks for your reply.
I am unsure of the draw and electronics so I need some help here as normally I would work out the true wattage when I have the Voltage and the Amps (current) using thishttp://www.supercircuits.com/resources/tools/volts-watts-amps-converter . Please assume I have just bought one of your kits, which comes with two pucks, what would the be the answers to the following assuming I am an average home grower?
a) What current/Amps should I use?
b) What would that current draw in Watts assuming 110 Volts for the entire kit combined, total of two pucks?
c) Also, what is the spectrum of the output in nanometres?
Thanks in advance for your time.

Black Diamond LED
There are two size options in the Black Diamond range from Lil’Tomato Concepts.
Each offers high output LEDs that run at 5500/73 K/CRI. The smaller Black Diamond has 48 LEDs whereas the larger Double Black Diamond has 96.
Lil’ Tomato advertize their lights as operating at 115 W and 228 W potential.
As with XGS-190 LED Grow Light, both these Black Diamond LED Light V2 sets operate over a voltage range, here from 110 to 240 V. To work out the actual draw for you, use this handy calculator and enter your home voltage in the top box and either 0.89 (for the Black Diamond) or 1.89 (for the Double Black Diamond) in the bottom box. The answer in the middle box is your actual power draw.
Lil Tomato go on to suggest an input of 120 Volts at 0.89 Amps which equates to 107 Watts true draw. The Double @ 1.89 Amps and 120 Volts equates to 227W. This is because LEDs never run at maximum power all the time. This would be like always driving your car at full revs; it would soon wear out!
Overall, and understandably, these sets are a bit more expensive than the XGS-190 LED Grow Light set. However, Lil’Tomato Concepts come with proven experience in the field of agricultural lighting and offer you a 5 year warranty period.

The Black Dog LED Universal Series is a solidly constructed LED grow light series that relies on proven 5W LED technology to deliver powerful PAR lighting to your plants.
This model, The BD360-U, is a mid range model that is suitable for home growers with a 4’ square growing area. It more than adequately replaces a 400W HID and features 140 5W single chip LEDS.
Black Dog Universal Series LEDs use the trademarked ‘Phyto-Genesis-Spectrum’. This is the result of extensive research and uses 15 different colored LEDs to create a spectrum that closely mimics the graph below which shows the rate of light absorption of different plant pigments.
The full spectrum created goes from UV to IR and covers crucial absorption peaks in the red, orange, violet, and blue spectrum. This represents optimum lighting for both flowering and veg. For vegetative growth the light covers a 4’ square and should be hung at 22” from the canopy. Lower the light to 16” for flowering to cover a 3’ square.
Having a square footprint is more efficient than some of the rectangular footprints available and can make for easier grow room planning.
The Black Dog BD360-U LED has a capacity of 700W but only actually draws 340W when running. This prolongs the life of the LEDs and keeps your energy bills low. Extra large heat sinks are used to keep operating temperatures low, allowing you to get your plants closer to the light source.
Black Dog LED lights enjoy an excellent reputation and the BD360-U is a great buy that comes with proven performance and productivity.
Black Dog claim: “BDL’s proprietary full-cycle Phyto-genesis Spectrum™, which eliminates the need for separate vegetative and flowering grow lights”. “Includes multiple wavelengths targeting crucial absorption peaks in the red, orange, violet, and blue spectrum, as well as IR and UV.”
We have not seen any tests outlining spectrum, PAR or nanometers.
140 X 5W = 700 Watts potential
Black Dog claim 340W actual draw which is 48% of potential, this is in the ball park of reality. We checked, given the amperage is 2.8-1.4A (@ 120/240v) this equates to 336 Watts true draw, so they are bang on correct.
5W High Output LEDs – no brand name given
Black Dog use some of the ‘largest heat sinks in the grow light industry’ to keep operating temperatures down. Operating temperature range of -20 to 40 °C. BTU of 1161.
The BD360-U comes in a sturdy black metal frame that is oversized to allow for extra heat dissipation. The side panels are designed with good venting and the unit comes with D rings and adjustable metal ratchet hangers. CE certified and ROHS compliant.
The recommended growing area for the BD360-U is:
- Veg 48” X 48” (121.9 X 121.9)
- Flowering 36” X 36” (91.4cm X 91.4cm)

BML Custom LED
BML offer an array of lights from the SPYDR 1000 and 600 Grow Max Spectrum models to the 600 Start-Max Spectrum.
You can even build your own spectrum lights, find a length from 7” through to 72” and the angle of the beam from 30 ° to 90 °.
To create the best LED combinations that mimic natural daylight for your plants and are suitable for the physical conditions that you have (i.e. space, temperature, humidity), BML offers you a most convenient custom LED tool you can create and see how your own custom made LED spectrum will work.
With reviews from PhD’s at Princeton it is seen as a quality light “In my opinion, BML Horticulture is an ambassador of the LED revolution and is a great partner for plant science!” Paul P. Gaulthier, PhD.
By selecting your preferred fixture length and creating a circuit board with any LEDs (up to 15) of your choice together with choosing the beam angle you want in your fixture, you will have the opportunity to evaluate, experiment and compare many different light conditions and scenarios that you can offer to your marijuana plants.
Depending on length, fixtures can have a different number of circuits. These custom made fixtures come with a three year unconditional warranty against defects in workmanship or materials. With the different set of LED colors offered BML you can build an enormous variety of spectrum ranges and built different sets of LEDs specific for different development stages of your plants, e.g. vegetative vs. reproductive growth, according to your own needs. In addition to this most helpful builder and to help you choosing the best LED combinations, BML, bmlcustom.com/custom-led-strip, also offers you a graphical tool where you can analyze and compare the different values of the physiological parameters that matter created by a given LED combination. For example, you can see the wavelength (color) predominance and the resulting PAR (Photosynthetically Active Radiation) of a given LED combination and fixture that you chose. This way you can see which region of the light spectrum is most represented and evaluate which developmental stage of your plants are you favoring most, i.e. vegetative vs. reproductive growth.
SPYDR 600 GROW-MAX Spectrum – They state it covers PAR >> “Spectrum is the perfect choice if you need to take young plants to maturity with maximum vegetative growth and flowering capacity.” “When the bars are centered in the fixture to achieve max PAR levels, you can expect PPFD readings of up to 2100 mmol/m2/s at a 12″ mounting height.”

Cool Diamond LED Lights from Lil’Tomato Concepts are built on the same sturdy framework as their Black Diamond LED sets. As with Black Diamond they offer two different sizes.
- Cool Diamond LED Grow Light
- Cool Diamond LED Grow Light II
Although of the same size as the Black Diamond sets, Cool Diamond LEDs squeeze more power out of the same area, providing 64 and 128 LEDs respectively. More light energy into your system means more weed out! As with other LTC products, the Cool Diamond LED lights also operate over a voltage range, here from 110V to 240V.
The specs on the Cool Diamond show an actual draw of 147W and 300W respectively @ 120 Volts and 1.23 A and 2.5A respectively.
If your domestic voltage is 110V then this equates to an actual power draw of around 135W and 275W respectively. The reason for the difference in this is that the LEDs do not continually run at full capacity as that would drastically shorten their life time. What this means to you is even lower utility bills than expected.
If you live somewhere with voltage other than 110V then you can use this simple calculator to work out what the actual power draw of the Cool Diamond LED lights would be for you. Just enter your domestic power supply in the top box, then enter either 1.23 for the Cool Diamond, or 2.5 for the Cool Diamond II, in the bottom box. The result in the middle box will be your actual power draw.
The Cool Diamond LED lights are a step up from the Black Diamond sets in price, but they provide much more power to your grow, enabling you to increase output for the same sized growing area. Basically it means fatter buds and bigger yields.
5,500–6,000 K Vertical daylight is the concept there, they do not mention nanometers however this sounds like good white broad spectrum light.

Model: Apollo 240 X 3W
The Apollo 240 X 3W LED grow light, from Growblu of USA, is a high quality full spectrum grow light that is rated to replace a 1000W HID.
The Apollo 240X3W uses 240 3W LEDs clustered into 16 pods of 15 individual LEDs. This amounts to 720W of LED power, although Growblu state the actual power draw of this light is only around 500W.
We calculated the actual draw using this calculator and, using the 5.4 amps stated by Growblu, found the actual draw at 120V to be 648W.
Either way, it would lower the running costs of the 1000W HID it replaces, as well as significantly lowering the high operating temperatures that are associated with HIDs.
To keep operating temperatures down, the Apollo 240 X 3W grow light uses aluminum PCB modules and a 2 cm premium aluminum heat sink. For added cooling there are also 8, quiet, high output cooling fans. All of this keeps operating temperatures at the canopy (12” from lens) at just 79oF, creating minimal need for you to supply extra ventilation for cooling.
The Apollo 240X3W uses a selection of top quality 3W LED chips from Bridgelux and Epistar to create their own, proprietary full spectrum. The actual breakdown of the spectrum is not available. However it is suitable for all your plants’ needs from germination, thru veg, to harvest. Each LED is fitted with a primary 90o lens and a secondary 60o focus lens for maximum light penetration.
The Apollo has an independent on board monitoring system that keeps an eye on how the LED grow light is performing. Any malfunctions with the lights are indicated by flashing or extinguished lights on the side of the casing. This allows you to address any problems that may occur immediately.
The Apollo 240 X 3W is a powerful light. Growblu give the optimal footprint as 4’ X 4’. The long rectangular shape of the light might be awkward for some tents or smaller rooms. However for larger commercial grows, several of these side by side would supply excellent coverage.
The Apollo performs equally well at either110V or 240V. Growblu will even supply the unit with the correct plug for the country that you live in. We contacted them for information for this page and they responded quickly to all our questions
They state “Proprietary Groblu full spectrum” with no other details.

Advanced LED Grow
The Grow Sun 320P LED grow light is one of the 5g Grow Sun Series. It offers single 20W LEDs with 12 multi-chips emitting in 12 bandwidths of light to give you great spectrum coverage for your plants.
The Grow Sun 320P features 16 of these 20W LEDs and is shipped in directly from the manufacturers in China and available from Advanced LED Grow of USA. Chinese LEDs can sometimes get a bad rep but there are a number of online reviews backing up the efficacy of this unit.
The Grow Sun 320P is designed to be comparable with a 400W HID. Side by side tests show an increase in yield of around 20% and a corresponding drop in energy use of around 30% with the actual draw of the Grow Sun 320P being around 280W on full bloom.
Grow Sun state that their bandwidths run from 400nm to 760nm plus white. Optical lenses are used to blend the light into the full spectrum but Grow Sun do not stipulate the individual chip frequencies. An acrylic sheet with reflective covering makes best use of the light, focusing it directly onto the plant canopy.
The Grow Sun 320P comes with an advanced wireless remote control with timer and the choice of three channels to meet the requirements of different stages of plant growth; seedling, veg and flower. The intensity of light with each channel is also adjustable from 10% to 100%. Each 20W LED comes with a solder free design that makes changes individual chips easy.
A built in safety feature lowers the light intensity of the GS320P should overheating occur. A trip switch is also fitted to cut off power in the event of an accident.
With hanging kit included, a one year full warranty, free tracked FEDEX shipping and the possibility of paying with Paypal, the GS 320P is worth a look at. We contacted Advanced LED Grow and found them very communicative and easy to deal with.
Check out this Youtube clip of the Grow Sun 320P grow light in action.
12 bans covering 400 – 760nm. We are sure there will be gaps in that spectrum but still 12 is a good number and close to full spectrum.
16 X 20W = 320 Watt potential. These are multi chip LEDs with multi spectra in them.
280W is what they quote, there is no discussion on Amps. We think that 280 is too high and not correct as that is 87% of potential, so either the LEDs will burn out (1 year warranty) or they are driving them at far less than this actual draw, maybe 160 to 180Watts.
Email from Advanced LED Grow “The actual power draw of the Grow Sun 320P is 280W. Attached is a brochure on the unit with a light source test report that shows the distribution of the LED light.”

The Grow Sun 320P is an attractive unit with gold effect aluminum casing for those who like a bit of bling with their grow.
Grow Sun give us the levels of coverage for the 320P at varying heights above the canopy. Obviously you would lose a great deal of the intensity at the higher levels and only be able to flower effectively at the lower levels.

In the same line as Dual Aurora Puck Kit (Dimmable) and BML LED combinations, there is a brand new 80 Watt LED panel and upgraded version of the famous Hans-panel from Bonsai Hero.
Bonsai Hero offer the 65W and 80W models. We concentrate on the 80W model here.
Bonsai Hero’s Hans Panel combines 4 Cree XBD Royal Blue, 17 Cree XBD 701 Red, 2 Cree XBD White and 10 Osram LH-CPDP Deep Red Rebel LEDs. The difference and main advantage of the Hans Panel is that this LED panel is optimized for a higher current and delivers 15% more light than the standard 65 Watt Hans-panel. However, both versions are among the very best LED color combinations on the market today.
The Hans Panel allows you to optimize the spectrum and the amount of light you deliver at different developmental stages of your plants’ growth. This way you can provide optimum lighting conditions whether you are growing seedlings or cuttings, vegetative growth or flowering.
- Growth Phase – Seedlings and clones. Power draw = 38W
- Early Flowering – Mothers and first weeks of flowering. Power draw = 60W
- Full Flowering – Thru to harvest. Power draw = 80W
Hans Panels have no light losses caused by plastic covers or lenses in front of the LEDs. Patented reflectors are used instead.
The Hans Panel comes with an external, waterproof power supply that doesn’t add any heat to the array. The whole unit operates at a mere 45dB, this almost silent noise output is a must for stealth growers.
There is no mention of actual spectrum but they offer a good selection of LEDs. There are 3 selectable positions;
(1) Seedlings and cuttings;
(2) Mothers and Early weeks of flowering;
(3) Full flowering position. Easily selectable by switch.
Max 80 Watts quoted which sounds reasonable. No mention of Amps used.

Hydro Grow LED
Hydro Grow LED from Monroeville, PA., have cemented an excellent reputation for themselves over the past few years for their LED grow lights.
Their SOL Series covers a wide range of needs, from the SOL 1 which is suitable for supplemental lighting or single plant grows, up to the SOL 9 which is equivalent to 750W of HID lighting.
The SOL Series is based around integrated LEDs that come in the choice of either 50W or 100W. The 50W LEDs contain 32 individual 3W chips whereas the 100W LEDs contain 64.
Here we take a look at the mid range SOL 6, a powerful grow light with 6 of the integrated LED units. You can choose the 300W model which operates with the 50W LEDs or the 600W model which runs the 100W LEDs.
Because LEDs don’t run at full power all of the time the actual power draw of these LEDs is not 300W or 600W respectively. The true actual draw can be calculated by using this handy calculator. Given the amperage supplied by the manufacturer we can calculate that the actual power draw of the SOL 6 is as follows.
|SOL 6 Model||110V – Actual draw||220V – Actual draw|
|SOL 6 300W||275W||286W|
|SOL 6 600W||539W||396W|
The LEDs used by Hydro Grow LED are Top BIN LEDs. Binning is a process that grades individual LEDs according to their brightness. Top BIN LEDs are the best quality LEDs available.
Hydro Grow LED use their own 3rd Generation light spectrum that emits light at 440nm, 470nm, 525nm, 640nm and 660nm. The spectrum breaks down to around 10% blue, 15% green and 75% red.
The SOL 6 is an elegantly designed unit with the 6 integrated LEDs mounted in Fusion reflectors. These Fusion reflectors are patent pending and focus all the light from the LEDs into a concentrated beam. No lenses are used.
The SOL 6 LED grow light has a future proof modular design that is easily upgradeable should the need arise. Extra units can be daisy chained to a maximum of 1200W. Units are available with 110V or 220V power supplies.
Each LED has a dedicated 80mm dual bearing fan and custom built thin finned heat sinks to keep operating temperatures low.
We contacted Hydro Grow LED for information and found them very helpful and quick to respond. Nice work guys.
They state “tested PAR output matching that of a 600W HPS!” But then mention that it is bands, “440, 470, 525, 640, 660”. So this is not full spectrum.
Email from HydroGrow: “Our 3rd Gen light spectrum was broken down into 10% blue, 15% green and 75% red based on lumen output. I cannot break down the individual wavelengths into their percentages.”
- SOL 6 300W – 6 X 50W = 300W potential (192 individual chips)
- SOL 6 600W – 6 X 100W = 600W potential (384 individual chips)
- SOL 6 300W – 275W – 2.5A @ 110V (1.3A @ 220V = 286W)
- SOL 6 600W – 539W – 4.9A @ 110V (1.8A @ 220V = 396W)
Email from HydroGrow “The 50W LED contains 32 chips in total, while the 100W contains 64. The chips we use are 3W, however it is rare for a colored 3W LED to consume more than 2W of actual power. Likewise we do not drive them at full power as this would create too much heat.”
They mention they use Philips LumiLEDs ‘top bin’. Model numbers. LXM2-PD01-0050 and LXM2-PD01-0040 on their website.
However the email response was different:
Email from HydroGrowLED: “We do not use any LEDs one might typically consider “brand name” such as Cree, Osram, Luxeon, Nichia, etc… The reason for this is that their LEDs test out to produce approximately 1/2 the PAR output per watt of those we use in our products.”
Generic, 85V – 480V and the email reply stated: “The drivers we use are generic. I believe the power factor is around 92.”

The Titan 370W LED grow light is the biggest light in the Solar Core line from Solid Apollo of Washington State, USA. It has been designed with the larger scale grower in mind and has a core coverage of 27ft2.
Solid Apollo also offer the Ares LED Grow Light @ 120W and the Midas @280W. We review the Titan @ 370 Watt.
The Titan 370W is a good looking, sturdily built, modular high tech light that comes with all the confidence of a 120 day money back offer or 5 year warranty.
The driving force behind the Titan 370W LED comes from the 10 X Full PAR spectrum LED grow lights from the industry renowned Bridgelux. These LEDs are combined with 120o polycarbonate lenses to ensure effective coverage of the whole growing area. Each of the ten light ‘cores’ contains 15 individual 3W Bridgelux LEDs. This makes a total of 150 individual diodes in the following light spectrum:
- 10x Infrared 730nm,
- 10x Deep Red 660-670nm
- 60x Red 640-660nm
- 10x Orange-Red 620-630
- 20x Red 630-640nm
- 10x Blue 460nm
- 10x Cobalt blue 430-440nm
- 10x Violet 410-420nm
- 10x Warm White full spectrum 3000K
This creates a full light spectrum with extra oomph at the red end, ensuring good coverage of the chlorophyll A and B peaks, the most essential wavelengths for your marijuana plants’ growth.
This Titan 370W LED is designed to replace 800W of HID lighting power and can easily grow up to 15, medium sized marijuana plants. 150 X 3W LEDs actually equals a maximum power of 450W. However, LEDs are never run at maximum capacity as this would just burn them out too quickly. You can calculate the actual power draw of the Titan for yourself by using this calculator. The input current is 2.5amps. At 120V, the actual power draw is 300W. This low power consumption can help you to slash the considerable energy costs of your grow.
Heat management in the Titan 370W comes via 6 whisper quiet 90mm fans and effective side venting. These Bridgelux LEDs are 98% efficient at creating light meaning that the heat created is kept to a minimum anyway.
The Solar Core Titan 370W LED comes with a sophisticated on board LED diagnostics system (LDS). This system constantly monitors your grow light and provides you with an up to date status. Any faults or problems with the system are notified by a flashing light to indicate which individual LED is giving you trouble. Although, with an expected lifespan of 50,000 hours on the LEDs, you shouldn’t be seeing too much of this.
We contacted Solid Apollo whilst gathering information for this article and found them quick to respond and helpful with providing information.

Super Grow LED
Known as one of the Rolls Royce LED grow lights on the market. Super Grow LED offers two models. Our people use them. So do a number of the big Dutch seed companies.
- Super Grow LED SK450
- Super Grow LED SGL6
The SGL6 is the smaller of the two and great for small grows and supplemental lighting. The SGL6 has 28 X 3W LEDs with an actual draw of approximately 25 Watts.
The SK450 is the larger of the two lights and has 150 X 3W LEDs to offer a 450W capacity light with an actual power draw of approximately 250 Watts.
The concept with the SK450 is that two units, total draw of 500 Watts, would replace your 1,000 Watt HID unit. In the process you would save at least 50% in electricity compared to an HID unit, more if you consider there is no ballast needed and a reduction in HVAC requirements.
Both the SLG6 and the SK450 offer a full spectrum from 420nm through to 750nm with no gaps or bands missing. Other features include high end heat sinks which require no fans, eliminating noise and further lowering energy bills. The solid state construction is extremely durable and SuperGrowLED back this up with a 5 year warranty.
Both lights have top of the range 45mm (not the cheaper 39mm) Bridgelux and Epistar LEDs with 90° and 120° beam angle PMMS lenses for greater photon delivery. Optimum photon delivery is at 12” and has been measured at 1000µmol.
Both the SK450 and the SGL6 come fitted with US plugs but will work worldwide on different power supplies in different countries. There is no need for transformers, simply buy an international plug adapter and you can use them anywhere in thw world.
The SK450 and SGL6 from SuperGrowLED are high quality grow lights with a great track record. Whether you want some small supplemental lighting or a replacement for your HIDs, SuperGrowLED can supply you with cutting edge LED lighting technology to suit your needs.
True full spectrum no gaps, no bands, 420 nm through to 750 nm right into IR.
- SK450 – 150 X 3W LEDs = 450W potential
- SGL6 – 28 LEDs X 3W LEDs = 84W potential
- SK450– 250 Watts (250W / 120VAC @ 2.1A)
- SGL6– 25 Watts (25W / 110VAC @ 0.23A)
Bridgelux and Epistar
- SK450 – 6th generation Spectrum II™ LEDs using 100 ‘white LEDs’. Individual ‘white’ LEDs are a mix of RGB to supply you with high end color rendering and a full spectrum. The remaining 50 LEDs are a mixture of ‘reds’ for extra power during flowering.
- SGL6 – 6th generation Spectrum II™ LEDs using ‘white LEDs’. Individual LEDs are a mix of the primary colors RGB to supply you with high end color rendering and full spectrum ‘white’ light.

Full spectrum lights carry the blue light for vegging and the yellow, amber, orange and reds for flowering and run between 420 to 750 nanometres.
You can replace a 1000 Watt HPS for around 500 Watts of LED (500W actual power) which would yield around 600 grams of dried buds.
Good fan-less LEDs run 1W or 3W LEDs and these lights can be situated mere inches above the canopy, however setting them at around 18 inches allows the lights to disperse the light over a larger area and gets better results.
The four LED grow light systems outlined below are all claimed to be full spectrum and are all around the 250W mark, taking into account the true Wattage rather than the total Wattage of the bulbs as explained earlier. Of the four, both the Black Dog BD-240-U and Super Grow’s SK450 can claim to be truly full spectrum, while the Hydro Grow’s Penetrator 168X Pro and Prosource’s Illuminator Pro target specific wavelengths.
The main difference between the Black Dog and the other systems, which may explain the lower price, is that the LEDs don’t have lenses or reflectors to collect and guide the light – reducing concentrated over the plants with a strong percentage of the light missing its’ target. To compensate, the lights need to be placed closer to the plants, reducing the effective growing area.
The Penetrator 168X Pro uses lenses that provide a beam angle of 60 degrees, which creates a more intense light over a relatively small area. The manufacturers also claim that their X2 lens system further increases the intensity, so more light will reach the bottom of the plants. One feature unique to the Penetrator 168X Pro is the switchable power settings from 0.5W to 1W to 3W. This is slightly misleading, as the unit is only designed to deliver just over 1.5W per LED at full power. Hydro Grow attempts to provide PAR data for the Penetrator 168X but if you visit their website you’ll see that is a graphical form that’s very difficult to interpret.
ProSource have opted for variable angled beams. This means, for example, that some may be set at 60 degrees, some at 90 degrees, and others at 120 degrees. The claim here is that this produces more illumination to the tops and the bottoms of the plants. This might allow for a slightly wider growing area but it’s not been proven it has any real advantage over single fixed angle beam.
Super Grow have opted for 90 degree lenses on the SK450 and this is perhaps the best compromise for maximizing the cropping area while maintaining a reasonably high light intensity. On a cost per sq ft of harvest area, the SK450 450 works out best value of the four lighting systems. If you need a larger growing area and are after a slightly more intense light, two SK450s can be bolted together. Super Grow’s spectral distribution data for this twin light arrangement is a very close match to natural daylight.
Based on the specifications, the SuperGrowLED SK450 looks like the best value. It produces a continuous spectral distribution that is close to daylight, it uses name brand LEDs, does not require an internal fan due to the impressive thermal management design and comes with 90 degree TIR lenses to concentrate the light on the plants.
Where space is limited or if you only want to grow a few plants, The Black Dog BD-240-U is worth considering, with what looks like a good spectral distribution and plenty of light.
If all you have space for is a single row of plants, due to its long, narrow geometry, the Penetrator 168X could be the ideal solution, but you may find it hard to justify the high set up cost.
The Illuminator Pro Hybrid 350W appears expensive with nothing special to offer. It has a fairly limited spectral distribution and we were slightly put off by the manufacturer not being open about true wattage. The spectral distribution may also be a bit restrictive, depending on what you want to grow.

The Future of LED Grow Lights
The commercial sector is really leading the way with LED grow lighting, making available a huge selection of lighting units. Although this is to be welcomed, the down side of it is that there are also many substandard products available that are not up to scratch and that will not produce the plentiful yields growers have become accustomed to with HIDs. They give the good LED grow lights a bad name.
If you do decide to invest in some LED grow lights it is important that you buy from a reputable source and be sure it’s somewhere that you can ask questions about the spectrum and light intensity of the unit. We can highly recommend working with Super Grow LED, they offer the best full spectrum LED grow lights we have seen anywhere. They are not just resellers, they are the manufacturers, they don’t sell junk, and they designed their products with the benefit of decades of LED lighting experience.
Big yields are obtainable using good LED grow lights noted by some of the leading Dutch growers who have already moved away from HID to purely LED based systems. One thing is for sure though, the technology is here right now and in a world where energy efficiency, heat reduction, space saving and sustainability is vital, LED grow light systems have a bright future for indoor marijuana cultivation.
