The BLACKSTAR line uses 2w and 3w chipsets, delivering the most powerful LED's in the world. Penetration of the canopy is unmatched, we use a combination of 60deg LED's and 120deg LED's for the perfect ballance between penetrating power and coverage area.
There are now the optimum balance of spectrums for flowering. The majority of the LED's are 630nm and 660nm but this light also has 730nm infrared, 380 Ultraviolet, 425nm deep blue, 12,000k Cree(with 450nm peak) white chipsets. This light can be used from start to finish during a grow but they are especially useful for flowering. Our grow tests and reviews from shops and customers tell us that due to the huge red wavelength concentration, flowering is induced several weeks earlier using this light. If you are looking for a light just to be used in Veg/Clone, take a look at our High Output series.

HYDROPONIC LED 101 ï¿½ Please Read
* Why buy from the USA? Buyer beware, buy from China and wait up to 5 weeks for shipping, and if and when the light is defective, you must pay to ship back to China to claim warranty (if any).
* Never buy from any company you can not talk to. 1800-607-2516 We are not just an Internet company selling products we do not know anything about. We are a brick and mortar Hydro distributor, call us and find out.
* I see ads for 5band, 6band and more bands, why would I want a 2-3 band LED? More bands does not mean a better light, these spectrums are the most efficient and proven wavelenghts for flowering. We sell a 6-band also, but for flowering, this is the best light we have tried.
* I live in Europe, will this light work here? Worldwide voltage, no import tax, UK plugs available, we have locations in the UK and Australia!
* Why are you the best company to order this from? With over 6000 satisfied customers and 100% feedback, we pride ourselves on customer service and providing the best Hydroponic equipment in the business. Just google us on the forums!
* How Many Plants will this light cover? We do not exaggerate any claims. Coverage is limited by the physical size of the unit. Our suggested coverage for this light is about 12 sq. ft. Any 500w LED light claiming to cover more area means the seller does not know what they are talking about.
* How does this light compare with HID lighting performance? We sell HID lighting too, so there is no use in us claiming anything that is not 100% sure. LED lights are more money up front, but you save on Electric consumption, cooling costs (which are huge) and bulb replacement. The typical error made is that people do not use enough LEDs. With enough lighting, these 2w LEDs will produce a great yield. Typically 10% less than a comparable HID system but with faster tomato flowering and lowered operational costs. If you are not with your grow, I personally do not like the idea of an HID light burning unattended.
* Does this light put off much heat? Not at all, you can actually let the plant touch the light, although it's not suggested.
* What makes this LED different than others here? Simply put they use better LEDs and are a reliable company. It's just like using a Chinese HPS bulb vs spending the money on a Hortilux bulb. You get what you pay for, this is the only LED we sell in our storefront because it is the only one that has proven its success.
Not all light is created equally. And neither are LED lights! At least not as far as plants are concerned. After discussing this matter with a few PHD professors at Cornell University, we were directed to a few studies. Below is an accurate chart of light spectrum usage by plants.
Details can be found at http://course1.winona.edu/sberg/308s05/Lec-note/15-new.htm
What does this mean for the indoor grower? This is the wavelength spectrum of white light that plants use. So how does this affect our analysis of HID lights? Below are the light output spectrums of the most popular HPS and MH lights in the market.
The graphs speak for themselves. Neither HPS nor MH provide much lumen output under 580nm. This means that the largest portion of lights used by plants 420nm-455nm is not supplied by either light solution. The peak lumen output is 580nm, 595nm & 615nm. As you can see, that translates into a loss of about 83% efficiency when overlaid with the light used by growing plants. Thus, a 40,000 400W HPS bulb translates into 6800 actual usable lumens. These charts are available from the manufacturers and widely distributed, touting that they are closest to the natural light output of the sun. Thing is, plant's don't use all of the sun.
There are mitigating factors. Our friends at Cornell have informed us that a healthy plant gets the most vegetative boost from blue and ultra-violet wavelengths. We have long known this in the industry because traditional success dictated that vegetative growth is done under MH lights (more blue) and flowering is done under HPS (Red) lights. The later in leaf diameter is outlined in the study attached below:
The final analysis is that the most successful growth is found at 420nm, 450nm, 630nm and 660nm wavelengths. There are ideally 4 peaks of growth spectrum. Red is slightly more important for flowering but blue produces faster growth and absorption. It is also important for plants to get more 600nm-630nm wavelengths because it is reported that those wavelengths determine leaf diameter. Larger leaves will make a larger plant. And who doesn't love a big tomato plant! Larger leaves lead to larger surface area for further absorption, etc, etc.
Since LED's produce a fairly uniform output +/- 10nm we concluded that given the correct wavelengths, LED's could possible do the job if they lumen output was great enough and they had the correct spectrum.
In our 2009 LED Growlight Showdown, our winner (Black Star LED) employed a unique LED. After our analysis, we concluded that the reason for the win was the use of a mixture of 630nm UV/Blue LED's rather than the traditional blue 660nm LED's used in all other LED systems tested. This is confirmed from the spectrum usage graphs above.
So in usable lumens we have the 5010 lumen 90w LED from Lighthouse Hydro vs the 400w 6800 lumens of a Sun Agro bulb.
LED= 43 usable lumens / watt HID = 17 usable lumens / watt
Yes, the LED is superior but based on lumens/watt alone a 90w total output is not equivalent to a 400w HID light.
On Lumen output alone, a 90w LED does not match the 400 HID light system. In usable lumens alone the conversion is more like 90w LED = 320w HID (HPS/MH)
