Hi J, Sorry so long to answer…..First i should correct myself and say that this is a production LED that we are tweaking to improve and not a “true” proto type. No real big secrets here. they have taken some very good designs and reversed engineered them and have improved certain aspects of the original. I actually did answer this on the lighting forum but couldn't upload my pictures and from the movement there which should be one of the biggest interests, it’s not, so i just dropped it. I so glad to hear that you know about LED spectrums, but not being a mind reader, its tough to know what you know and don’t know. It’s certainly no secret what spectrums are used by plants most effectively if you do the research even though most of the big name brand don't tell you what they are using. many add specific nm ranges that don't do any good for the plant but sounds like they will do better because they have 8 specific different nm leds instead of 4 or 5. It’s a bit more difficult for most people to know how to read spectrographs and how to analyze them or compare them to other bulbs spectrums. I do this for a living.
for reds, 430 and 470 and 630 and 660 for blue seem to do very well in research but its more the strength or power and lens design than the spectrum that makes the difference. if the nm range was shifted a bit on any 4 of these LED spectrums, i don’t think there would be much of a difference because there is an overlap on how the plant reacts to specific color ranges. but if the chips that drive the LEDs can handle more power without burning out and the lens (or in this case a secondary lens) has a better capacity to direct that energy and the thermal technology is more efficient so it can keep it all cool which is prime for longevity and consistent peak power, now you have something. This company designed 3W LEDs that are running at 700ma’s instead of the common 630ma’s with no overheating.
the 300wt light that i had tweaked is out performing my MH/HPS hybrid 1000wt HID using the very best soft start multi bridged electronic ballast and even I never expected that. I would have been happy if it just was comparable. I am having them add some IR to the next light as the plants that are getting a mixture of the 2 types of light are doing the best and only IR is missing from the spectral range that is used by plants in the LED light, but this LED is blowing away the HID as far as how the plants are reacting. the total LUX produced by this LED is higher than the HID, the plants show no sign of stretching or drifting and are a deeper green than the HID side. The IR is going to have a 120degree lens but I will keep the rest at the 90 degrees I have had installed on the first light because I have been informed that the IR LED they have is very strong and they feel we will get hot spots with a 90degree lens.
so the simple answer is that its not just "spectrum superior to most other LED lights" (although the spectrum we have is very good) it’s the power or light being delivered to the plants….and I will say that I never thought I would see the results I am seeing being a big 1000wt HID guy for 30+ years.
OH and I should mention that the retail price on this LED will be about ½ of comparable performing (if there are better performing LEDs) LED lights as I really am blown away by the results so far. But!!! We are still to see what happens in the flowering stage. The % I have is 2-1 red to blue, instead of the 8-1 most have as my experience in the past with HID has shown that I only needed one HPS to 2 MH for my clones to grow and flower at peak. 2 HPS to 1 MH was not anywhere near as productive and produced way more heat as the HPS has huge IR in its spectrum (all 1000wt). I have a MH bulb that has a spectrum so complete that it over shadows the red side of HPS but the company has only developed it in 400wt write now. I hope to see it in 600wt soon.
