The selling point of all this, or even the basic point of interest here is plants. I think this is being sidetracked on R&D, how LEDs work, how wattage/voltage works, etc. I read through the whole thing because I'm interested in scientific trivia but quite frankly you likely lost readers on page 2 or 3.
Here's the rub man, if you light will veg/flower like a 1.5k watt HPS/MH and only use a fraction of the electricity that's heat free?
Yes, but not completely heat free.
Hell yeah I'm in, sign me up, I'll order several. However I don't care how advanced the technology is, it could even make me breakfast with coffee in the morning - I won't care about a growlight that isn't PROVEN to have advantages over what I'm using now.
OK, agree completely.
I feel that a test of 7 lights vs one light won't work.
This 7 to 1 ratio crap isn't from me..?
I'm not looking to spend $7,000 on a setup that does the same thing as a $300 but uses less power. The idea is ludicrous, your light costs a small fortune. However if I hear that I can spend a thousand bucks on a heat-free light that uses 1/10th of the electricity with identical results? Thats an upgrade I may consider to expand setups with reduced overhead.
Bottom Lines:
1000W with a fraction being the right colors, true power to the lamp is only 8.6 Amps.
287.5 W with ALL of the 11.2 Amps powering the right colors (wavelenngths)
You can add me to a mailing list on RIU if you have something like that to sell your product, however I will not be interested until you have 3rd party test results saying "This performs equal or better to a 1,000 watt HID system. Good luck, hope this is a successful product. It would definitely aid in growers in having larger operations at a lower profile.
