Oh geez people I KNOW HPS IS THE SHIT, but its hot, expensive, and bad for the enviroment. These LEDs concentrate on lumens, not light. They are specificaly designed to be stronger in the blue and red spectrums. I am simply seeing how well they work, and posting the progess, because no one has posted anyhing they have tried since 2006. I think some technology is worth a shot if it is new, or redesigned. Believe what you want, I got the pics, and I will post updates. The true test is going to be the quality of the smoke. I should let you know in about 6 or 7 weeks
