Well i am no engineer so how you go about powering all the leds and cooling them properly is beyond me, but the proper functioning of the LEDs and their lifespan requires that they be properly cooled so you will need to figure that out otherwise you won't get the full theoretical light output...
Sorry just another point. If you are buying led don't forget to calculate the total cost to run it versus hps or something else.
If you buy a led like the procyon or the smartlamp, they are expensive to buy up front but pay back pretty quick in power savings in somewhere between one year and...
I definitely second the info on the Smartlamp. I use it now and am totally happy.
You have to really be careful when you come across inexpensive led lights -- if the light is less than a procyon or say less than two or three hundred bucks it is going to be low power leds. What does that mean...
Has anyone tried this LED grow light called the SmartLamp from a company called Theoreme Innovation ?

I need something more serious than the little lights that are all over the web and this would seem to be it but i would like to know if anyone has used it.
