Hello folks
I know a lot of people are interested in LED growlights. Quite frankly, the manufacturers are ripping us off with grossly inflated prices, such as 600 dollars for the 90W UFO, you could build a much better light for 200 dollars.
The problem is always drivers, they are expensive, but I have found a wonderful cheap unit for just under 17 dollars with shipping, they are 47.5W, the output is a whopping 68V at 700mA so it's perfect for driving 3W emitters.

I've bought three of them and built a 150W LED array using CREE LEDs, and you can pick up 3W LEDs from as little as 3 dollars now, so don't waste thousands of dollars of UFOs, procyons etc, get the soldering iron out. I'll be posting details of my light shortly. I'm gonna be running my 150W LED array in the 2x2 tent I won, I am hoping I can get a decent result this time.
These Luxeon K2 warm white LED stars are excellent for growing, having plenty of red in their output spectrum but with a blue spike that corresponds exactly with the response spike in that region. Only 3 dollars:
Luxeon 3W red bare emitters are only just over 2 dollars:
Same supplier does the cheapest 3W UV emitter too but it's 8 dollars:
So grab yourself three 50W drivers, 75 red LEDs and 25 warm white LEDs and build yourself a kickass UFO killer for 300 bucks, for heatsinks, be creative, find somethign aluminium.
For sticking it all together this thermal glue for 8 bucks is awesome:
150W for 300 bucks sounds a lot better than a 90W UFO for over 600. 2 dollars per watt is as cheap as you are gonna get for LED grow lighting currently, trust me, I've done countless hours of research into the LED market.
