After laying it out thoroughly in CAD, I will not be able to cover enough space left to right. I would have to really make a light consisting of 5 pieces. A center piece and four "islands". One in each corner.

I figured a 90 degree beam spread at 6" above the plants. Making it a 1' diameter footprint per LED. It would take 13 red LED's to cover a 3'x3' space leaving little room to waste. There would be three reds on each island and one red and two blues on the center piece.

I'd need to use 5 fans, one for each sink, but they are cheap. In my head it's kind of like a chandelier.....

Anyone have any feedback on my idea? Is there an easier/better way to accomplish lighting a 3'sq. area?
ledtime Reviewed by ledtime on . Calling out to Weezard for LED advice My friend, I've read your stuff here and at Steve F.'s site. I want to build a dedicated flowering lamp using Ledengin 15 watters. (4 reds, 1 blue, and possibly 1 warm white; LM 317's so I can tweak the ratios.) Essentially, a copy of your 4+1 cake pan lamp but built on a 4 x 18" finned heatsink so I can see what's going on under it.) If I were to post my picks for power supply, resistor ratings / values, etc., would you critique and perhaps offer some guidance? I have already purchased Rating: 5
