I think you will really like the array design im thinking. cover the entire surface of one of these heatsinks Bonded Fin/ Standard Parts with the luxeon rebels (only 3mm*4.5mm[13.5mm^2], 0.12"*0.18") and the LedEngin 10W and 15W LEDs(both 7mm* 7mm, 49mm^2). I was thinking of using one of those heatsinks with a width*length*height of 305 mm*371mm*152mm (12"*14.59"*6") , thats 113,155mm^2 cooling area with dual 100cfm fans. on that 113,155m^2 we could fit 8000 luxeon rebel LEDs or 2000 10W LedEngin LEDs!!!!:rastasmoke::rasta::thumbsup::wtf::hippywith proper ventilation and cooling). the °C/W rating is .028°C/W, so for it to get 28°C hotter than it would have to receive 1000W of heat energy from the LEDs, voltage regulators, whatever needs to be cooled.

and maybe once i get some funds we could use water cooling systems (like this radio shack one but on a larger scale[will be much cheaper to make]) RadioShack.com - Computers: Components & parts: Cooling systems: Bigwater 735 Liquid Cooling System

LED growing- An instructional grow log trying this again. growing jack herer x bubbleberry in pure LED. these plants wont see any white light from seed to bud. tried posting pics once...so here we go again. questions or comments gladly answered. Dont think its been done quite like this before. ;) wish me luck! whiskeytango SnSstealth Rating: 5
