Yeah but they are $88 a piece, at least for the copper ones, which may also dissipate more heat.
Hope someone builds some and does a thread. Could be the simplest solution yet.
I don't doubt that high wattage LEDs work. CPU coolers would cool them, but they are clunky, heavy and sometimes very sharp, not to mention expensive.
At least one of the datasheets I read showed them with a 60 or 90 degree beam angle, which could burn if too close.
The reason people aren't crazy over them is that there are no results, really. Show me an amazing grow bursting at the seams with dank buds and I will be first in line.
I wouldn't be the first. There's a couple guys over on RIU who are vegging with LED flood lights with very good results. One of them has contacted a Chinese manufacturer about a custom spectrum multichip LED.I'm with you Weed--I needed to see a completed grow using a similar light to mine before I took the plunge. Hopefully others are inspired after seeing the good results from LED grows here.
Why not be the first using high watt chips??

Killkingkong: Hey, I think you should hold off on that CPU cooler, I just emailed the manufacturer about thermal resistances at various fan RPM's and asked what the current should be for those RPM's. That CPU cooler says it only has two heat pipes which honestly doesn't sound like a lot for 100W, imo, I'm guessing 50-70W max on that one. Then again, Idk how efficient those Cree's are, so maybe they'd only be sending 50-70W of heat into the CPU cooler? Idk, but it's close, imo.
There's lots of good stuff for pretty cheap on eBay. Hell, I got my SuperMicro for $17.50 SHIPPED and temps stay ruler flat with a 50W on it (could probably cool a 100W). Awesome buy, imo, and I got it... on eBay.
