Okay, since I'm still waiting for the drivers for the larger chips I decided to start working on the smaller 50W lights. So today I set up a small test using an Arctic Cooling L2pro cooler with a 50W 10K multichip on it. I'm driving the fan with a small 12V poweradaptor. Nothing is soldered or set up properly as I'm only testing the cooling capabilities. As suspected, the cooler rated at 100W has no problem keeping the LED cool.
So a complete 50W LED light for about 110 dollars.
Btw, the pictures might not look like much, but I asure you guys, this LED sure packs a punch.
The test setup, scissors included for size reference.
Everything fired up. Had to take the picture from the side, my camera just could'nt handle the flare from the light.
