The above recommended LED plates look great. But the HEAT SINKS cost more than the plates. Thirty bucks for a 10 watt plate and heat sink is a little hard to take. Then, they want shipping and some want tax. All I want to do is get a white LED that puts out as much light as a 26 watt white G.E. CFL. This is getting nuts :(
A chunk of aluminum or copper sheet will work as a heat sink, at the worst but still useful a piece of steel can be used. Basically most metals can be used as a heatsink, some work better than others.
I simply took a piece of 1/16 thick aluminum about 3x4 inches and bolted the chip to that (use some silicone heatsink compound between the two). The chip has two small holes which I tapped out and used a couple of machine threaded screws I had laying around.
If you want to go insane, they do have a 100W LED chip, but you would need a DC-DC switcher to take 12V up to 32V. That one would light up your entire RV and most likely would look like you are welding...
Can't say how they will hold up but I personally plan to under drive them for best life. Just something these clowns just don't understand, they take 20 or 30 fractional watt LEDs then drive them at the very top edge of the max ratings. It is no wonder that folks get spotty life results...
