If you haven't dealt with high-power LEDs, I can tell you that they are 
very hot. The reason all high-power LED flashlights are aluminum is to 
act as a heatsink. The whole body of the lights can get up to over 
100°F, and that's just for a couple hundred lumens.

Also, the price of LED, even when factoring in its long life, is still 
much higher than HID or fluorescent. The technology will mature 
eventually, but it's not there yet.
