If you have an infrared camera, especially those mediated reality POV goggles we previously wrote about, this handheld spotlight is a must have. Perfect for hunters, assassins, and snoops, the $150, the 1-million candlepower is a bargain. I also can see the military using something very similar in conjunction with their night vision goggles, if they don't already.
If I can get an infrared camera this summer, I may well buy one of these for the wifi technomad geekery at burning man.
