Powerful, versatile, eats batteries
The halogen bulb on this thing is pretty sweet for lighting something in the distance and the 5 LEDs can make it seem like nearly daylight in your immediate surroundings. My roommate got one and I borrowed it on a remote bouldering trip and I wish I could afford one. It seems heavy but it isn't bad at all one you got it on your head. Luckily it uses AAs too because he says it didn't last as long as he had hoped. Also he claims the case is waterproof but I'm not about to jump in the river with it on quite yet.
