This is the headlight I have, it's coast HL8, the same as a model that LED Lensar (that's owned by leatherman) sells. Coast makes it for them.

If you don't mind battery pack - it's amazing. 4 other people at work have bought this light after seeing mine work at night. They make a rechargable model, called the HL8R
They both have 3 levels of output, and a focusing lens. At full flood - the light is totally bright and even.. The pack is detachable and you can wear it on a belt.. It's not a small light, but it's a VERY good one, and has long run times.. You might want something smaller, but I can promise you this one is great if you are ok with the size.
I get some model of steam light headlamps at work.. They retail for like $25, and the model work provides *****.. It's just a spot light - with a small annoying bright spot in the center like a flashlight from 1980. I'm sure the better models aren't like that, but I'd never give up my coast.
