I used to have a maglite, but it broke a little bit ago. I want to replace it with a decent model that'll last at least as long. Preferably it would fit in a bob or something I could carry on belt in a sheath, or clipped. And preferably either water proof, or durable.

I'd like to get decent battery life, or at least easily changeable battery (standard size) and a reasonable output. What are the main differences on the bulbs? How many should there be? (A cheapo 6 led I have now has a good output but is neither durable or waterproof)
