Hi everyone. I know virtually nothing about flashlights but I know a lot of you guys have the flashlight bug like we all have the knife bug so hopefully you can help me out. I want something he can carry with him (or at least keep nearby) all the time so maybe 3" long or so? Wicked bright, lithium power, etc. He usually has a D cell Maglite but my baby brother is always misplacing them (how can babies lose such big things??? wtf?) so I want to get him a nice light he can keep on him to blow the Maglite out of the water. Budget of 100-150 I guess? Thanks!
