I used to scoff at headlamps in general. The LED battery life made me a convert. Question about that. Mine has a high and low beam option. The way they do that is by making my low beam flash at a high (ok, maybe low ~50 times a second) interval. The dim setting took some getting used to.

What I dislike overall about wearing headlamps is there is little depth perception at that angle for walking around. Hold it in your hand and you see a whole new world - w/ a lot less surprises to trip over.
