With few exceptions, like a helmet-mounted carbide lamp and electrical version for wet caves, I've generally avoided dedicated headlamps because they tend to be blocky, and bulky, and always in the way when you aren't wearing them. Instead, for kit use I've gone to small flashlights and used a Nite-Ize headband to hold them on the side of my head. Works pretty well. I have the compact and easy hand-use of a small flashlight and the hands-free use of a headlamp without the typical bulk.

That Energizer "Outdoor" unit might be small and compact enough to make me reconsider. The price is right up may alley also. I'd still need to look closely at it, knock it around a bit, maybe take one apart, to see if I'm getting a unit punching well over its weight for value and cost, or an overpriced paperweight.
