I am thrilled with my Arc AAA, which is not a headlamp, but with a clip from a AAA Mag Light, I clip it to my baseball cap, which I always have when outdoors for any period of time (bald head). This system is much more versatile to me than a dedicated headlamp, which always seemed a bit cumbersome to me. With my light, I can use it as a standard hand held light, plus it's so small with its single AAA battery that it fits in the smallest pocket or kit. It's very bright, enough for just about any of my needs, and built super tough.
