Have to admit I often find myself hiking and especially setting up camp after dark, and today's headlamps really make the whole thing possible. So no, I won't leave mine at home. My current favorite is the Tikka XP but I'm eyeballing the new Primus 2xAAA cell lights, in case they're ever imported to the States.

Considering what I once carried today's LED headlamps are nearly weightless and are unbelievably dependable, plus being very frugal with batteries.

As much as I love button cell lights they're so poor WRT battery life they're really only good for emergencies and puttering around camp.

Cheers,
