For the last numerous years I've made do with a couple of Energizer branded* el-cheapo headlamps ($18ish) and so far I've done a whopping 3 battery replacements in them. THey seem to last forever but don't cast a lot of light.

I'm thinking of upgrading to the Fenix HP15 which has a remote battery pack but a heck of a lot more power and flexibility than what I have now. Mine are just getting old enough that the rubber switch cover is starting to wear thin, the angle adjuster isn't quite holding anymore, etc. 6+ years of frequent use (home, working on the car, camping, etc) for around $18? I think I got my 3 bucks a year out of them. I thought they were decent until I camped with some guys that had more recent ones. Granted, I don't need $150 headlamps like they have but a nice upgrade would not go astray.

The Fenix I'm looking at has a street price around $65 which isn't bad for the next many years.
