All of my gadgets take AA batteries EXCEPT my headlamp. This is a Tactikka + (the 4 LED unit and not the 3 LED POS with the slide switch) which takes AAAs. I am eyeballing the Petzl Myo XP that takes AAs and the Surefire one with the rheostat. The problem with the Surefire one is it has the 123 lithiums that are not the same.
