>>470182I just got a Fenix HL50 headlamp.
>made of aluminium>somewhat waterproof>detachabe from head band>uses a single AA battery (or CR123A if that's what you want)>3 modes: 155/50/3 lumens with AA Ni-Mh>remembers the last used modeYou get more power and runtime with CR123A, but I'm planning to use mine with regular AAs.
I hate to recommend anything made in China, but this headlamp is best I've ever seen.
