My new ozark trail headlamp has high and low, 220 and 22 lumen. PLUS it has S-0-S mode. It's pretty nice I think, and I like the swivel head that lets it go from an angle light (the headlamp part) or a conventional straight tube light. It's supposed to burn for an hour on high and 10 on low. SOS is high power.
