Hi there.
Looking at getting myself one of these:
http://www.zebralight.com/H501-Headlamp ... _p_11.html
Including a lithium AA battery, comes to less than 60 grams!
I've had enough of headlamps requiring 3 AAAs (because then I need three spares), or cheap/heavy lights, and this one seems to have 3.5 days continuous use on a single AA at the light level I use.
I've found a lot of information on candlepowerforums.com, but does anyone on BWT have any experience with their products?
Cheers
