Comments about Princeton Tec Yukon HL Headlamp - Black:

Too many headlamps now use utterly useless AAA batteries. This one uses AA which last MUCH longer and are used for many other devices I also own.
Long beam option is good for motion activities like skiing and sledding.
Caution: as with any battery device, avoid using Duracell AA which are more prone to leakage than any other battery in my experience. I have had two sets of these headlamps destroyed by the dreaded coppertop batteries. Nice that Princeton TEC includes a set of Duracells but do yourself a favor and dont use them.
