Expensive but worth every penny
May 9, 2014
This head lamp will operate on one, two, or three CR 123 batteries, or two AA. It was this versatility that led me to it in the first place. You can remove the battery pack and just use one 123 battery to greatly lighten the weight. VERY WELL MADE, as are all of Surefire products. It can be infinitely adjusted from 1 to 100 lumens, and that is plenty to walk and function in a dark environment. I usually turn mine down to conserve battery life, especially when I get settled in. It's aluminum, very solid, so it is a little heavy for backpacking if you carry the whole kit, but should last a lifetime.
Also, Battery Junction has the best price around!
