The Snap-on Camo Enduro LED Headlamp, No. STL61405, is powered by two AAA batteries to create C4 LED high and low modes up to 50 lumens and lasts more than five hours. On the low setting of 10 lumens, this impact-resistant headlamp will run 25 hours, and all of that light is packed in a drop-tested housing, says the company.
