You can rely on Fenix's HL25 Headlamp during the hard, dirty work involved with caving, climbing, dawn patrolling, mountaineering, and paddling. Its rugged alloy housing fends off impacts, water, and all that dirt. Fenix added an anodized coating for extra resistance against abrasion, and the glass lens has an anti reflective finish so you can get the most out of the headlamp's light. Cree XP G2 LEDs brighten everything up to 200 feet, and the included batteries provide lighting up to 140 hours. An intelligent memory circuit remembers your preferred brightness levels, and the digitally regulated output maintains a constant brightness.
