The Fenix HL55 headlamp offers four brightness levels plus 900-lumen burst mode and 150-hour runtime from one 18650 battery or two CR123A batteries. Neutral white light means superior definition and penetration in high-humidity environments. A 116-meter carry distance reaches farther while the side switch on the head is all you need for ON/OFF, output selection and burst. With all-metal housing and ANSI rated, the HL55 matches all-season backcountry and cave exploration.
