Fenix HM71R Headlamp — Universal Light Source for Camping and Work
The Fenix HM71R headlamp from the Fenix brand is designed for use in industrial settings as well as during outdoor activities. Product category: Camping & Tourism > Camping > Camping Lanterns. The model combines a long-range and diffused beam, providing a maximum brightness of up to 2700 lumens and the ability to illuminate objects at a distance of about 230 meters. The stated battery life in some modes reaches 16 days, making the device a reliable companion for long hikes or during emergency situations.
LEDs and Optical Characteristics
The Fenix HM71R uses two Luminus LEDs: SFT70 with cool white light at 6000K and SST20 with neutral white light at 4000K. This combination allows for both a narrow, long-range beam and wide, eye-friendly close-range illumination.
Operating Modes
The interface consists of two groups of modes — for long-range and close-range light, with four modes in each group. The technical specifications for each mode are listed below.
Long-Range Light
- Turbo: 2700 lumens / 13300 candelas / 230 meters / 3 hours;
- High: 800 lumens / 2705 candelas / 104 meters / 5 hours;
- Med: 200 lumens / 686 candelas / 52 meters / 16 hours;
- Low: 50 lumens / 181 candelas / 27 meters / 48 hours.
Close-Range Light
- High: 500 lumens / 555 candelas / 47 meters / 8 hours;
- Med: 200 lumens / 225 candelas / 30 meters / 16 hours;
- Low: 50 lumens / 50 candelas / 14 meters / 48 hours;
- Read: 5 lumens / 6 candelas / 5 meters / 400 hours.
The Read mode provides the lowest, but eye-comfortable brightness — ideal illumination in a tent or room.
Control and Additional Features
The model is equipped with a single large textured switch on the body, which is easily located even with gloves on. An electronic lockout function is present to prevent accidental activation: holding the button for 3 seconds activates or deactivates the lockout. The switch includes a colored battery level indicator.
Power Source and Charging
Powered by a 21700 form-factor lithium-ion battery — ARB-L21 (5000 mAh) manufactured by Fenix. Operating voltage — 3.7 V. Using batteries from other brands is not recommended, as it may prevent Turbo mode activation and lead to device damage. A USB Type-C cable for charging is included; a full charging cycle for the proprietary battery takes approximately 4 hours, during which the indicator in the button displays the charge status.
Materials and Construction
The body combines 316 stainless steel in the head section and anodized A6061-T6 aluminum alloy in the body, ensuring enhanced durability and electronics protection. The new headlamp mounting system has eliminated protruding plastic holders: the flashlight is secured to an elastic band with a steel clip — this reduced the weight of the structure to 207.5 g and simplified installation and removal.
Without the headlamp mount, the HM71R transforms into a portable flashlight that can be used as a handheld light, a chest-mounted model, or as a work light — the body is equipped with a powerful magnet for attachment to metal surfaces.
Dimensions, Protection, and Completeness
Dimensions: 106 x 46 x 45 mm. Ingress protection rating against moisture and dust — IP68. Impact resistance is stated for drops from a height of up to 2 meters. The set includes: the Fenix HM71R flashlight itself, a warranty card, instructions, a spare O-ring, a 21700/5000 mAh lithium-ion battery, and a USB Type-C charging cable.
