Fenix HM65R-DT Trail Running Headlamp | 1500 Lumens, Warm White, Magnesium

1500 Lumens. Warm White. Built for Endurance.

The Fenix HM65R-DT is a top-end trail running headlamp engineered for endurance athletes who spend hours in the dark. It delivers 1,500 lumens through a 3000K warm white LED — a deliberate choice over cool white. Warm light reduces eye fatigue on long runs, improves contrast on uneven terrain, and feels more natural to the eye over multi-hour efforts. Paired with a 560-foot (170m) beam distance and a lightweight magnesium alloy body, the HM65R-DT is built to perform from the first mile to the last.

3000K Warm White LED: Less Fatigue, Better Contrast

Most headlamps use cool white LEDs (5000K+) that maximize raw lumen output but cause eye strain over long efforts. The HM65R-DT's 3000K warm white produces a softer, more natural light that reduces fatigue during night ultras, multi-hour training runs, and pre-dawn starts — while still delivering 1,500 lumens of output when you need it.

560-Foot Beam Distance

At 560 feet (170 meters), the HM65R-DT throws significantly further than most trail running headlamps — giving fast runners the reaction time they need on technical descents and winding singletrack.

Single-Handed SPORT Fit System

The SPORT fit system allows full headband adjustment with one hand — no stopping, no fumbling. Tighten or loosen mid-run without breaking stride. The perforated headband promotes airflow and reduces heat buildup during high-intensity efforts, keeping the light comfortable over long distances.

Magnesium Alloy Body

The same magnesium alloy construction found in the HM62-T — delivering aluminum-level durability at significantly less weight. Every gram saved on your head translates to less fatigue over a long run.

Extreme Temperature Range

Rated to operate from -35°C (-95°F) to 45°C (113°F) — reliable in winter trail conditions, alpine environments, and desert heat where standard headlamps fail.

Available in 3 Colors

Choose from Black, Dark Purple, or Nebula — same performance, your choice of finish.
