Fenix HM65R-T Review
The Fenix HM65R-T pairs a 1500-lumen spot-and-flood setup with a magnesium body and 18650 battery. It's a strong night-running light that weighs too much for most ultralight kits.
Overview
The Fenix HM65R-T is a rechargeable trail-running headlamp with two separately switched LEDs, a magnesium alloy body and a Boa-style rotary headband. It is built for people who run or hike fast in the dark and want real throw. The trade-off is weight: the lamp is light for its output, but the full kit with battery and band is a long way from a 2-ounce ultralight headlamp.

Performance
Light. The HM65R-T’s party trick is its two-emitter layout. The spot LED does the long-range work, while the flood fills in the foreground. Each has its own top-mounted switch and its own three levels. On technical singletrack, that means a low flood for cruising and a bump of spot when the trail turns rooty or a trail marker needs finding. Reviewers at Believe in the Run praised the control this gives for budgeting battery over a long night. Trail and Ultra Running’s tester called the 400-lumen middle spot setting plenty for running through the night in an ultra.
Runtime. Fenix rates the top spot mode at 4 hours, and testers say that figure comes with caveats. Believe in the Run reported that full output holds for roughly 90 minutes to 2 hours before it starts to fade. Trail and Ultra Running’s tester saw closer to 3.5 hours at maximum. The medium levels are where the numbers get honest: 400 lumens on the spot is rated at 12 hours, and that figure held up in testing. Owners say the low flood setting lasts for days of camp and around-the-house use, and the 130-lumen spot mode is rated for 24 hours. The lowest flood mode, at 5 lumens, stretches to 300 hours.
Fit. The headband is the other reason owners rave. It’s a wide, multi-layer mesh and elastic band with a rotary dial at the back. Pull the dial out to loosen, push in and turn to tighten, all one-handed and mid-stride. Believe in the Run likened it to wearing a sweatband rather than a headlamp. Owners with larger heads report the band reaches its limit when fully extended.
Weight. This is the catch. The 91 g figure excludes the battery. Believe in the Run weighed the full package at 4.9 oz, more than an ounce heavier than a Petzl Swift RL. Much of the mass sits in the metal head and the 18650 cell, and some users note the lamp feels solid rather than featherweight. For trail running, where the band sits snug and bounce-free, that’s tolerable. For a thru-hiker counting grams, it isn’t.
Durability. IP68 sealing and 2 m impact resistance put it in the tough-by-design category. Owners describe a rigid, tool-like body, and a maintenance worker who used one around mud, grease and sweat reported no complaints. A spare O-ring ships in the box.
Power. The 18650 format is a genuine plus. The cell charges in-lamp over USB-C, but a spare cell can be swapped in on the trail, and two CR123A batteries work as an emergency backup. A battery indicator shows charge state.
Pros & Cons
Pros
- Independent spot and flood LEDs, each with three levels
- Up to 1,500 lumens and 170 m of throw
- Wide, comfortable rotary headband that stays put while running
- Replaceable 18650 battery, CR123A backup, USB-C charging
- IP68 and 2 m impact rating in a magnesium alloy body
- Medium modes deliver long, dependable runtimes
Cons
- About 4.9 oz with battery and band, heavy next to ultralight headlamps
- Max output fades well before the rated 4 hours
- No red or night-vision mode
- Some owners find the wide flood beam less useful than the spot
- Larger heads may max out the band’s adjustment
Who Should Buy This
Trail runners, night hikers and ultra racers who want a bright, reliable light and don’t mind carrying a few extra ounces will like it. It also suits hikers on winter trips with long dark hours, where a swappable 18650 and big runtime margins matter more than grams. Thru-hikers who mostly use a light for camp chores and short pre-dawn starts should look elsewhere. A lamp in the 40 to 70 g range with a 300 to 500 lumen ceiling will do that work and spare the weight.
Note that Fenix has since released a V2.0, which swaps the spot-and-flood arrangement for cool white and warm white emitters and adds a whistle to the headband. Shoppers wanting the dual spot-and-flood layout described here should check which version they are buying.
Verdict
The HM65R-T is a bright, tough, comfortable night-running lamp with an unusually flexible two-beam design and a battery that can be swapped in the field. It is not an ultralight headlamp, and anyone shaving grams will feel the difference. For runners and fast-and-light night movers, it earns its place; for the average thru-hiker, it’s overkill.
