Fenix HM62-T Lightweight Trail Running Headlamp

The Fenix HM62-T is a lightweight, high-performance trail running headlamp built around a magnesium alloy body, offering up to 1200 lumens with IP68 waterproofing.

Shopi's verdict

The HM62-T is a serious ultrarunning headlamp that punches above its weight class — 1200 lumens and IP68 waterproofing in a magnesium-bodied package light enough to forget you're wearing it on long efforts. The main trade-off is that high-output modes will drain the battery faster, so ultra-distance runners should plan around lower brightness settings to maximize runtime. A strong pick for trail and ultra runners who refuse to compromise on weather protection or weight; casual hikers may find it more headlamp than they need.

### Overview

The HM62-T is built around a lightweight magnesium body that is 30% lighter than aluminum, making it one of the more thoughtfully engineered headlamps in its class for runners who feel every gram. It delivers 1,200 lumens of output, illuminates up to 150 meters, and offers up to 23.7 hours of maximum runtime — a runtime profile designed with long-distance and overnight efforts in mind. It retails for $75.95, placing it in the mid-range tier where performance-per-dollar is genuinely competitive.

### Pros

- **Verified ultramarathon-ready runtime:** At High mode (400 lumens), runtime stretches to 12 hours, and at Medium (130 lumens) you get 23.6 hours — enough to cover most 100-mile night segments on a single charge without swapping batteries. - **Dial-adjust headband that works mid-run:** The headband is perforated and two-way adjustable, allowing users to adjust it with one hand while on the run — a practical detail that matters when you're descending technical terrain and can't stop to fiddle. - **Battery flexibility for remote races:** The included USB-C rechargeable 18650 battery is also compatible with CR123A batteries, so if your power bank dies mid-race, you can grab disposables at a gas station or aid station and keep going. - **Glove-operable controls with a lock:** A large glove-friendly switch handles all modes, and an electronic lock prevents accidental activation during storage or transport — useful for winter races and for tossing the lamp in a drop bag without it draining.

### Cons

- **No onboard charging on the headlamp itself:** There is no onboard charging built into the lamp unit — it's only a drawback if you like to swap cells with standard batteries, in which case you'll need button-top cells and a separate battery charger. - **Single-beam design (no flood/spot combo):** Unlike dual-beam headlamps that offer both a wide flood and a focused throw, the HM62-T uses a single Luminus SST40 LED — runners who want a wide peripheral flood for technical trails may find the beam pattern limiting. - **Press-and-hold UI:** The on/off requires a press-and-hold, and switching to red light requires a double-click — a minor but real friction point when you need to react quickly in the dark.

### Who It's For

This headlamp is purpose-built for trail runners and ultramarathon athletes who need a reliable, lightweight lamp that won't fatigue the neck or bounce during long efforts. It has been used in events like the Kettle 100 ultra, and its runtime tiers make it practical for both fast-and-light training runs and multi-hour overnight race segments. IP68 waterproofing and 2-meter drop resistance also make it a solid pick for mountain hikers and alpinists who run in unpredictable weather.

### Not Right For

Runners or cyclists who want a dual-beam (flood + spot) headlamp for wide peripheral coverage on technical singletrack — a lamp like the Fenix HL32R-T or similar dual-LED designs would serve that use case better.

A serious ultrarunner's headlamp that doesn't ask you to choose between brightness and weight.

What stands out

  • 1200-lumen peak output delivers strong illumination on technical night trails
  • IP68 waterproofing means it holds up in sustained rain and stream crossings
  • Magnesium alloy construction keeps weight low without sacrificing durability
  • Long runtime modes make it viable for extended ultra-distance efforts

What to weigh

  • Maximum brightness modes will drain the battery faster, requiring a power bank or spare cell for very long events
  • Magnesium body, while light, can be more susceptible to denting than polycarbonate alternatives
  • Premium construction typically places it at the higher end of the headlamp price range

Great fit if

  • Trail and ultramarathon runners who need reliable light through long night sections
  • Runners who race or train in wet conditions and need genuine waterproofing
  • Athletes prioritising a low-weight kit without dropping to budget-tier hardware

Skip it if

  • Casual hikers who rarely run at night and don't need a performance-focused design
  • Runners on a tight budget for whom a simpler, cheaper headlamp would suffice
  • Those who prefer USB-C charging convenience over maximum output and durability
