Fenix HM55R Review: A Compact Running Head Torch With Serious Output

Introduction

Winter running demands gear you can forget you are wearing, and the Fenix HM55R makes a strong case as exactly that kind of head torch. It is the smaller sibling of the well-regarded HM65R, a light many runners have relied on for years. Fenix has essentially shrunk that proven formula into a lighter, more compact package while keeping the build quality and core functions that made the original so popular. The result is a 105g running head torch with a punchy 1,200-lumen turbo mode, IP68 waterproofing, and thoughtful safety features that feel genuinely useful on dark, wet trails.

Who the Fenix HM55R Is For

This is a torch built for runners first. If you log early morning miles, run through winter evenings, or race ultramarathons that stretch through the night, the HM55R is aimed squarely at you. The long 175-meter beam throw on turbo mode is especially valuable for picking out flags, way markers, and route features when navigating unfamiliar trails in darkness.

It also suits walkers, campers, and dog owners who want a compact rechargeable light with more than one personality. The low settings are gentle enough for close-up tasks, while the max outputs are strong enough to handle proper trail running.

Key Specifications and Build

At 105g including its 1,600mAh fully rechargeable lithium battery, the HM55R is remarkably light. The IP68 dust and waterproof rating means it can be submerged up to 2 meters, so relentless wet and windy weather is not a concern.

Fenix has built in some genuinely practical protections: intelligent overheat protection, a low voltage warning, and an automatic proximity downshift that protects both the light and surrounding surfaces when you get close to something. A four-step battery indicator on the side of the unit makes it easy to check your charge before heading out the door. Charging is handled through a waterproof USB-C port, taking the torch from empty to full in about 2.5 hours.

At a UK retail price of £79.95, it feels like a well-engineered product designed to last years, even accounting for eventual battery replacement.

Light Output and Burn Times

The HM55R offers two distinct lighting modes. The spotlight runs at 6,500K with a low setting of 30 lumens for roughly 47 hours of burn time and a 27-meter beam, and a turbo mode of 1,200 lumens with around 2 hours of burn time and an impressive 175-meter throw. That 1,200-lumen figure is genuinely impressive for such a compact unit, and it matters most for night ultras where a bright long throw helps with route navigation.

The flood beam runs at a slightly warmer 5,000K, which helps light penetrate fog and mist better than a standard white beam. Its low setting is just 5 lumens with a stated 140-hour burn time, while the max output of 350 lumens delivers roughly 3 hours 40 minutes of battery life with a 62-meter beam length.

In real use, the numbers hold up well. Expect around five and a half hours on the 350-lumen spotlight setting and roughly three hours on the equivalent flood setting. The turbo mode is technically the headline figure, but brightness will dip over time as the torch manages heat and battery. For most running, the 350-lumen high setting is the sweet spot: plenty of light, a decent beam, and roughly triple the battery life of turbo.

There is also a red light mode with constant and flashing options, activated with a double click of the side button. It is ideal for close-proximity situations and adds another layer of safety around traffic or other people.

Comfort and Fit

Comfort is where the smaller size really pays off. The HM55R is so light that you can almost forget you are wearing it, and the soft, wide elasticated headband sits nicely on the head with simple adjustment. Small perforations around the band help with breathability on longer efforts, and the high-visibility detailing throughout is a genuinely useful safety touch for road running or running near traffic.

The tilt adjustment on the light unit is another highlight. There are plenty of angle options, and each step clicks into place with a satisfying, well-engineered feel. It is easy to adjust on the move without being either frustratingly stiff or worryingly loose, which has tripped up other head torches. The one caveat: this model drops the excellent boa-style adjustment wheel of the HM65R, which made on-the-fly micro adjustments effortless. Runners coming from that torch will notice its absence.

Operation is a single side button. A quick press turns the torch on using the last-used setting thanks to memory technology, further presses cycle brightness, and a two-second hold switches between spotlight and flood modes. Some single-button torches feel fiddly, but this system works well in practice.

Things to Consider Before Buying

Two compromises come with the compact size. First, you cannot run the spotlight and flood light together simultaneously, which some other Fenix head torches allow and which gives you both close-range flood coverage and long throw at once. Second, the warmer tone of the flood beam is only subtly different from the whiter spotlight, so do not expect a dramatic color shift. Neither issue is a dealbreaker, but both are worth knowing before you buy.

Buying Advice

If you are buying your first serious running head torch, the HM55R is an easy recommendation: it is comfortable, bright, well built, and the burn times are solid for its size. If you already own the HM65R, the HM55R makes sense as a lighter, training-specific option or a backup for race days. If you want the ability to run both beams together or you value the boa-style strap adjustment, the larger HM65R remains the better fit.

Conclusion

The Fenix HM55R adds another genuinely capable head torch to an already strong lineup. It keeps the brand’s signature build quality and thoughtful features while shedding weight and bulk, and its real-world brightness and battery life impress for such a small unit. For winter runners and night trail racers, it is one of the most complete compact options available.
