Fenix HM55R Lightweight Multi-LED Rechargeable Headlamp – 1,200 Lumens

Fenix HM55R Lightweight Multi-LED Rechargeable Headlamp – 1,200 Lumens

The Fenix HM55R Lightweight Multi-LED Headlamp is a compact, high-performance rechargeable headlamp designed for professional fieldwork, industrial maintenance, outdoor adventures, and everyday hands-free illumination. Delivering up to 1,200 lumens with a maximum beam distance of 574 feet (175 meters), the HM55R combines powerful lighting performance with a lightweight design weighing just 3.70 ounces, including the battery and headband.

Featuring independent spotlight, floodlight, and red light sources, nine lighting modes, and an included 1600mAh rechargeable battery, this versatile headlamp adapts to a wide range of lighting requirements. USB-C charging, an adjustable head angle, and IP68-rated construction make the HM55R a dependable lighting solution for demanding work environments and outdoor activities.

1,200-Lumen High Performance LED Lighting

The Fenix HM55R incorporates three dedicated LED light sources to provide focused long-distance illumination, wide-area lighting, and red light for low-light environments. Its powerful spotlight delivers up to 1,200 lumens with a beam distance reaching 175 meters, making it ideal for nighttime navigation, field inspections, and locating distant objects.

The separate floodlight produces up to 350 lumens of broad illumination with a high color rendering index (CRI) of 90, providing improved color recognition for close-range tasks, equipment inspections, and detailed work.

Three Independent Light Sources

• Spotlight: Luminus SST25 LED with a maximum output of 1,200 lumens and a 6500K color temperature for focused long-distance illumination.
• Floodlight: Luminus SST20V-Ra90 LED with a maximum output of 350 lumens and a 5000K color temperature for broad, high-CRI close-range lighting.
• Red Light: Dedicated 2835 red LED with constant-on and flashing modes for low-light visibility and signaling.

Each LED has a rated lifespan of 50,000 hours, providing long-lasting lighting performance across a variety of professional and recreational applications.

Nine Lighting Modes for Maximum Versatility

The HM55R features four spotlight brightness levels, three floodlight brightness levels, and two red light modes. This flexible lighting system allows users to select the appropriate beam pattern and brightness for the task while managing battery consumption.

Use the spotlight for long-distance visibility, the floodlight for close-range work, or the red light to help preserve dark adaptation during nighttime activities. The flashing red mode provides an additional signaling option.

1600mAh Rechargeable Battery & USB-C Charging

The Fenix HM55R includes a user-replaceable Fenix ARB-L18-1600 rechargeable 18350 lithium-ion battery with a capacity of 1600mAh. The battery provides up to 141 hours and 10 minutes of runtime in the lowest floodlight setting, offering extended operation for multi-day outdoor activities and emergency preparedness.

The integrated USB Type-C charging port allows the battery to be recharged directly inside the headlamp. A full recharge takes approximately 2.5 hours using a compatible 5V/1A or higher charging adapter. The removable battery design also allows users to carry compatible spare batteries for extended field operations.

Lightweight Design & Adjustable Head Angle

Weighing just 105 grams with the battery and headband installed, the HM55R provides comfortable hands-free lighting without the bulk of larger headlamps. Its compact housing and adjustable headband are designed for extended wear during work, hiking, camping, and other outdoor activities.

The adjustable lamp angle allows users to direct the beam toward the work area, walking path, or nearby equipment without repositioning the entire headlamp. This feature is especially useful for maintenance tasks, equipment inspections, and hands-on fieldwork.

Large Side Switch & Convenient Operation

A single large side switch provides convenient access to the headlamp's lighting functions. Users can switch between spotlight and floodlight modes, adjust brightness, and activate red light without navigating complicated controls.

• Press and hold the switch for 0.5 seconds to activate white light.
• Double-click the switch while the headlamp is off to activate red light.
• Press and hold the switch for approximately 1.2 seconds to switch between spotlight and floodlight modes.
• Single-click the switch to cycle through brightness levels within the selected lighting mode.

Battery Level Indicator & Low-Voltage Protection

The integrated battery level indicator provides a convenient visual reference for remaining battery capacity. Check the battery level by briefly pressing the switch while the headlamp is off.

• Solid green: 80%–100% battery capacity
• Flashing green: 50%–80% battery capacity
• Solid red: 20%–50% battery capacity
• Flashing red: 1%–20% battery capacity

Low-voltage protection automatically reduces brightness as battery power decreases. When the battery reaches a low charge level, the indicator flashes red to remind users to recharge or replace the battery.

Intelligent Overheat Protection

The HM55R incorporates intelligent temperature regulation to manage heat during high-output operation. When the headlamp reaches approximately 55°C (131°F), the system automatically reduces brightness to help control operating temperature.

Once the temperature decreases below the regulation threshold, the headlamp gradually restores the selected output level when operating conditions allow.

Durable Aluminum Construction & IP68 Protection

Constructed from durable A6061-T6 aluminum, the Fenix HM55R is built for demanding outdoor and professional environments. Its IP68-rated housing provides protection against dust and water ingress, while its 2-meter impact resistance adds durability for fieldwork, maintenance, and outdoor recreation.

The internally waterproof USB-C charging port provides additional protection against moisture. The charging port cover should remain securely closed when the headlamp is not being charged.
