Fenix HM75R – Advanced Headlamp with Hybrid Power System

The Fenix HM75R is a modern headlamp equipped with four light emitters, USB-C charging, and the innovative Power Xtend System for extended external power support. It delivers an impressive maximum runtime of up to 234 hours in Low mode and 14 hours in High mode. A momentary Turbo mode boosts output to a powerful 1600 lumens when maximum illumination is required.

Designed for demanding users, the HM75R combines performance, durability and flexibility in one compact solution.

Durable and Lightweight Construction

The body is made of magnesium alloy, a material known for its high resistance to mechanical damage, corrosion and harsh weather conditions while remaining exceptionally lightweight. The primary light source is a white Luminus SST40 LED that produces up to 1600 lumens with a cool color temperature, ideal for applications requiring maximum brightness and clarity.

A smooth reflector focuses the beam to reach distances of up to 223 meters, providing concentrated and efficient illumination.

In addition to the main spotlight, the headlamp includes two neutral-white Luminus SST20 LEDs and a red OSRAM GR QSSPA1.23 LED. The red light supports night vision adaptation, making it suitable for activities where maintaining natural vision in darkness is important. The lamp angle can be easily adjusted by tilting the entire lighting module.

Hybrid Power Xtend System

The Fenix HM75R operates using a hybrid Power Xtend System. It can function independently with the 18650 battery housed in the main body or be supported by an additional high-capacity 21700 battery located in a rear module positioned on the back of the head for balanced weight distribution.

A built-in USB-C port allows charging at up to 1.5 A without removing the battery from the device. This practical feature ensures convenient recharging during extended use, especially when long operating times are required.

Simple and Intuitive Operation

Two separate buttons control the headlamp, allowing easy operation without removing it from your head. Each lighting system has its own dedicated switch, which is also used to adjust brightness levels. This layout makes switching modes quick and intuitive.

The HM75R includes reverse polarity protection to prevent incorrect battery installation. With an IP68 protection rating, it is resistant to dust, heavy rain and full water immersion up to 2 meters for 30 minutes. The headlamp is suitable for use in all weather conditions and during various physical activities.

Comfort is enhanced by an upgraded elastic headband that efficiently wicks away sweat and features reflective elements to improve visibility and safety during nighttime movement on roads or trails. A constant-current driver ensures stable brightness and extended runtime.
