Fenix HM75R 1600 Lumen USB-C Headlamp with Battery Extender Pack | Long Runtime for Site Work, Rescue, Caving

Powerful illumination for every mission

The Fenix HM75R headlamp pairs high-performance optics with rugged hardware to offer dependable hands-free lighting in challenging environments. Delivering 1600 lumens, it reaches out to illuminate distant targets while keeping your immediate surroundings visible for safe navigation. The combination of spotlight, floodlight, and red light modes gives you flexible control over brightness, distance, and night-vision preservation.

Whether you’re operating on a windy site at dusk, exploring a limestone cave, or keeping a trail visible on a mountain path, the HM75R helps you see more with less effort. The weight is well-balanced for comfortable wear, reducing fatigue during long sessions.

Three beam modes for versatile visibility

Choose between a targeted beam for far-off details, a broad flood for close work, or a red light for low-visibility operations without compromising night vision.

• Spotlight provides long-range visibility for precise inspection and distant targets.
• Floodlight offers wide-area illumination for near-work tasks and navigation.
• Red light mode preserves night vision while maintaining situational awareness.

Power options and long runtimes

You can run the HM75R on its own or attach the battery extender back for extended sessions. With the extender, turbo can run up to 9 hours, while the lowest setting can last up to 243 hours.

• Runtime: up to 9 hours on turbo with extender; up to 243 hours on the lowest setting.
