Description

The Fenix HP35R Search and Rescue Headlamp is a professional-grade lighting system built for environments where reliability and output are non-negotiable. Delivering up to 4,000 lumens with selectable spotlight, floodlight, or combined beams, it provides long-range visibility, close-in task lighting, or both at once.

A quick-release remote battery pack keeps weight off the head while delivering long runtimes and doubles as a power bank for charging devices in the field.

FAQ

Can the headlamp run while charging another device?
Yes. The HP35R can operate while the battery case is discharging power to another device.

What causes automatic brightness step-down?
Thermal protection and low-voltage safeguards reduce output to protect the light and batteries.

Are the batteries replaceable?
No. The HP35R uses a sealed dual-battery pack designed specifically for this system.
