The Fenix HP35R is a USB-C rechargeable search and rescue headlamp delivering up to 4,000 lumens with versatile spotlight, floodlight, and combined beam modes. It features glove-friendly rotary and electronic switches for easy control over 12 brightness levels—four per mode—and includes a built-in red safety light for low-light visibility.
Powered by a quick-release battery case housing dual 5,000 mAh batteries, it provides runtimes up to 500 hours on low settings and doubles as a power bank for charging devices in the field. The headlamp is rated IP66 waterproof and impact-resistant to 2 meters, built to withstand demanding conditions.
