Fenix HM75R Headlamp


The HM75R headlamp is tailored for adventurers and professionals alike. Crafted from magnesium, this headlamp is 30% lighter than its aluminum counterparts. It comes equipped with dual power sources: a primary battery for the headlamp and an extendable powerbank that can be detached and used on the go, complete with a convenient belt clip. The HM75R features a versatile lighting system with a spotlight and floodlight white output, alongside a red light output for night vision preservation. Navigation through these modes is quick and easy with a rotary selection switch, and adjusting brightness levels is a breeze with a simple button press.

Boasting 1600 lumens of maximum output and reaching distances up to 732 feet and up to 18.9 hours of maximum runtime, the HM75R will be there to meet your needs. Charging is swift and efficient with USB-C fast charging, fully charging the headlamp in just 4 hours and the extender in 2.5 hours, while the extender also supports 18W fast discharge for your devices. It also features an intelligent brightness downshift technology that automatically adjusts the light intensity to prevent blinding when approaching objects closely. 

Designed to withstand the toughest conditions, the HM75R’s full metal body is both impact and corrosion-resistant. The extender cable securely locks into the headlamp, ensuring a reliable connection. Rated IP68 for waterproofing and tested for 2-meter drops, this headlamp is ready for any challenge. Additionally, the flashing red output enhances visibility and safety. The package includes 2 batteries - the ARB-L18-3400 battery goes into the headlamp and the ARB-L21-5000v2 battery goes into the included power bank. Whether for professional use, outdoor adventures, or emergencies, the HM75R headlamp is your dependable companion, lighting the way forward.
