The Fenix HM75R is an industrial, high quality, dual power headlamp with a maximum output of 1600 lumens and a beam distance of up to 223 meters.

The headlamp includes two power sources; an 18650 li-ion battery inside the headtorch and a separate 21700 li-ion battery in the power extender, connected by a durable 1 meter cable. Once the 18650 battery has depleted, the power extender can be turned on to recharge the battery whilst still in use. This combination of batteries provides impressive runtimes, such as up to 18 hours and 20 minutes at a 350 lumen output.

The power extender is detachable and can be used as a power bank to charge electronic devices and takes just 2.5 hours to fully charge via the USB Type-C port. When attached to the headlamp, it features a charging cable lock function to securely connect the headlamp and power extender, preventing any loose cables or connections.

The HM75R is a triple coloured headlamp operated by a rotary switch to select the mode between spotlight, floodlight and red light, and an electronic switch to cycle through the brightness levels once in the desired mode. The light has an intelligent brightness downshifting function, enabling the brightness level to drop down when it is within 60 mm of an illuminated object, to avoid overheating.

The Fenix headlamp is made out of a lightweight magnesium alloy material which can withstand a drop test of 2 meters on all 6 sides and has passed a 24 hour salt spray test.
