Product Description

The Fenix HM75R is a high-quality Industrial head torch which features a powerful 1600 lumen main beam, 1000 lumen floodlight and 120 lumen red light in a compact magnesium alloy head unit, powered by a replaceable 3400 mAh, 18650 Li-ion battery.

A power extender containing a replaceable 5000mAh, 21700 Li-ion battery is included. This clips to the rear of the headband and can be used to add considerable run time to the headlamp or top up its on board battery between sessions. A 1m extension cable adds versatility to the power extender, enabling it to be mounted to a belt or used in a pocket. The extender also functions as a 5000mAh power bank to charge your phone etc. Both the headlamp and power extender feature an inner waterproof USB-C charging socket with rubber cover.

HM75R is simple to operate, with a metal rotary switch for mode selection, and a central push button for brightness adjustment.

Please note that the above run times are a guide from the manufacturer and are generated by switching the headlamp on and letting it run without changing the brightness setting. The run times include power step downs due to headlamp heating and diminishing battery level. Changing the brightness setting can drastically affect these run times, particularly if the headlamp boosts back to a higher output.
