Fenix HM75R PRO 3500 Lumens Rechargeable Headlamp

The Fenix HM75R PRO is a high-performance rechargeable headlamp designed for demanding professional, industrial and outdoor applications. With a maximum output of 3500 lumens and a beam distance of up to 398 metres / 1,306 feet, it combines powerful long-range illumination with wide-area coverage. Four lighting modes — spotlight, floodlight, combined spotlight + floodlight, and red light — provide flexible lighting for search and rescue, industrial inspection, caving, patrol work and extreme outdoor use. The HM75R PRO features a rugged yet lightweight magnesium alloy body and an intuitive rotary switch paired with an electronic brightness button for fast access to its 16 lighting modes. A built-in proximity sensor automatically reduces brightness when the lamp is too close to an object, helping reduce heat-related risk during close-range use. Power is supplied by an included Fenix ARB-L21-5500 21700 rechargeable Li-ion battery, providing 5500mAh of capacity and up to 516 hours of runtime. The battery is replaceable, and the headlamp recharges directly through an inner-waterproofed USB-C charging port in approximately 1.5 hours with a 5V/2.5A or higher adapter.
