The Fenix HM75R Pro puts four lighting modes on your head — a focused spotlight, a wide floodlight, both combined, and a low-glare red light — so you can switch between long-range visibility and close-up work without swapping gear. Its spotlight reaches up to 398 meters at 3300 lumens, while Spot-and-Floodlight mode delivers the headlamp's full 3500-lumen output for maximum coverage, and each mode offers four brightness levels selected with a quick rotary switch and electronic button combo.

An intelligent proximity sensor automatically dims the light to Low output when something gets close to the lens, preventing overheating and glare during hands-on tasks, while built-in overheat and low-voltage protection step brightness down smoothly instead of cutting out. The included ARB-L21-5500 battery is user-replaceable and recharges in about 1.5 hours over a waterproof USB Type-C port — even while you keep working, Turbo excluded. Housed in a lightweight magnesium alloy body with IP68 waterproofing and 2-meter impact resistance, the HM75R Pro is built for search and rescue, industrial inspection, and deep backcountry work alike.
