The Fenix HM71R V2.0 is a multi-purpose headlamp built for industrial and other demanding working environments, delivering a maximum output of 3500 lumens and a beam distance of 275 metres, with a peak intensity of 18880 candela. Spotlight, floodlight and red auxiliary light cover a wide range of scenarios, driven by a Luminus SFT-60 LED (spot), a Luminus SST-20F LED (flood), and two HFL1-R red LEDs. Powered by an included Fenix ARB-L21-5500 21700 lithium-ion battery, it offers a maximum runtime of 337 hours on the low floodlight mode, recharging through a USB-C port in around 2 hours from empty. A toggle switch paired with an electronic switch keeps operation simple, while a magnetic tail and detachable lamp body allow flexible mounting on or off the head. Rated IP68 with 2-metre impact resistance.

Performance and Runtime Disclaimer
How to read the data: The outputs provided above are maximum outputs for each mode, and the runtimes provided are the time it takes to drop to 10% of the initial output. This is in line with the International Flashlight Testing Standard ANSI FL1.
Any visual representations (graphs) of the data are approximate only.

The actual output of the torch/headlamp is controlled by an in-built temperature regulation system. As the torch/headlamp heats up, the brightness will drop to prevent overheating. The Turbo modes of torches/headlamps usually drop down significantly after anything from 15 seconds to 2 minutes. High modes often also experience a drop down over time. Medium and Low modes, however, can be constant for very close to the length of time specified. As the torch/headlamp cools down, either from being turned off or from being used on a lower output level, you will be able to access higher brightness levels again.
Example: An output of 2000 lumens and runtime of 5 hours does not mean 2000 lumens for 5 hours — it means it starts at 2000 lumens and drops below 200 lumens after 5 hours of continuous use.
Turbo and high modes may be unavailable or limited as the battery gets low on charge.
Exact specifications can vary between torches, batteries, age and environments.
