The Fenix E40R is a compact EDC torch delivering a maximum output of 5000 lumens and a beam distance of 242 metres, with a peak intensity of 14641 candela. Four TN cool white LEDs drive the beam, controlled by a three-stage rotary switch with a spring-loaded Turbo position for instant maximum brightness, alongside a separate neck switch for Strobe. Powered by an included Fenix ARB-L21-5500 21700 lithium-ion battery, it offers a maximum runtime of 89.5 hours on the 30 lumen eco mode, recharging through a built-in USB-C port that reaches a full charge in as little as 1.5 hours with a compatible 5V/2.3A adapter. A battery level indicator as well as Fenix's intelligent overheat and low-voltage protection help manage output during extended use, while a pocket clip and magnetic tail cap keep it ready for hands-free carry. Rated IP68 with 1-metre impact resistance.
Features
- High Output: Delivers 5000 lumens and a beam distance of 242 metres on Turbo mode.
- Extended Runtime: Runs for up to 89.5 hours on its lowest setting, powered by an included Fenix ARB-L21-5500 21700 lithium-ion battery.
- Rotary Turbo Switch: A three-stage rotary switch selects modes, with a spring-loaded Turbo position for instant maximum brightness that returns to standard output on release.
- USB-C Fast Charging: Recharges through a built-in USB-C port, reaching a full charge in as little as 1.5 hours with a compatible 5V/2.3A adapter.

Note: According to the ANSI/PLATO FL1 standard, the above specifications are from the results produced by Fenix through its laboratory testing using one ARB-L21-5500 battery under the temperature of 21±3°C and humidity of 50% - 80%. The true performance of this product may vary according to different working environments and the actual battery used.
The Turbo mode delivers an ultra-high brightness burst for a short duration and cannot be sustained; therefore, its runtime is not listed in the specifications.
*The High output is measured in total of runtime including output at reduced levels due to temperature or protection mechanism in the design.
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.
