The Fenix TK11 Pro is a compact tactical torch delivering a maximum output of 1650 lumens and a beam distance of 360 metres, with a peak intensity of 32700 candela on high mode. It features a Luminus SST40 LED alongside Fenix's Advanced Pulse-Frequency Transmission (APF) system, which allows for a more compact structure and enhanced tactical performance. Powered by an included Fenix ARB-L18-3400U V3.0 USB-C rechargeable 18650 lithium-ion battery, it offers a maximum runtime of more than 86 hours on the lowest setting, a 3x improvement over the TK11R. A dual tactical tail switch allows instant one-handed activation and quick access to strobe mode. Rated IP68 with 1-metre impact resistance.

Note: The above specifications are the test results produced by Fenix through its laboratory testing using the Fenix ARB-L18-3400U V3.0 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 High output is measured in total of runtime including output at reduced levels due to the built-in temperature protection mechanism.
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.
