The Fenix TK15R is a high-performance torch delivering a maximum output of up to 3200 lumens, specifically engineered for police, security, and professional use. It incorporates the advanced Iris-X dimming technology, which intelligently adjusts brightness for both short- and long-distance illumination.

The torch features two operational modes: Duty Mode and Iris-X Mode. In Duty Mode, users can select from four brightness levels ranging from 30 to 3200 lumens, along with a strobe function, and a maximum beam distance of up to 490 metres.

In Iris-X Mode, the TK15R offers fully automatic brightness adjustment, ranging from 30 to 2000 lumens. This intelligent system adapts output based on ambient lighting conditions and target distance, ensuring optimal visibility without manual input. At close range, the output automatically reduces to 30 lumens—ideal for reading documents and preserving night vision—and then increases proportionally as distance increases. A selectable 150-lumen low setting is also available for steady close-range illumination.

Powered by a high-capacity 21700 rechargeable battery, the TK15R provides reliable performance throughout extended use. At 350 lumens, it delivers continuous operation throughout the night, with digitally regulated output to ensure consistent brightness. The torch is conveniently rechargeable via a USB-C port.
