The Fenix TK15R introduces IRIS X adaptive light control — a built-in sensor that automatically adjusts output based on your environment. Approaching a wall or reflective surface? The TK15R dials back intensity to prevent blinding glare. Step into open space and it ramps up to its full 3200-lumen potential with a 490-meter throw. This intelligent automation means you spend less time cycling modes and more time focused on the task at hand.
Powered by a single 21700 cell, the TK15R is built for tactical professionals and demanding outdoor users who need a light that thinks ahead. IP68 waterproofing, a hardened aluminum chassis, and Fenix's proven reliability round out a package that is scheduled for a spring 2026 release. The combination of sensor-driven automation and manual override makes the TK15R one of the most forward-thinking tactical lights in the Fenix lineup.
