Fenix TK15R Flashlight Stay Prepared for Any Situation Serious brightness meets long-range performance with the Fenix TK15R tactical flashlight. Delivering up to 3200 lumens and throwing a beam just over 1600 feet, it’s built for situations where distance and clarity matter. Four brightness levels let you tailor the output to the task at hand, while Strobe mode provides additional capability for tactical or emergency use. The light runs on the included ARB-L21-5000 V2.0 rechargeable battery and recharges easily through a built-in USB Type-C port. Easy and Versatile Operation Control and durability are at the core of the TK15R’s design. A tactical tail switch enables quick momentary or constant-on activation, while the integrated toggle switch allows fast mode changes. A dedicated functional switch handles brightness selection and provides instant access to Strobe. Inside the flashlight, a dual-spring structure helps maintain stable performance even under heavy impact, and a battery level indicator built into the switch keeps you informed of remaining power before your next task.
