The Fenix TK22 TAC modernizes the classic TK22 with APF Technology and features a rotating tail switch to toggle between duty and tactical modes, providing maximum versatility. Duty Mode allows for 4 brightness levels and strobe, while Tactical Mode limits access to only turbo and strobe. For further security, the switch contains a mechanical lock, enabling you to lock the light at any brightness level, strobe, or off. With 2800 lumens from the Luminus SFT70 LED and a maximum runtime of up to almost 50 hours in Eco Mode, the TK22 TAC provides reliable performance in even demanding situations. This flashlight is also IP68-rated waterproof and resilient against drops up to 1.5 meters.
