The Fenix TK20R UE flashlight features the new FlexiSensa tactical switch which allows you to switch between Tactical mode, for instant access to Turbo or Strobe only, Duty mode to single tap for all brightness levels, and Lock Out to avoid accidental activation. Intelligent memory also remembers the last level chosen, including between modes. A maximum of 2800 lumens can be thrown 1526 feet (465 meters). Quickly recharge the flashlight by unscrewing the port cover and plugging in the included USB Type-C cable.
