The Fenix TK22R Pro is a dual-mode tactical flashlight built for duty, patrol, and search work. A 3-in-1 smooth reflector with three Luminus SFT42R LEDs puts out up to 4200 lumens and reaches 440 meters, a big step up from the original TK22R's 3200 lumens, with a tight, far-reaching beam for picking out detail at distance. Fenix's patented FlexiSensa control toggle switch at the tail selects Duty mode, Lockout, or Tactical mode, and the dual tail switch puts every function under your thumb. In Duty mode you step through Eco, Low, Med, and High, with instant 4200-lumen Turbo a half-second press away. In Tactical mode the light runs Eco or Turbo, with instant Strobe on demand. Lockout keeps it from switching on in a holster or bag, and the light remembers the last output you used. It ships with a Fenix ARB-L21-5500 21700 battery for up to 35 hours of runtime, and a flip-covered USB-C port charges it in about 1.5 hours with a 9V fast-charging adapter. A battery level indicator at the tail shows the charge at a glance. The A6061-T6 aluminum body has a matte HAIII hard-anodized finish, an IP68 rating, and dual internal springs for stable light under hard impact, and the titanium-plated stainless steel strike bezel carries three tungsten steel tips for breaking glass in an emergency. At 6.50 inches and 8.85 oz with the battery, it comes with a holster for duty carry.
