Fenix TK17 – 3600 Lumen Rechargeable Tactical Flashlight
The TK17 is a 5.85" rechargeable tactical flashlight built around a CREE XHP50.3 HD LED that puts out 3600 lumens and reaches 1,083 ft (330 m).
The tail has dual switches for Instant Turbo and Instant Strobe, and the forward clicky switch needs a deep press for confident momentary operation. Four brightness levels and Strobe cover the rest. The stainless steel strike bezel is inlaid with three tungsten steel breaking tips, and an internal dual-spring structure keeps the light steady under hard impact.
Power comes from the included ARB-L21-6000B 21700 battery. It has its own two-way USB-C port, so it charges on its own and can also act as a power source. A battery level indicator sits on the tail cap. The body is A6061-T6 aluminum with a hard-anodized finish and a titanium-coated clip; the Khaki version is the color Fenix calls Stone.
