Fenix TK11R – 1600 Lumen Tactical Flashlight
The TK11 name goes back to one of Fenix's early tactical lights, and the TK11R brings it back as a compact, rechargeable 18650 tactical light. A Luminus SFT40 LED puts out 1600 lumens in a tight beam that reaches 1,378 ft (420 m), which is a lot of throw from a light under six inches long.
Control is all at the tail. Dual tail switches put on/off and instant strobe under your thumb, so you don't cycle through modes to get to strobe. Three brightness levels and memory cover everyday use.
It comes with an ARB-L18-3400 18650 battery that charges in the light through a sealed USB-C port, and it also runs on two CR123A batteries. A holster and lanyard are included. The A6061-T6 aluminum body is IP68 rated.
