Fenix TK11 Pro Rechargeable Duty Flashlight 1650 Lumens Tactical Light

The Fenix TK11 Pro is a compact law enforcement and duty flashlight built for the moments when you need full brightness instantly, without fumbling. A Luminus SST40 LED puts out 1650 lumens and throws a beam 360 meters (about 1,180 feet), enough to light up a parking lot, a property line, or the far end of a warehouse aisle.

Every control sits in the dual tail switch, so it all works one-handed from a standard tactical grip. Tap the tactical switch for momentary light or press it fully to lock the light on. The functional switch steps through Low, Med, and High, and gives you Strobe straight from off with a single press. The TK11 Pro remembers the last brightness you used, so it comes back on exactly the way you left it.

It ships ready to work with a Fenix ARB-L18-3400U V3.0 rechargeable 18650 battery that charges directly by USB-C, and it will also run on two CR123A batteries as an emergency backup. The A6061-T6 aluminum body with a HAIII hard-anodized finish is IP68 waterproof and impact resistant to 1 meter. At 5.41 inches long and 5.61 oz with the battery, it rides comfortably on a duty belt in the included holster.
