The Fenix TK22 TAC is a true tactical performer. Powered by an included rechargeable 21700 battery, the TK22 TAC flashlight can throw a maximum 2800 lumens an incredible distance of 1,772ft (540m)—almost 600 yards. The toggle tail switch allows you to quickly switch between Tactical Mode, which limits the light to only the Turbo brightness level and strobe for tactical situations, or Duty Mode which accesses all other lighting modes for on-duty demands. The TK22 tactical flashlight is impact resistant and has an IP68 rating making it dustproof and waterproof—ready to meet the demands of the military and law enforcement.
