You get 3,100 lumens and 36,100 candela from a single 21700 battery in the Fenix TK16 V2.0 — a hard, focused beam packed into a genuinely compact tactical flashlight. It's the light you reach for when distance matters, or when you just need a bright spot on command and no excuses. The dual tail switch keeps operation simple: click for steady light, press for instant strobe, and a pulse-frequency transmission system helps cut interference so the response stays clean when it counts. USB-C charging means less fuss at the desk or in the truck, and the compact body carries easily on a belt, a bag, or a duty rig. Whether it's patrol, search, or backup use, the TK16 V2.0 makes a genuine patrol flashlight — real power without the bulk, ready the moment you need it.
