Fenix TK16 v2.0 Tactical Flashlight - 3100 Lumen Long Throw

In this review the Fenix TK16 v2.0 is evaluated as a purpose-built tactical flashlight for users who need a true long-throw duty light. The bottom line: it is best for patrol, search and rescue, and outdoor work because of its combination of a 3100 lumen max output, a reflector and tungsten inlay bezel that reach beyond 415 yards, and a preinstalled high-capacity USB-C rechargeable battery that supports extended runtimes. The reviewer found it solidly built, weatherproof, and designed for fast one-hand operation while carrying or wearing tactical gear.

Key Features

• High output: The 3100 lumen maximum provides powerful illumination for long-range identification and search work.
• Long throw: The reflector and tungsten inlay bezel combine to produce a beam that exceeds 415 yards for focused distance lighting.
• Extended runtime: The included USB-C rechargeable ARB-L21-5000U cell delivers hours of use and charges with the supplied cable.
• One-hand operation: Tactical tail switch plus a secondary selector allow momentary-on, constant-on, five brightness levels and instant strobe with quick access.
• All-weather durability: All metal construction with IP68 waterproofing and impact resistance tolerates harsh conditions and wide temperatures.
• Complete kit: The package includes holster, lanyard and a LumenTac Organizer for transport and accessory management.

Who It's For

The TK16 v2.0 suits first responders, night search teams, security officers, and serious outdoorsmen who prioritize a long-throw tactical beam and rugged construction. Its one-hand tailcap controls and instant strobe make it practical for duty use and quick transitions between modes.

Hobbyists who want a lightweight EDC for casual home use will find this light bulkier than compact pocket lights, and those who need the absolute maximum thermal comfort on long Turbo runs should be aware that high output generates noticeable heat under sustained Turbo use.

Pros & Cons
