🔦 Fenix TK21R - Massive brightness & range - 3,600 lumens, 480 m beam

A powerful Luminus SFT90 LED delivers an impressive 3600 lumens that reach up to 480 meters – ideal for precise orientation, hazard detection, or search tasks in complete darkness.

⚙️ APF system – maximum reliability thanks to modern switching technology

The Fenix TK21R is equipped with the innovative APF system (Advanced Pulse-frequency Transmission System) – a groundbreaking technology that makes signal transmission between the switch and LED significantly more stable and interference-resistant.
Unlike conventional lamps, which rely on multiple electronic components, APF allows for a simplified and more robust circuit architecture. The result:

• faster response times with every push of a button
• constant light output without flickering, even with vibrations or recoil
• high reliability in extreme tactical situations

Especially in safety-critical applications—such as for police, military, or emergency services—APF technology ensures that your lamp always does exactly what it is supposed to do: immediately and without delay.

🎯 Quiet dual tail switch – turbo and strobe at the touch of a button

Thanks to the dual tail switch, you have lightning-fast access to:

• Direct access to turbo mode – no detours
• Direct strobe signal – can be activated quickly in an emergency
• Access to four brightness levels

An ergonomic design that offers maximum control even under stress.

🔌 USB-C charging & battery management – fast & smart

With the integrated, waterproof USB‑C port, the included 6000 mAh 21700 battery charges in just approx. 1.5 hours. The practical battery status indicator informs you of the charge status at all times – so you're never left in the dark.

🛡 IP68, shockproof & tactically robust

The A6061-T6 aluminum housing with HA III anodization is dustproof and waterproof (IP68) and can withstand drops from up to 1 m. The steel strike tip on the lamp head can be used as a glass breaker in an emergency.
