Fenix TK21R Rechargeable Tactical LED Torch

The Fenix TK21R is the latest evolution in Fenix’s tactical torch line up, enhancing the already-popular TK20R V2.0 with greater power, advanced features, and faster charging. Now powered by a high-capacity 6000 mAh 21700 rechargeable battery, the TK21R delivers an upgraded 3600 lumen Burst Mode with an impressive beam range of up to 480 metres, making it ideal for law enforcement, military, search and rescue, and other mission-critical roles.

At its core, the TK21R uses a Luminus SFT90 LED and Fenix’s Digital Pulse Transmission system, providing reliable power delivery and responsive switching. Its intuitive dual tail switch system enables momentary-on function, easy cycling through four brightness levels, and instant access to both Burst and Strobe modes essential for tactical readiness in high-pressure environments.

The torch’s USB-C fast charging capability gets you back in action quickly. With a 9V 3A adaptor (not supplied), it charges in just 1.5 hours, or 2.5 hours using a standard 5V 3A charger. A waterproof screw-down sleeve protects the charging port and integrated battery status LED, ensuring full environmental sealing in harsh conditions.

Designed for durability and versatility, the TK21R features a rugged aluminium body, a stainless steel strike bezel with glass breaker inserts, and dual inner springs to resist impact and recoil, ideal for weapon-mounted use. The compact form factor ensures comfortable carry, while its thermal regulation and overheat protection maintain performance over time.

Fully compatible with a wide range of Fenix accessories including rail mounts, remote switches, holsters and more, the TK21R is a premium tactical torch engineered for serious performance in unforgiving environments. Whether you need reliable illumination on patrol, in pursuit, or in search operations, the TK21R is ready to lead the way.
