Description

3600 Tactical Flashlight

The Fenix TK21R is a tactical flashlight built to keep you prepared for any situation. With dual rear tactical switches, it provides quick and silent access to its full range of modes. Delivering a powerful 3,600 lumens and a beam throw of up to 480 yards, the TK21R is ideal for law enforcement, patrol duty, and search and rescue operations. Choose from three brightness levels or two specialized modes: Burst, for immediate maximum output in emergencies, or Strobe, designed to disorient threats. The intuitive dual-tail switch design ensures silent, precise control so you're always ready to respond.

USB-C Fast Charging

Powered by a high-capacity 6000mAh battery, the TK21R delivers up to 72.5 hours of runtime on its lowest setting. A real-time power indicator keeps you informed of battery status, while the hidden USB-C port enables fast charging in just 1.5 hours.

Built Tough

Weighing only 7.81 ounces, the TK21R is lightweight enough for extended use without sacrificing strength. With an IP68 waterproof rating and 1-meter impact resistance, it’s built to perform reliably in tough conditions—from rugged terrain to heavy rain.
