Product Overview

The Fenix TK21R is a rechargeable tactical flashlight built for high-demand situations where speed, power, and control matter. With a max output of 3600 lumens and a 1574ft (480m) beam distance, it delivers strong performance for law enforcement, security professionals, and first responders. The larger of its dual tactical tail switches offers immediate access to the Instant Burst mode, giving users maximum brightness without cycling through other levels. The soft-press, forward clicky switch ensures more control when using momentary on, even under pressure. Powered by a high-capacity 6000mAh battery, this flashlight is USB-C rechargeable via its hidden port—which enhances its IP68 dust and waterproof rating. With glass breaking tips on the strike bezel, rugged aluminum alloy construction, and a matte black, non-reflective finish, the TK21R is engineered for those that demand more from their flashlight.
