The Fenix TK21R is a 3,600-lumen duty flashlight with a 480-meter beam, built for fast access under pressure. Dual tail switches give instant burst-mode and tactical strobe, and an ARB-L21-6000 rechargeable cell handles long shifts with USB-C top-up. The HAIII A6061-T6 body and IP68 sealing keep it running through rain, drops, and rough handling — a straightforward, no-frills duty light.
