The Fenix GL22 is a multifaceted tactical light designed for rail-equipped hardware. With a ARB-L16-700UP Li-ion battery, it provides up to 17 hours of runtime. It can also use CR123A batteries. Navigating the white light and red laser is easy, thanks to the ambidextrous switches with a momentary-on feature. The powerful Luminus SST20 LED produces 750 lumens, and it fits many Glock and MIL-STD-1913 Picatinny rail systems, like the Glock 36 with standard rail and Springfield XDs. This must-have tactical light from Fenix is perfect for any enthusiast.
