The Fenix TK25UV is a powerful LED flashlight with a maximum output of 1000 lumens of white light and 3000 mW of ultraviolet light. It features an innovative mode-switching structure that allows you to toggle between the white LED light and the UV light. To switch modes, simply rotate the head of the TK25UV flashlight in either direction. Another feature of the TK25UV is the dual tactical switch, which allows for effortless on and off operation. Momentary activation is achieved by tapping the power switch. With the function switch located directly beneath the power switch, you can adjust the output to 15 lumens, 100 lumens, 300 lumens, and 1000 lumens. Like most Fenix flashlights, the TK25UV is IP68 certified and can be submerged in water up to two meters for 30 minutes. Additional standard features include an easy-to-carry pocket clip and an ultra-clear glass lens with an anti-reflective coating.
