The upgraded version of the Surefire X300U-A 1K Lumens Ultra Led Weapon Light now produces an impressive 1,000 lumens of LED light. Its TIR lens focuses this high-intensity beam, creating a larger center spot for identifying threats at long distances and disorienting adversaries. The intense beam also offers wide peripheral illumination for situational awareness. The X300 Ultra can be activated using ambidextrous switches located at the back, allowing for one-finger control. Momentary-on activation can be done by pressing either side of the switch, while constant-on activation can be done by flipping up or down. Optional DG grip switches and pressure-activated XT07 tape switches can be used to activate the X300 Ultra without changing your grip on your weapon.
