Meet Your Mission Requirements. Select white-light mode and the X400V’s recoil-proof LED delivers 350 lumens of visible light shaped into a focused beam with significant reach and substantial peripheral illumination for situational awareness. Twist the self-locking bezel selector on the X400V’s V-Series head, and you’re in IR mode, delivering 120 mW of illumination that’s invisible to the naked eye but perfect for NVG. The X400V’s crisp, commercially available 0.7 mW infrared laser is suitable for force-on-force training and ideal for use with night vision devices during stealth operations. Whatever your mission calls for, the X400V can handle it.
