Surefire X400u-a Blk 1000lm W/lsr

The Surefire X400U-A Black is a compact weapon-mounted light and green laser system delivering 1000 lumens of tactical illumination with integrated aiming capability. Purpose-built for pistol and long gun platforms, this light-laser combo prioritizes operator control and target identification across variable lighting conditions—from low-light interior spaces to mid-range outdoor engagement scenarios common in law enforcement, military, and armed civilian defense applications.

The 1000-lumen output combines a recoil-proof LED with a specialized Total Internal Reflection (TIR) lens to produce a tactical beam with extended throw and controlled surround light that accommodates peripheral vision without creating glare wash. The integrated 5-milliwatt green laser sight is optimized for human photopic and scotopic response, offering superior visibility compared to red laser alternatives across daylight and darkness. This pairing—high-output white light coupled with green laser targeting—allows rapid threat assessment and positive identification while maintaining secondary aiming capability when primary sight systems are obscured or tactical situation demands non-lethal or non-destructive confirmation.

The X400U-A suits operators and defensive-armed civilians who require a single mounting solution that consolidates illumination and aiming into one compact footprint. Its profile and weight distribution make it compatible with standard tactical rail systems on AR-pattern rifles, shotguns, and rail-equipped pistols. The black anodized finish resists corrosion and provides low-light signature control. Designed for users who prioritize reliable target identification over minimalist kit philosophy, the X400U-A represents a mature balance between light output, laser utility, and mounting versatility.
