Surefire X400u-a Blk 1000lm W/lsr - SFX400U-A-RD

The SureFire X400U-A in black is a compact weapon-mounted light system combining ultra-high-output illumination with an integrated red laser sight, delivering 1000 lumens of tactical-grade brightness. This dual-function platform is engineered for patrol rifles, carbines, and tactical pistols where operators need both searchlight-class illumination and precision aiming capability from a single rail-mounted package.

The X400 Ultra's 1000-lumen white-light output is generated by a recoil-proofed LED paired with a specialized total internal reflection (TIR) lens that produces a focused tactical beam with sufficient surround light to preserve peripheral vision awareness. The integrated 5-milliwatt red laser is optimized for human eyesight sensitivity and remains visible at extended distances without excessive bloom. Together, these systems operate on a two-stage activation switch—momentary or constant-on white light, laser, or both—allowing operators to adapt quickly to changing tactical scenarios. The compact profile (4.75 × 1.75 inches) and light weight (0.5 lbs) minimize rail mounting stress on modern piston-driven or direct-impingement carbines, while the sealed construction withstands harsh field conditions including prolonged exposure to moisture and abrasive environments.

Purpose-built for law enforcement tactical teams, military point-of-aim applications, and civilian precision shooters who prioritize target identification in low-light or high-stress engagements. The combination of searchlight-class illumination—sufficient to overwhelm dark-adapted vision and temporarily disorient potential threats—paired with a laser aiming system makes this platform effective across short-range room-clearing operations to extended outdoor patrol scenarios where positive target confirmation is mission-critical.

Weapon-mounted light systems have become standard issue across tactical units due to their force-multiplier effect: the ability to identify threats, mount an accurate shot, and communicate positional advantage simultaneously. The X400 Ultra-A positions SureFire's experience in laser and illumination engineering directly at the operator's point of aim, eliminating the need to manage separate light and sight tools during dynamic operations.
