SureFire X400U-A-RD Ultra 1000 Lumen LED Red Laser Weaponlight

The SureFire X400U-A-RD Ultra delivers professional-grade illumination and targeting capability in a single unit. This weaponlight combines a 1,000-lumen white LED with a 5mW red laser for rapid target acquisition in any lighting condition.

What Makes This Different

The X400U-A-RD integrates two critical functions without the bulk of separate components. While basic weapon lights only provide illumination, this system adds precision laser targeting that remains zeroed through thousands of rounds. The proprietary LED produces a focused beam with significant spill for situational awareness, while the red laser provides instant target reference at extended ranges.

Key Features

• 1,000-lumen white LED with 1.5 hours runtime on high setting
• 5mW red laser with adjustable windage and elevation controls
• Ambidextrous switching with momentary and constant-on modes
• Universal rail mount fits standard Picatinny and Weaver rails
• IPX7 waterproof rating withstands full submersion
• Hard-anodized aluminum construction with impact-resistant lens
• Integrated battery compartment uses two CR123A lithium batteries

Field performance centers on instant activation under stress. The ambidextrous paddle switches allow natural thumb operation from either side, while the laser provides immediate point of aim confirmation. Both functions operate independently or simultaneously, adapting to tactical requirements, competitive shooting, or hunting applications. The system maintains zero through heavy recoil and temperature extremes.
