SureFire X300U-B Ultra Weapon Light 1000 Lumens Black Anodized

The SureFire X300U-B Ultra delivers 1,000 lumens of white light output in a compact weapon-mounted package that transforms target identification capabilities in low-light conditions. This tactical light system provides the illumination power needed for positive threat identification while maintaining the durability standards required for professional and defensive applications.

What Makes This Different

The X300U-B Ultra generates significantly more light output than standard weapon lights, producing 1,000 lumens compared to the 300-500 lumens typical of competing models. The proprietary LED and reflector system creates a focused beam pattern that extends usable identification range while minimizing peripheral light spillage that could compromise the user's position. SureFire's construction methods result in a light that maintains consistent output through thousands of activation cycles.

Key Features

• 1,000-lumen white LED output with 1.25-hour runtime on single battery set
• Universal rail mount fits both Picatinny and Weaver rail systems
• Aerospace-grade aluminum body with Mil-Spec Type III hard anodizing
• Ambidextrous switching with momentary and constant-on activation
• IPX7 weatherproof rating for operation in adverse conditions
• Compatible with SureFire holsters and retention systems
• Tool-free battery replacement with two 123A lithium batteries

Field performance centers on reliable activation under stress and consistent light output across the battery life cycle. The switching mechanism responds to both light pressure for momentary activation and firm pressure for constant-on operation. The beam pattern provides sufficient spill light for peripheral awareness while concentrating the majority of output in a focused hotspot for target identification at extended distances.
