SureFire X300U-B Ultra LED Handgun Light 1000 Lumens

The Standard in Weapon Lights

Trusted by law enforcement and military operators worldwide, the SureFire X300U-B represents the pinnacle of handgun-mounted illumination. This best-selling weapon light delivers an impressive 1,000 lumens of LED-generated output, providing the brightness and reach you need when it matters most.

Optical Design and Performance

A precision TIR (Total Internal Reflection) lens focuses the light into a far-reaching, high-intensity beam with a larger center spot surrounded by useful spill light. This design excels at close- to medium-range engagements, allowing you to:

• Positively identify threats at significant distances
• Temporarily impair adversary vision while maintaining your own situational awareness
• Maintain peripheral illumination for comprehensive threat assessment

Ergonomics and Control

Ambidextrous switching gives you one-finger control of momentary-on or constant-on activation, regardless of your shooting hand. The light activates instantly without requiring you to alter your grip on the weapon.

Durability and Reliability

The X300U-B is built to last. Its rugged aerospace-grade aluminum body is Mil-Spec hard anodized for scratch and corrosion resistance. The light is fully sealed and weatherproof, with an IPX7 waterproof rating to 1 meter for 30 minutes—ensuring reliable performance in demanding conditions.

Mounting and Compatibility

A T-slot thumbscrew clamp attaches securely to both Universal and Picatinny accessory rails found on most modern handguns. Optional pressure-activated remote switches (DG and XT models) are available for precision control without altering your grip.

What You Get

The X300U-B stands as a standard of excellence you can trust—proven in the field and backed by SureFire's reputation for quality.
