SureFire X300U-B Weapon Light - 1000 Lumens, 213m Beam, Tan Anodized Aluminum, Picatinny/Weaver/Glock Mount

The SureFire X300U-B weapon light is a 1000-lumen mounted light built for serious shooters who need dependable illumination on a pistol or rifle. Whether you're a defensive shooter, law enforcement professional, or tactical trainer, this compact light mounts directly to Picatinny, Weaver, and most Glock-style rails without tools or permanent modification. The X300U-B pairs serious output with a precision-focused beam that cuts through darkness and reaches targets at 213 meters—far enough to identify threats and maintain situational awareness in real-world conditions.

The engineering here is purposeful. SureFire's custom TIR lens produces a tightly focused hotspot surrounded by useful spill light, giving you both long-range reach and close-quarters peripheral vision in a single beam. The 1000-lumen LED doesn't waste energy; it's tailored for close- to medium-range engagements where most defensive encounters happen. Ambidextrous switching lets you activate momentary-on or constant-on with one finger, keeping your grip solid on the gun and your eyes on the target. No fumbling, no grip changes.

Build quality reflects SureFire's reputation. The body is aerospace-grade aluminum, hard-anodized to Mil-Spec standards for corrosion and impact resistance. It's sealed weatherproof and rated IPX7 waterproof to 1 meter for 30 minutes—tough enough for field use in rain, snow, and rough handling. At home on a duty pistol, a home-defense rifle, or a training gun, the X300U-B is the light choice when reliability matters.

Frequently Asked Questions

What rails will the SureFire X300U-B mount to?

The X300U-B attaches via T-slot thumbscrew clamp to Picatinny rails, Weaver-pattern rails, and Glock-style accessory rails found on most modern handguns and rifles.

Can I use the X300U-B on both a pistol and a rifle?

Yes. The light mounts to any Picatinny, Weaver, or Glock-pattern rail, so it works on duty pistols, tactical rifles, and training guns alike. SureFire also offers optional accessory switches for pistols and tape switches for long guns to tailor activation to your setup.

What does IPX7 waterproof mean, and will it survive regular use?

IPX7 means the light is waterproof to 1 meter for 30 minutes—suitable for rain, splash, and rough field conditions. The aerospace aluminum body is also sealed and Mil-Spec hard-anodized to resist corrosion, so it's built to last through regular duty use and training.

How far does the beam reach?

The 213-meter beam reach allows you to identify targets and threats at significant distance. The TIR lens creates a focused center hotspot with surrounding spill light, balancing long-range reach with close-quarters peripheral vision.
