SureFire X300U-B WeaponLight

SureFire X300U-B WeaponLight – a high-output weapon-mounted light designed for installation on pistols and other firearms equipped with a compatible accessory rail. The model combines bright LED light, a long-range beam, compact dimensions, and a durable housing designed for intensive use.

The light provides 1000 lumens of output with a peak beam intensity of 11,300 candela and an illumination range of up to 213 meters. The optical system with a precision TIR lens produces an even long-range beam with a pronounced central hotspot and additional peripheral illumination. This configuration combines good range with a wide field of illumination to maintain situational awareness.

Powerful LED Illumination

The high-performance LED generates 1000 lumens of white light. The specially designed TIR optic directs it into an intense beam with a clearly defined central zone. The X300U-B is suitable for illuminating areas at close and medium distances and also helps quickly identify objects in low-light conditions.

The peripheral portion of the light output provides additional illumination around the central hotspot, contributing to better control of the surrounding area.

X300U-B Mounting

The X300U-B model is equipped with a T-slot thumbscrew clamp mounting system – a screw-locking clamp. The light installs on Universal and Picatinny accessory rails, making it compatible with a wide range of pistols equipped with corresponding rails.

To expand control options, compatibility with additional DG and XT remote switches is provided, allowing the light to be activated without changing the position of the hand.

Ambidextrous Control

The switches are located on both sides of the housing, making the light convenient to use with either the right or left hand. Two activation options are available: momentary and constant-on.

The switch design allows the light to be controlled with one finger without changing the primary grip.

Durable Housing

The SureFire X300U-B housing is made of high-strength aerospace-grade aluminum. The surface features a protective Mil-Spec Hard Anodized finish, which increases resistance to scratches, corrosion, and intensive use.

The sealed construction protects the internal components from environmental exposure. The light has an IPX7 protection rating and is designed to withstand immersion in water to a depth of up to 1 meter for 30 minutes.

Power Supply

The light uses two 123A batteries, which are included in the package. The stated runtime is up to 1.25 hours.

The compact housing, measuring only 9.55 cm in length, maintains convenient dimensions when the light is installed on a weapon.
