SureFire flashlights are known around the world as the lighting system for any and every tactical scenario. In 1969 their original product line consisted of laser sighting systems for firearms. After many years of intense research and development, the SureFire WeaponLight was born and low light law enforcement & military operations changed forever. SureFire then went on to establish themselves as the leading manufacturer of rugged, powerful and compact illumination tools for tactical applications; from weapon-mounted lights and laser sights, shield lights, baton lights & hand-held lights powerful and bright enough to qualify as force-multiplier tools that could temporarily blind, unbalance, and disorient a threat.

The X400 WeaponLight is an advanced light that slides right onto most handgun accessory rails. Its bright 170 lumen beam is focused into a tight pattern that projects much further than most comparably sized lights.

You can rely on your X400 to perform flawlessly, regardless of the climate or environment. Its housing is crafted from aerospace-grade aluminum with a Mil-Spec hard anodized finish, and o-ring seals ensure water and dust proof performance. The electronically regulated LED is virtually indestructible, and designed to endure the rigors of harsh battlefield conditions.

The X400 improves upon the performance of the X300 WeaponLight with the addition of a fully integrated visible red laser aiming module. This visible red laser can be used for target acquisition in high-stress situations, or as a less-than-lethal threat deterrent.

The SureFire Difference
SureFire strives to design and manufacture lights of ever-increasing brightness and quality while setting new standards for maximum power with minimal size. Three things characterize every product: compact size, extreme ruggedness, and a flawless high-output beam. Every SureFire illumination tool is guaranteed to produce a perfect center spot of intense light surrounded by a smooth corona of softer light.
