About SureFire X400U-A

The SureFire Ultra LED WeaponLight with Green Laser is a robust and versatile tool designed for both handguns and long guns. This high-powered weapon light integrates a brilliant 500-lumen white-light illumination and a bright green laser aiming capability into a compact, rail-mountable package. It's an exceptionally effective solution for close- to medium-range engagements, making it ideal for law enforcement, military, and self-defense applications.

The high-performance LED generates a dazzling white light, focused by a Total Internal Reflection (TIR) lens. This design produces a concentrated beam with extended reach, along with significant surround light for enhanced peripheral vision. The Ultra WeaponLight delivers tactical-level light sufficient to overwhelm an aggressor's dark-adapted vision for up to 1.5 hours per battery set.

The 5-milliwatt laser sight, located below the primary light, emits a high-visibility green (505 nM) beam. This green laser is easier to see in low light conditions compared to a red laser, providing a distinct advantage. The laser's aiming adjustment mechanism uses recoil-resistant Nylok screws, ensuring it rarely needs re-zeroing.

Activation of the Ultra WeaponLight is conveniently achieved via ambidextrous switching located at the rear of the body, offering one-finger control. The switch allows for momentary-on activation, constant-on activation, and a separate switch at the rear enables you to control the white light illumination and laser sight independently or simultaneously.

Optional DG grip switches for pistols and a pressure-activated XT07 tape switch for long guns allow for activation without altering your grip on your weapon. The Ultra WeaponLight's Rail-Lock system permits rapid attachment/detachment from either Universal or Picatinny rails, adding to its versatility.

Constructed from high-strength aerospace aluminum, this durable weapon light is Mil-Spec hard anodized for superior toughness and corrosion resistance. It's also O-ring and gasket sealed to keep out dust and moisture, ensuring reliable performance in a variety of conditions.
