The SureFire X400U-A-RD Ultra WeaponLight integrates powerful, high intensity 500 lumen white light illumination and high visibility laser aiming capabilities in one compact rail mountable package, an extremely effective combination for close to longer range engagements in law enforcement, military, and self-defense applications.

A high performance LED generates 500 lumens of brilliant white light that is focused by a Total Internal Reflection (TIR) lens to produce a beam with a bright central area, providing greatly extended reach and significant surround light for peripheral vision. The X400 Ultra produces tactical level light—enough to overwhelm an aggressor's dark adapted vision—for 1.5 hours per set of batteries.

The X400 Ultra's laser is located below the primary light, and its aiming adjustment mechanism uses Nylok screws that won't back out from the effects of recoil, which means it rarely needs to be re-zeroed. The X400U-A-RD Ultra features our original high visibility 5-milliwatt / 635 nm red laser.

The versatile X400 Ultra can be attached to a pistol or a long gun since its Rail-Lock system permits rapid attachment/detachment to either universal or Picatinny rails. Its integral ambidextrous push/toggle switch provides one finger operation for either momentary or constant-on operation. Optional DG grip switches are available for use with a pistol, and an XT07 tape switch permits the X400 Ultra to be activated when attached to a long gun without altering your grip on your weapon.

The high strength aerospace aluminum body is Mil-Spec hard anodized for superior toughness and corrosion resistance and is O-ring and gasket sealed to keep out dust and moisture.
