Function
The SureFire X400 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.
