The SureFire X400 Ultra WeaponLight integrates stunningly powerful white-light illumination and bright red laser aiming capabilities in one compact rail-mountable package, an extremely effective combination for close- to medium-range engagements in law enforcement, military, and self-defense applications.
A high-performance LED generates 600 lumens of brilliant white light that is focused by a Total Internal Reflection (TIR) lens to produce a tight beam with 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 1.75 hours per set of batteries.
The X400 Ultra’s 5-milliwatt laser sight, located below the primary light, emits a high-visibility red (635 nM) beam. The laser's 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.
