The SureFire X400 Ultra WeaponLight integrates stunningly
powerful white-light illumination and bright green laser aiming capabilities in
one compact rail-mountable package, an extremely effective combination for
close- to medium-range engagements in law enforcement, military, and
A high-performance LED generates 500 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 1.5 hours per set of batteries.
The X400 Ultra’s 5-milliwatt laser sight, located below the primary light,
emits a high-visibility green (505 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.
Activating the X400 Ultra is done via ambidextrous switching located at the
rear of body, providing one-finger control — press the switch on either side
for momentary-on activation, flip up or down for constant-on activation. A
separate switch at the rear of the X400 Ultra allows you to (1) activate white
light illumination only, (2) activate white light illumination simultaneously
with the laser sight, (3) activate the laser sight only, or (4) disable the
entire X400 Ultra. See illustration at upper left.
Optional DG grip switches (for pistols) and a pressure
activated XT07 tape switch (for long guns) permit the X400
Ultra to be activated without altering your grip on your weapon.
The versatile X400 Ultra can be attached to a pistol or a long gun since its
Rail-Lock® system permits rapid attachment/detachment from either
Universal or Picatinny rails. Its 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.
