SFX400: X400™ LED WeaponLight

The SureFire X400 is a powerful LED WeaponLight with an integrated red-laser sight mounted below its solid-state LED. Its versatile beam and highly visible laser are effective in close and long-range applications, making the X400 an ideal choice for law enforcement, military, and self-defense applications.

The X400's recoil-proof LED has no filament to burn out or break and it generates 110 lumens of blinding white light—and continues producing tactical-level light for 2.4 hours on a set of batteries. A Total Internal Reflection (TIR) lens gathers virtually all of the LED's light and projects it forward creating a tight beam that reaches deep into the darkness but has enough surround beam to accommodate peripheral vision. The red-light laser features an output of 5 milliwatts at a wavelength of 635 nanometers, making it nearly twice as bright—and much more visible—than the nearest competitor. And because the laser sight's adjustment uses Nylok® screws, which won't back out from the effects of recoil, the X400 rarely needs to be re-zeroed.

The X400 features a hard-anodized aerospace-grade aluminum body and a Pyrex® window that protects the X400's electronics while O-rings and gaskets make it water resistant. And the X400 attaches to both Universal and Picatinny rails via its proprietary Rail-Lock™ system, and comes with adapter plates for both. An ambidextrous toggle/push switch provides ergonomic, fail-safe operation, and optional SureFire grip switches allow precision control without altering one's grip on the weapon. Some firearms may require an adapter mount.
