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.
