SureFire 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.

  • Max Output: 110 lumens (more than 5 times the light output of a two-D-cell flashlight); continues producing tactical-level light for 2.4 hours
  • Highly visible red-laser sight power output of 5mW at a wavelength of 635 nm
  • Versatile beam is perfect for close- and long-range applications
  • Ambidextrous, ergonomic tactical switching enables fail-safe operation under fire
  • Instantly attaches to most handguns with a Universal rail and handguns/long guns with a Picatinny rail
  • 1.86" high by 1.46" wide by 3.54" long; weighs 4.4 ounces with batteries
  • Batteries—two SF123A lithiums with 10-year shelf life
  • Aerospace-grade aluminum construction with Mil-Spec Type III hard-anodized finish
  • O-ring seals keep out dirt, propellant residue, and moisture
  • Accepts optional pressure-activated switches for precision control without altering grip on weapon

SureFire X400 LED WeaponLight April 9, 2012
Reviewer: Gunting from Buffalo, NY United States  
I am delighted with this product.  I had read mixed reviews online.  Some users complained that the unit was heavy or hard to zero.  On the contrary, the X400 doesn't seem much heavier than the X300 it replaced, and it zeroed in under five minutes.  The rail-attachment clamp locks very firmy into place, and the controls are intuitive.  Best of all, the laser is so bright that it's visible on white surfaces even when the 170 lumen light is running.  I had expected the laser would be washed out.   I highly recommend this product!

Great light/laser combo November 7, 2011
Reviewer: robert krake from boardman, OH United States  
I have had this unit for just under a year now. I have to say, I just love it. i've used it on my AR and on my FNP 45. It works perfect and the laser is a nice added touch. Controls are just where they need to be and work properly. The only con I have for the unit is the brightness. For the price i would expect more. I guess that's not such a big deal as the output does blind people. Great unit over all
