SureFire’s X400 LED Tactical Weapon Light is arguably one of the most powerful and well-constructed lights on the market. SureFire has mounted and integrated red-laser sight just below the LED bulb. This makes for added versatility from the weapon light and a very effective laser that can be employed in both close-range and long-range situations. All in all the X400 is ideal for individuals in positions like law enforcement, military, and even civilians who might need it for self-defense.
LED bulbs are perfect for applications in Tactical Weapon Lights like the X400 because they have no filament, like standard bulbs that tend to break or burn out just when you need them most. The X400 puts out an outstanding 110 lumens of white light—strong enough to temporarily blind and disarm any assailant. Another added bonus of using a LED light source instead of incandescent is that they only require about 1/10th of the energy of an incandescent bulb, producing a runtime of 2.4 hours on only one set of batteries. Not to mention the added reliability.
The X400′s bezel window is made from tempered Pyrex that is not only heat resistant and strong enough to withstand sudden temperature changes due to rain or other cold landing on the glass but it is also scratch-resistant, which helps maintain an accurately focused and maximum quality beam. Additional anti-reflective coating maximizes the X400’s light transmission.
Additional features that add to the quality and durability of the SureFire X400 are the hard-anodized aerospace-grade aluminum body and O-rings and gaskets to make this light water resistant up to 66 feet.
In keeping with it’s standard of creating versatile lights that can be used by just about anyone, SureFire has built the X400 with its patented rail-lock system, which allows it to attach to both Universal and Picatinny rails and included adapter plates for both.
This tactical weaponlight features a rotary mode selector with five positions mounted at the back end of the laser housing. This allows the X400’s user to choose between the following modes of disable, white light only, laser and white light, laser only, and disable as the tactical situation requires. SureFire has made the switching option easy to locate and change in any high pressure situation, because the last thing you want to do is fumble around with a loaded gun in a loaded situation.
SureFire X400 is most compatible for applications on compact assault rifles, PDWs, SMGs and pistol-caliber carbines. The integrated laser and white-light system eliminates the “module stack up” that often occurs where a separate laser sight and illuminator are used, adding unnecessary weight and bulk which could affect firing accuracy.
