The Rail-Lock version of our popular WeaponLight is trusted by law enforcement and military operators worldwide and now boasts a powerful LED-generated output of 1,000 lumens. The TIR lens focuses the light to create a high-intensity beam with a larger center spot and surround light, making it highly effective for close- to medium-range engagements. This light helps you identify threats at significant distances while temporarily impairing your adversary&';s vision and provides extensive peripheral illumination for situational awareness. The ambidextrous switching allows for easy activation with one finger, providing momentary-on or constant-on control. Its aerospace aluminum body is Mil-Spec hard anodized for scratch and corrosion resistance and is weatherproof with an IPX7 waterproof rating to 1 meter for 30 minutes. The X300U-A is a reliable standard of excellence that you can trust.
