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.
