Key Features
  • 1000 Lumen White LED
  • 635nm Class IIIb Red Laser
  • 1.125" Bezel Diameter
  • Total Internal Reflector (TIR) Lens
Combining bright light for after-dark tactical activity and a laser beam for certainty in target acquisition, the X400-A-RD Ultra LED Weapon Light with Red Aiming Laser from SureFire combines a 1000-lumen, single-output LED light with a 635nm Class IIIb red aiming laser that can be mounted on Picatinny/Weaver rails. The light features a Total Internal Reflection (TIR) lens that produces a pre-focused beam with a tight center cone of bright light, and a dimmer ring on the periphery to help maintain situational awareness. An ambidextrous toggle switch controls the momentary and constant-on modes, and is easily accessible with your support hand while keeping a firm grip on your weapon. The selector switch, located behind the laser, controls the output modes and features a lock-out function to prevent accidental activation during storage or when strict light discipline must be maintained. The red laser is easy to see and can be readily differentiated from other aiming lasers used by devices like Tasers. Designed for durability, this system features a weatherproof O-ring and gasket-sealed milspec anodized aluminum housing.
