Surefire Ultra LED Flashlight and Green Laser Sight from SureFire combines a 500-lumen, single-output, LED light with a 505nm Class IIIb green aiming laser for Picatinny or universal rail mounts. The light features SureFire’s 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. The selector switch, located behind the laser, switches the output modes and features a lock-out function to prohibit accidental activation during storage or when strict light discipline must be maintained. The green 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 Mil-Spec anodized aluminum housing.
