Designed to offer versatility and durability to tactical professionals, SureFire's black M623V Vampire IR/White LED Scout Light Weapon Light is outfitted with a 350-lumen output white LED and a 120mW, 860nm invisible infrared (IR) LED. This dual output capability allows its use in conventional and stealth operations, with switching from IR to visible light accomplished with a twist of its self-locking selector on the bezel. A factory-focused Total Internal Reflection (TIR) lens optimizes the visible light's throw and produces a beam with a bright center, and a dimmer peripheral ring without holes or hotspots. Its regulated output is designed to maximize battery life and provide consistent beam intensity throughout the life of the battery.
