SureFire M300V 3v Vampire Scout Light w M75 Mount Tan The ultra-compact M300V Scout Light, powered by one 123A lithium battery, produces 250 lumens of brilliant white light or 100 mill watts of invisible infrared output for use with night vision devices - with no need for IR filters or spare lamps. To switch from white to infrared output, simply twist the self-locking selector ring on the dual-spectrum V-series head. In either mode, the M300V's TIR lens produces a tight beam suited for close- to medium-range applications. The high-efficiency LEDs are virtually immune to failure since there's no filament to burn out or break. The M300V comes with a momentary/constant-on pushbutton tailcap switch. The M300V clamps solidly to any long gun equipped with a Picatinny rail via its integral thumbscrew rail clamp. Constructed of high-strength aerospace aluminum with Mil-Spec hard anodizing for superior toughness and corrosion resistance, and optically coated tempered glass for durability and maximum light transmission, the M300V is O-ring sealed to keep out dust, dirt, and moisture. A battle-proven design, built to withstand the rigors of combat.
