Increase Force. Decrease Mass. The Mini Scout Light Pro is mighty in stature yet minimal in structure. It feeds off a single 123A lithium battery, but its virtually indestructible LED devours the darkness with 500 lumens of light focused by a TIR lens into a high-intensity hybrid beam. Its ideal for close- to longer-range operations. SureFire's new Low-Profile Mount (LPM) delivers unprecedented versatility, allowing the user to optimize the lights position relative to the rail. Rugged and reliable, the LPM easily and securely attaches to any MIL-STD-1913 or M-LOK rail. Activation is easy: Simply click the Mini Scout Light Pro's push-button tailcap switch or press its pressure-activated tape switch, included on appropriate models. Machined from lightweight aerospace aluminum with a Mil-Spec hard anodized finish and O-ring sealed to keep out the elements, the ultra-compact Mini Scout Light Pro withstands the rigors of combat without weighing down your weapon.Specifications and Features:Output: 500 LumensBulb Type: LEDOAL: 4.10"Weight: 3.65 ozBattery Size: CR123AProofs: IPX7 WaterproofColor: Black AnodizedMaterial: AluminumHead Diameter: 1.125"Filter Color: WhiteSwitch Type: Push Button/Tail Cap
