The Dual Fuel Scout Light Pro brings ultimate versatility to tactical lighting. It starts with a virtually indestructible LED that blasts through the darkness with 500 lumens of light. A TIR lens produces a high-intensity, hybrid beam that's ideal for close- to longer-range operations. Then you have SureFire's new Low-Profile Mount (LPM) which delivers unprecedented adaptability, allowing you to place the Light where it works for you. Rugged and reliable, the LPM easily and securely attaches to any MIL-STD-1913 or M-LOK rail. Lastly, you can choose your power source. The dual-fuel design means you can choose the battery you want, either the included micro USB-rechargeable SF18650B for max output, or (2) 123A lithium ion batteries, which are more commonly found in stores. Never be without light again.
