Surefire M640DF Scout Light Pro dual fuel at 1500 lumens runs on CR123 or rechargeable cells. The dual fuel flexibility is great for varied deployments. T-slot mount keeps it stable. 1500 lumens lights up a 100 yard target easily.
Surefire M640DF Scout Light Pro at 1500 lumens has solid battery life on rechargeable 18650 cells. Dual fuel means CR123A backup is always an option. Mount holds zero through firing. Bright enough for any application I throw at it.
