The Surefire Scout 640DF solves the battery flexibility problem for weapon light users who want both rechargeable convenience and the reliability of primary batteries as backup. It works exceptionally well for law enforcement, home defense, and tactical applications where you need powerful illumination with the option to recharge via standard micro USB or swap to disposable 123A batteries in the field. The TIR lens produces a hybrid beam with enough throw to identify targets at 250 meters while providing sufficient ambient spill for close-range awareness. What sets the 640DF apart is the dual fuel capability combined with USB rechargeable convenience—no dedicated charger required, just plug the included cable directly into the SF18650B battery, and you always have the option to run two 123A batteries when needed.
