READY GUNNER PURCHASE GUIDE
SureFire M640DF Scout Light Pro – 1500 Lumen
The SureFire M640DF Scout Light Pro is a full-size Dual Fuel rifle weapon light in black. On the included SF18650B rechargeable battery it produces 1,500 lumens; on two 123A batteries, 1,200 lumens. The Low-Profile Mount attaches to MIL-STD-1913 Picatinny and M-LOK rails.
Dual Fuel Output
With the SF18650B: 1,500 lumens, 16,000 candela, a 250 m beam, and 1.5 hours of runtime. With two 123A batteries: 1,200 lumens, 12,800 candela, a 220 m beam, and 1.25 hours. The Total Internal Reflection (TIR) lens shapes a versatile beam with reach and surround light for close- to longer-range use.
Low-Profile Mount
The Low-Profile Mount (LPM) attaches to Picatinny and M-LOK rails — both mounts are included — and lets the user optimize the light's position relative to the rail and other accessories.
Z68 Click Tailcap
The Z68 click tailcap gives momentary and constant-on pushbutton activation with a protective shroud, and the light is compatible with SureFire remote tape switches.
Construction
The body is lightweight aerospace aluminum, Mil-Spec hard anodized, with a tempered window and O-ring sealing. The light is IPX7 rated.
