The Surefire M640DFT is a 1,000 lumen Scout light in tan anodized finish, supplied with an 18650 rechargeable battery, a Z68 tailcap and an M-LOK adapter.
A thousand lumens is double the M340’s output, and the 18650 cell is what makes that possible. It is a longer battery, so the light is a longer unit, which is the trade against the compact model. On a rifle where rail space is available that is no cost at all, and the extra output and runtime are worth having.
The Turbo reflector concentrates that output into a tight beam, so reach improves alongside brightness rather than just lighting a wider area. The 18650 rechargeable is included rather than sold separately, and tan matches sand-colored furniture and gear. Explore more weapon lights.
