Overview of the SureFire M640DFT Turbo Scout Light Pro | M640DFT-PRO
The SureFire M640DFT Turbo Scout Light Pro (model M640DFT-PRO) is a dual fuel rifle weapon light built for long-range target identification. SureFire rates it at 100,000 candela and 700 lumens on the included SF18650 rechargeable battery, with a beam that reaches 632 meters.
You see movement at the far edge of a field or the end of a long hallway, and you need to know what it is before you act. A wide flood beam fades out at distance. The Turbo reflector focuses output into a tight, far-reaching beam so you can identify what is in front of you.
Two Ways to Power It
-
SF18650 rechargeable (included): 700 lumens, 100,000 candela, 632 meters, 2.75 hours.
-
Two 123A lithium: 600 lumens, 90,000 candela, 600 meters, 1.75 hours.
Who It Is For
Patrol officers with a duty carbine, SWAT teams, and hunters who need to identify targets at distance get long reach in a 5.9 inch, 5.5 ounce light.
Key Features
-
Turbo reflector: SureFire states it delivers the farthest-reaching beam and longest runtime of any SureFire long-gun WeaponLight.
-
Dual fuel power: runs on one SF18650 rechargeable battery (included) or two 123A lithium batteries. Keep spares on hand with the SureFire SF18650B Battery or SureFire SF123A 123A Lithium Batteries.
-
Low-Profile Mount (LPM): attaches to MIL-STD-1913 (Picatinny) or M-LOK rails, with cleats for both included. You can set the light's position relative to the rail and your other accessories.
-
Switching: ZE68 tailcap gives momentary-on or constant-on pushbutton activation, with a protective shroud over the button.
-
Remote ready: SureFire states the light works with a range of SureFire remote switches.
-
Rugged build: aerospace aluminum body, Mil-Spec hard anodized, O-ring sealed, with a tempered window and a recoil-proof LED.
-
Waterproof: SureFire states it meets the IPX7 standard at 1 meter for 30 minutes.

Compatibility
-
Firearms: made for rifles, carbines, and shotguns with a MIL-STD-1913 (Picatinny) or M-LOK rail. SureFire builds it as a long-gun WeaponLight, not a handgun light.
-
Other rails: KeyMod and other rail systems need a separate adapter.
-
Batteries: use one SF18650 or two 123A lithium cells. SureFire states the SF18650 is required for the full 700 lumen output.
-
Remote switches: SureFire uses different rear caps on its dual fuel and standard Scout Light bodies. Confirm a remote switch lists the M640DFT before you order it.

Intended Users
Patrol officers and deputies mount the M640DFT on duty carbines and shotguns to identify threats across parking lots and open ground. SWAT and tactical teams use the tight Turbo beam to light distant windows and doorways. Military users choose it for its rugged, waterproof build. Hunters and rural property owners use it to identify animals and intruders at long range, and home defenders who want a rifle light with serious reach choose it too.

Available at WCUniforms
WCUniforms is owned by a U.S. Marine veteran and a U.S. Coast Guard veteran who also served as a city police officer and EMT, so we know what a long gun light has to survive on duty. Since 2013, our San Diego team has supplied officers, soldiers, and armed civilians, and this SureFire ships from our Michigan warehouse to customers across the United States. Compared with a standard flood-style rifle light, the M640DFT puts more of its output downrange where you need it.
