The SureFire M640DFT Scout Light Pro Turbo Weapon Light, part number M640DFT-TN-PRO, is a full-size rifle-mounted LED weapon light in Tan. It produces 700 lumens output and 100,000 candela peak beam intensity on the included SF18650 rechargeable cell, for a usable beam of roughly 632 metres.
DFT stands for Dual Fuel Turbo. The turbo head concentrates output into a tight, high-intensity hotspot for reach, and the light runs either the SF18650 rechargeable cell (700 lumens output, 100,000 candela peak beam intensity, 2.5 hours runtime) or two CR123A lithium primaries (350 lumens output, 65,000 candela peak beam intensity, 1.5 hours runtime). The low-profile Scout Light Pro mount fits M-LOK and Picatinny rails, and the aerospace aluminium body is sealed to IPX7.
How it compares
Also available in M640DFT Scout Light Pro Turbo rifle light in Black. For a wide 1500-lumen flood instead of a tight hotspot, see the M640DF Scout Light Pro rifle light; for a smaller body with near-identical throw, the M340DFT Mini Scout Light Pro Turbo rifle light.

Ideal for
- Lamping and night fox or vermin control, where 100,000 candela gives genuine identification distance
- Farm, kennel and yard checks after dark from a rifle-mounted lamp
- Airsoft and training carbines on M-LOK or Picatinny handguards
- Low-light range practice and night shoots

Which rails does the SureFire M640DFT Scout Light Pro Turbo fit?
The SureFire M640DFT Scout Light Pro Turbo ships with a low-profile Scout Light Pro mount that fits M-LOK and Picatinny rails directly.
Which remote switch or tailcap works with the M640DFT?
SureFire lists the DS00, DS07, DS-SR07, SR07, ST07 and UE-SR07 switches for the Scout Light M300, M600 and M640 families, so all six fit this light. The DS00 tailcap switch is the tailcap alone, the DS07 remote switch adds a remote pressure pad, and the UE-SR07 tailcap and remote switch kit is the full kit.
How far does the M640DFT actually throw?
The SureFire M640DFT Scout Light Pro Turbo reaches 100,000 candela peak beam intensity on the SF18650 cell, which SureFire rates at 632 metres of beam distance; on two CR123A primaries it falls to 65,000 candela and 510 metres. Lumens describe total light output, while candela describe how tightly that light is focused, and candela is what determines throw.
How long does the M640DFT run on each power source?
The SureFire M640DFT Scout Light Pro Turbo runs for 2.5 hours on the included SF18650 rechargeable cell and 1.5 hours on two CR123A lithium primaries.
Is the M640DFT rechargeable, and what batteries does it take?
Yes — the SureFire M640DFT Scout Light Pro Turbo is Dual Fuel. It ships with a rechargeable SF18650 lithium cell and a charging cable, and will also run on two CR123A lithium primaries at reduced output.
M640DFT or M340DFT — which should I choose?
The full-size SureFire M640DFT Scout Light Pro Turbo gives more output, higher candela and longer runtime; the M340DFT Mini Scout Light Pro Turbo is shorter and lighter for a slimmer carbine, at 650 lumens output and 95,000 candela peak beam intensity.
