The SureFire M640DFT Scout Light Pro Turbo is a dual-fuel weapon light built for shooters who need serious long-range beam reach without sacrificing close-quarters situational awareness. This tactical rifle light combines a precision reflector that throws an intense, focused beam with enough spill light to keep your surroundings visible—ideal whether you're doing precision rifle work at distance or navigating tight spaces. The M640DFT runs on either an SF18650B rechargeable lithium-ion battery or two CR123A primary batteries, giving you the flexibility to choose your power source based on your mission.
Built tough for field use, the M640DFT is machined from aerospace-grade aluminum, hard-anodized to mil-spec standards, and sealed with O-rings to shed water and dust. The Low-Profile Mount (LPM) is one of the smart features here—it lets you dial in exactly where you want the light positioned on your rail relative to your other gear, whether that's a scope, optic, or accessories. The mount works with any MIL-STD-1913 or M-LOK rail system. Activation is handled by a momentary/constant-on pushbutton switch with a protective shroud to prevent accidental firing. The light meets IPX7 waterproof standards at 1 meter for 30 minutes, so it'll handle rain and splashes without issue.
Output and runtime depend on your battery choice. With the SF18650B battery, you get the full 550 lumens, 71,000 candela peak intensity, and a beam that reaches 533 meters—maximum reach for target identification at distance. Two CR123A batteries also deliver 71,000 candela. The design keeps everything compact and lightweight, so it won't add unnecessary bulk or weight to your rifle. Compatible with remote tape switches if you want to run pressure activation from your handguard or foregrip.
| Peak Intensity (with SF18650B or two CR123A) | 71,000 candela |
| Lumens Output (with SF18650B) | 550 lumens |
| Beam Distance (with SF18650B) | 533 meters |
| Runtime (with SF18650B) | 2 hours |
| Battery Options | SF18650B rechargeable or 2 × CR123A primary |

| Included | 2 × CR123A batteries, Scout Light Pro Low-Profile Mount |
The kit includes two CR123A primary batteries. The light also runs on an SF18650B rechargeable lithium-ion battery, which is sold separately. Both battery options deliver the same peak intensity of 71,000 candela. The SF18650B will give you the full 550 lumens, 533-meter beam distance, and 2 hours of runtime.
Yes, the included Low-Profile Mount works with any MIL-STD-1913 Picatinny rail or M-LOK slot. The LPM attaches securely without tools and lets you adjust the light's position relative to your rail and other accessories like scopes or foregrips.
Yes, the M640DFT is compatible with a host of remote tape switches, allowing you to run pressure activation from your handguard or foregrip if you prefer that setup.
The light meets IPX7 waterproof standards, meaning it's sealed and tested at 1 meter depth for 30 minutes. The aluminum body is hard-anodized and O-ring sealed to keep water and dust out, making it reliable in rain, splashes, and field conditions.
