Why we like these:
We all know Surefire is a trusted brand name when it comes to top tier performance and reliability. The Turbo Series is no exception, delivering impressive power in a compact, rugged package, and built to perform in the most demanding conditions.
The M340DFT Turbo Scout Light is smaller and more compact than it's bigger brother the M640DFT, but it sacrifices almost nothing in performance. Still boasting 95k candela and only a slight dip in lumens, this thing packs a serious punch in a small package. Perfect for smaller setups like SBRs or PCCs.
The Turbo series may have a lower lumen output compared to some competitors or even other SureFire models, but where they truly excel is in their impressive candela rating. This higher candela translates to a tighter, more focused beam capable of reaching out much farther—making this light ideal for rifles.
Unlike lights that prioritize raw lumens for general brightness, the Turbo Series is engineered for intensity and throw, making it perfect for users who need a beam that cuts through the dark and keeps you in control at a distance.
If you're in the buy once, cry once crowd, looking for one of the best weapon lights on the market, the SureFire M640DFT should be at the top of your list.

- Dual Fuel- one 123A or one 18350 (recommended)
- Includes low profile picatinny and M-Lok mounts, although the Arisaka mounts fit as well.

See Farther. SureFire’s Scout Light Pro series rewrote the rules of WeaponLight versatility. The M340DFT-PRO Turbo Mini Scout Light Pro combines high-candela performance and dual-fuel capability. The M340DFT-PRO's Turbo Series reflector delivers the farthest-reaching beam of any SureFire long gun WeaponLight in a compact form factor. As a result, it is ideal for long-range target identification. The M340DFT-PRO projects a peak beam intensity of 95,000 candela, using the included SF18350 rechargeable lithium-ion battery, or 55,000 candela with a single 123A primary battery. Its precision reflector creates a tightly focused, concentrated shaft of light with minimal bounce when peering over, under or around barricades. Our Low-Profile Mount (LPM) delivers unprecedented versatility, allowing the user to optimize the light’s position relative to the rail and other attached firearm accessories. Rugged and reliable, the LPM easily and securely attaches to any MIL-STD-1913 or M-LOK rail. Constructed of lightweight aerospace aluminum, Mil-Spec hard anodized, and O-ring sealed to keep out the elements, the M340DFT-PRO is the best-performing, most feature-rich WeaponLight for its size.
