Master the Darkness: The SureFire M340DFT-PRO Turbo Mini Scout Light Pro – Unrivaled Tactical Illumination

For those who operate where light is a luxury and precision is paramount, the SureFire M340DFT-PRO Turbo Mini Scout Light Pro stands as a beacon of advanced tactical illumination. This compact, yet extraordinarily powerful, weapon-mounted light is engineered for peak performance in the most demanding environments, ensuring that whether you're engaging targets at extended ranges or navigating complex close-quarter scenarios, you possess the decisive advantage of superior vision.

Designed to transcend the limitations of traditional weapon lights, the M340DFT-PRO offers a unique blend of high-candela output, dual-fuel flexibility, and an innovative mounting system that redefines versatility. It’s more than just a light; it’s an essential piece of equipment for anyone serious about low-light operations, offering a clear solution to the challenge of positive target identification and enhanced situational awareness in obscured conditions.

Unmatched Illumination Performance: See Further, Identify Clearly

What makes the SureFire M340DFT-PRO a standout choice for professionals and serious enthusiasts? It’s primarily its groundbreaking illumination capabilities, specifically engineered for long-range engagement. The heart of this performance lies in its sophisticated TIR (Total Internal Reflection) lens and LED emitter, which together create a highly focused, intense beam of white light.

  • Superior Candela Output: This is where the M340DFT-PRO truly shines. With an impressive peak beam intensity of 95,000 candela when powered by the included SF18350 rechargeable lithium-ion battery, or a robust 55,000 candela with a single 123A primary battery, this WeaponLight projects a tightly concentrated shaft of light. Candela, often misunderstood, is the measure of light intensity in a specific direction – directly correlating to how far and how clearly you can identify a distant target. This high candela output allows for unparalleled target recognition at significant distances, making it ideal for precision rifle platforms and applications requiring extended vision.
  • Optimal Lumens for Clarity: While candela focuses the beam, the light also delivers a powerful output of 350 / 650 lumens. This balance ensures that while the beam reaches far, there’s also sufficient wide-angle spill light. This spill illumination is crucial for maintaining situational awareness, allowing the user to scan their immediate surroundings for threats or obstacles without losing the primary focus on the target. This blend of focused intensity and ambient illumination is vital for fluid movement and decision-making in dynamic tactical situations.
  • Farthest-Reaching Beam in a Compact Form: Despite its impressive throw, the M340DFT-PRO maintains a remarkably compact footprint. Its optimized design means you get the farthest-reaching beam of any SureFire long gun WeaponLight in a mini form factor, minimizing bulk and weight on your firearm. This compact size also contributes to better weapon balance and maneuverability, especially important in tight spaces or during prolonged use.

Versatility Redefined: The Low-Profile Mount (LPM) System

One of the most innovative features of the SureFire M340DFT-PRO Turbo Mini Scout Light Pro is its integrated Low-Profile Mount (LPM). This revolutionary mount system significantly enhances the adaptability of the WeaponLight, allowing users to precisely optimize its position to suit their specific setup and operational needs.

  • Unprecedented Positioning Freedom: The LPM design facilitates a wide range of mounting options, enabling the light to be tucked closely to the rail, reducing snags and maintaining a sleek profile. This flexibility means you can position the light exactly where it provides the best ergonomics and avoids interfering with other accessories like lasers, optics, or iron sights.
  • Broad Rail Compatibility: Whether your rifle features a MIL-STD-1913 Picatinny rail or an M-LOK system, the LPM ensures a secure and confident attachment. This dual-platform compatibility makes the M340DFT-PRO an exceptionally versatile choice for a wide array of modern sporting rifles, carbines, and shotguns, simplifying integration into existing weapon systems.
  • Easy and Secure Attachment: The LPM is engineered for quick, secure attachment and detachment, utilizing a robust interface that withstands recoil and harsh treatment without losing zero or shifting. This reliability is crucial in tactical applications where equipment failure is not an option.

Dual-Fuel Innovation: Powering Your Mission

The dual-fuel capability of the SureFire M340DFT-PRO is a significant advantage, offering unparalleled flexibility in power sources. This feature ensures that you can always keep your WeaponLight operational, regardless of battery availability or mission requirements.

  • Included SF18350 Rechargeable Battery: The M340DFT-PRO comes standard with SureFire’s high-performance SF18350 rechargeable lithium-ion battery. This option provides the highest output (95,000 candela) and offers the convenience and cost-effectiveness of rechargeability, making it ideal for regular training and prolonged use.
  • CR123A Primary Battery Compatibility: For situations where recharging isn't feasible or rapid deployment is critical, the M340DFT-PRO can also be powered by a single, widely available 123A primary lithium battery. While the candela output adjusts to 55,000 with this option, it still delivers powerful illumination and ensures you're never left in the dark.
  • Optimized Run Time: Depending on the battery choice, the M340DFT-PRO provides reliable run times ranging from 45 minutes to 1 hour. This duration is optimized to provide consistent, high-output illumination for critical engagement periods while maintaining the compact form factor.

Built for the Toughest Conditions: Durability and Reliability

When selecting a weapon light, durability is non-negotiable. The SureFire M340DFT-PRO Turbo Mini Scout Light Pro is constructed to SureFire’s legendary standards, ensuring it can withstand the harshest environments and the rigors of combat.

  • Aerospace-Grade Aluminum Construction: The body of the M340DFT-PRO is precisely machined from lightweight yet incredibly strong aerospace-grade aluminum. This material provides exceptional resistance to impact, corrosion, and extreme temperatures, ensuring the light maintains its integrity under stress.
  • Mil-Spec Hard Anodized Finish: The aluminum housing features a Mil-Spec (Military Specification) hard-anodized finish in black. This finish is not merely cosmetic; it provides superior scratch, abrasion, and corrosion resistance, protecting the light from the elements and wear and tear encountered during tactical operations.
  • O-Ring Sealed for Environmental Protection: To safeguard the internal components from moisture and dust, the M340DFT-PRO is meticulously O-ring sealed. This provides an IPX7 waterproof rating, meaning it can be submerged in water up to 1 meter for 30 minutes without adverse effects, making it impervious to rain, splashes, and accidental immersion.
  • Rugged and Reliable Performance: Every aspect of the M340DFT-PRO's design emphasizes rugged reliability. From its robust housing to its impact-resistant lens, it’s built to deliver consistent performance shot after shot, mission after mission. Its proven design minimizes potential failure points, providing peace of mind when it matters most.

Ergonomics and User Experience

The operational experience with a weapon light is as important as its raw performance. The SureFire M340DFT-PRO excels in user-centric design, integrating seamlessly into your firearm setup.

  • Intuitive Switch Types: The M340DFT-PRO offers versatility in activation with both push-button and tail cap switch options. This allows users to choose the activation method that best suits their grip, shooting style, and accessory configuration. The switch provides both constant-on and momentary activation modes, offering flexibility for various tactical scenarios.
  • Compact Dimensions and Lightweight Design: With an overall length of 4.80 inches and a mere weight of 5.11 ounces, the M340DFT-PRO adds minimal bulk to your firearm. Its compact head diameter of 1.258 inches also reduces the likelihood of snagging on gear or vegetation. This lightweight and streamlined design contributes to faster target transitions and reduced shooter fatigue.
  • Ambidextrous Operation: Designed for ambidextrous use, the M340DFT-PRO can be mounted and operated comfortably by both left- and right-handed shooters, ensuring universal accessibility and operational efficiency.
