Surefire - M340DFT-PRO Mini Scout Light, Dual Fuel

The Surefire M340DFT-PRO Mini Scout Light can operate on two types of batteries, offering flexibility in power sources. It can use the included SF18350 rechargeable lithium-ion battery to deliver 650 lumens with a peak beam intensity of 95,000 candela, or a 123A lithium primary battery for 350 lumens and 55,000 candela. This dual fuel capability ensures that you can rely on the light in various scenarios, whether you have access to rechargeable power or need to use disposable batteries. This adaptability is particularly useful in extended field operations where power sources may be limited.

The high-candela beam of the M340DFT-PRO is designed to provide a concentrated and far-reaching light pattern. With a peak beam intensity of up to 95,000 candela, this light can illuminate targets at long distances, up to 616 meters with the SF18350 battery. This feature is crucial for tactical situations where identifying threats or targets from a distance is necessary. However, the focused beam may not be ideal for close-quarters scenarios where a wider spread of light is preferred to illuminate a broader area.

The M340DFT-PRO features a Low-Profile Mount (LPM) that is compatible with MIL-STD-1913 or M-LOK rails. This allows for optimal positioning of the light on a variety of firearms, enhancing its versatility. The LPM ensures that the light can be securely attached without interfering with other rail-mounted accessories. This is particularly beneficial for tactical setups where space on the rail is limited and multiple accessories are needed.

The Surefire M340DFT-PRO is designed to withstand harsh weather conditions, meeting IPX7 waterproof standards. This means it can be submerged in water up to 1 meter for 30 minutes without damage, making it reliable in rain or wet environments. The rugged construction, including an aerospace aluminum body and Mil-Spec hard-anodized finish, further ensures durability. However, while the light is waterproof, it is not intended for prolonged underwater use.

The M340DFT-PRO offers versatile activation options to suit different tactical needs. It includes a ZE68 momentary/constant-on pushbutton with a protective shroud, allowing for quick and secure light activation. Additionally, it is compatible with SureFire accessory remote switches, which can be particularly useful for users who prefer to control the light without altering their grip on the firearm. This flexibility in activation methods enhances the light's usability in various operational contexts.

The dual fuel capability of the M340DFT-PRO is a significant advantage in tactical operations where power source flexibility is crucial. Being able to switch between a rechargeable SF18350 battery and a disposable 123A lithium battery means the light can be adapted to different mission durations and environments. This is particularly beneficial in situations where access to charging facilities is limited, allowing operators to carry spare disposable batteries as a backup.

The runtime of the M340DFT-PRO varies depending on the battery used. With the SF18350 rechargeable battery, the light can operate for approximately 45 minutes at 650 lumens. Using a 123A lithium battery, it can run for about 1 hour at 350 lumens. These runtimes are suitable for short to medium-length operations, but users should plan for battery replacements or recharges during extended missions. It's important to consider the trade-off between brightness and runtime when choosing your power source.

The Surefire M340DFT-PRO Mini Scout Light is a versatile tool for enhancing preparedness in emergency scenarios. Its high-candela beam provides excellent long-range visibility, which is crucial in both tactical and search-and-rescue operations. The dual fuel capability ensures that the light remains operational even if one type of battery is unavailable. Additionally, its rugged construction and waterproof design make it reliable in adverse conditions, whether in urban environments or wilderness settings.

The M340DFT-PRO Mini Scout Light is available in two color options: Black and Tan. These color choices allow users to select a finish that best suits their operational environment or personal preference. Black is often preferred for its low visibility in night operations, while Tan may be chosen for desert or arid environments where it blends better with the surroundings. The choice of color does not affect the light's performance or durability.

The protective shroud on the M340DFT-PRO's pushbutton is designed to prevent accidental activation. This feature is particularly useful in high-stress situations where inadvertent light activation could compromise tactical operations. The shroud ensures that the light is only turned on when intentionally pressed, providing users with greater control over their illumination. This design consideration enhances the overall reliability and effectiveness of the light in critical scenarios.
