SureFire - M640DFT-PRO Turbo Scout Light Pro, Black or Tan

The SureFire M640DFT-PRO Turbo Scout Light Pro is designed with a Turbo Series reflector that focuses its beam to achieve high candela output. This allows it to generate a peak beam intensity of up to 100,000 candela, providing a tightly focused beam ideal for long-range target identification. This feature is particularly useful in tactical scenarios where identifying targets at a distance is crucial. However, users should be aware that while the beam is highly focused, it may not illuminate a wide area, which could be a limitation in close-quarters situations.

The dual fuel capability of the M640DFT-PRO allows it to operate on either the included SF18650B rechargeable battery or two 123A lithium batteries. This versatility ensures that users have options depending on availability and preference. The rechargeable battery offers longer runtime and higher output, making it ideal for extended operations. In contrast, the 123A batteries provide a convenient alternative when recharging is not feasible, such as in remote locations or during prolonged power outages.

The M640DFT-PRO is constructed from aerospace-grade aluminum with a Mil-Spec hard-anodized finish. This robust construction ensures the light is highly resistant to impact and environmental stressors. Additionally, the tempered window and O-ring seals provide IPX7 waterproof protection, making it suitable for use in wet and harsh conditions. However, while it is waterproof, it is important to note that it should not be submerged for prolonged periods.

The M640DFT-PRO offers a ZE68 momentary/constant-on pushbutton with a protective shroud. This design allows users to choose between momentary and constant-on modes, providing flexibility based on tactical needs. The protective shroud helps prevent accidental activation, which is crucial in stealth operations. Additionally, the light is compatible with a range of SureFire accessory remote switches, offering further customization for user preference.

The M640DFT-PRO is available in black or tan, offering users a choice based on their operational environment. The black finish is typically preferred for urban or low-light environments where blending into shadows is advantageous. The tan option is ideal for desert or arid environments where it can better match the surroundings. While color choice can aid in camouflage, it is essential to consider the primary operational setting to maximize the tactical advantage.

The M640DFT-PRO provides different runtimes depending on the battery used. With the SF18650B rechargeable battery, the light can run for approximately 2.75 hours at maximum output. In contrast, using two 123A lithium batteries, the runtime is about 1.75 hours. This difference is significant for users planning extended operations, as the rechargeable battery offers a longer duration of use. However, the convenience of 123A batteries can be beneficial when quick replacements are needed.

The M640DFT-PRO is designed to withstand adverse weather conditions, thanks to its IPX7 waterproof rating. 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 O-ring seals further enhance its resistance to moisture and dust. However, while it is robust against weather elements, users should avoid prolonged submersion to maintain its integrity.

The high-candela beam of the M640DFT-PRO, reaching up to 100,000 candela, is beneficial in tactical situations where long-range visibility is required. This intense beam can penetrate through smoke, fog, and other visual obstructions, providing clear target identification. It is particularly advantageous in search and rescue operations or when operating in low-light environments. However, the focused beam may not be suitable for illuminating large areas, which is a consideration for users needing broader coverage.
