Nitecore TM39 (TM39) specifications

Flashlights are compact and lightweight, making them highly portable. They can easily fit into pockets, backpacks, or glove compartments, allowing you to carry them wherever you go.

Body

The TM39 generally comfortable to hold for extended periods and easy to carry in pockets or bags. The length of the TM39 flashlight can affect its portability. A shorter flashlight is generally easier to carry in a pocket, bag, or pouch, making it more convenient for everyday use or when you're on the go. Aluminium body of TM39 is known for its durability and strength. It offers excellent resistance to impacts, scratches, and corrosion, making it suitable for rugged outdoor use or in demanding environments.

The HAIII coating often has a matte or textured finish, which enhances grip and provides a comfortable feel in the hand. This can be particularly useful in situations where a secure grip on the flashlight is essential, such as in wet or slippery conditions. The TM39 flashlight is available in black.

System

Luminus has established a positive reputation as a reliable LED manufacturer, and their products are widely used and trusted by lighting professionals and enthusiasts alike. Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. The primary function of the smooth reflector (SMO) is to precisely focus and project the light emitted from the light source into a defined beam pattern. The smooth surface allows for greater reflectivity and light concentration, resulting in a more focused and intense beam with a longer throw distance.

This flashlight has an AR coated lens. This Anti-Reflective coating is a thin optical coating applied to the surface of the lens to minimize reflections and improve light transmission. The TM39 has electronic switch. The electronic switches may have a higher likelihood of standby drain compared to mechanical switches since they require a small amount of power for operation.

Performance

With 5200 lm, the TM39 flashlight will provide an exceptionally bright and powerful beam of light. It can illuminate large areas, outdoor spaces, or even act as a temporary spotlight in certain situations. The TM39 is a 562500 cd flashlight. Flashlights with extremely high luminous intensity often require significant power and generate more heat due to the increased energy output. The throw is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. The cd/lm factor (candela-to-lumen ratio) provides information about how concentrated or focused the light output of a light source is. A higher cd/lm ratio indicates that the light is more concentrated in a specific direction, while a lower ratio indicates a more diffused or spread-out light output.

Software

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The TM39 has mode memory. Mode memory means that the flashlight will remember the mode you were using when the light was last turned off, and when you turn it on again. The strobe function on the TM39 flashlight is a feature that produces a rapid and repetitive flashing of light. It is designed to create a disorienting or attention-grabbing effect. The TM39 has an SOS signal mode. The SOS code consists of three short signals, followed by three long signals, and then three short signals again.

Features

The power source of the TM39 flashlight is 1 x NBP68HD Li-Ion battery pack, providing reliable and long-lasting energy for optimal performance. Having a battery indicator on a flashlight is beneficial as it allows users to monitor the battery status and make informed decisions regarding recharging or replacing the battery. It helps prevent unexpected power failures during critical situations and ensures that the flashlight is ready for use when needed.

When the TM39 flashlight detects that the voltage of the battery has dropped to a certain threshold, it automatically reduces or cuts off the power output to prevent further discharge. This helps to preserve the battery's capacity and prevent it from reaching a critically low voltage level. The built-in thermal control automatically adjusts brightness output to prevent overheating. The "6" in the IP68 rating represents the level of protection against solid objects, specifically dust and foreign particles. It indicates that the TM39 flashlight, is fully protected against the entry of dust and other solid objects. The "8" in the IP68 rating indicates the highest level of protection against water ingress.

Accessories

The lanyard prevents accidental loss of the flashlight. Having spare O-rings allows you to replace them as needed, ensuring that the flashlight maintains its water-tight seal and remains protected from moisture or water ingress.

The performance of the Nitecore TM39 flashlight is measured according to the ANSI / NEMA FL1 Standard 30 seconds after switching the light on. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.

The specifications above are based on the official data published by the manufacturer, but we also take user reviews into consideration. If you found an error or something lacking in the specifications above for the Nitecore TM39, then don’t hesite and signal the problem to us.
