It's important to consider personal comfort and intended use when selecting a flashlight, as a heavier flashlight may be more tiring to hold for extended periods or less suitable for activities that require lightweight portability. The ideal length of a flashlight depends on personal preference, intended use, and the specific features and functionality you're looking for. Aluminium body of TM10K 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 process produces a hard and wear-resistant surface on the aluminum, making it more resistant to scratches, abrasions, and impacts. This improves the overall durability of the flashlight body. The TM10K flashlight is available in black.

Cree is widely regarded as a reputable LED manufacturer and has a track record of delivering high-quality and innovative lighting solutions. 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 TM10K 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.

Throw283 m
CD/LM factor2

With 10000 lm, the TM10K 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 TM10K flashlight with 20000 cd has an extended throw distance, allowing you to illuminate objects or areas at greater distances. This can be advantageous for outdoor activities, search and rescue operations, or scenarios where long-range visibility is required.

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.


Modes5 modes

Ramping modeno

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The TM10K 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 power source of the TM10K flashlight is integrated 21700 Li-Ion battery, 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.

This flashlight can charge the battery with an integrated charger, and it works with a USB power source. When the TM10K 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 TM10K 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.


Package contentsUSB Type-C cable
nylon holster

The package includes a holster to safely store your flashlight. The lanyard of TM10K helps protect the flashlight from accidental damage by preventing it from falling or hitting the ground.

The performance of the Nitecore TM10K 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.
