Emitter	4 x Cree XHP35 HI LEDs
Color temperature	6500 K
Reflector	SMO
Lens	toughtened AR coated glass
Switch	dual electronic side

The emitter of TK75 manufactured by Cree, a US-based LED manufacturing company. Cree is a well-regarded LED manufacturer known for its high-quality products and innovation in the lighting industry. Color temperature is a characteristic of light. It is measured in units called Kelvin (K) and is used to quantify the color appearance of light sources, particularly white light. The TK75 has a smooth reflector. The properly focused smooth reflector gives you a more cohesive hotspot and therefore throws better.

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 TK75 utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches.

Performance

Flux	5100 lm
Intensity	180600 cd
Throw	850 m
CD/LM factor	35.41

With 5100 lm, the TK75 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. 180600 cd represents an extremely high level of brightness for a flashlight. 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	6 modes
Mode memory	yes
Ramping mode	no
Strobe	yes
SOS/Beacon	yes

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The TK75 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 TK75 is tactical strobe ready. The strobe light is disorienting to the person it is aimed at which makes it difficult for them to concentrate. It has the SOS beacon function for an emergency situation. The SOS flashes Morse code so you can signal for help when needed. The SOS signal is recognized as an international distress call and is used to indicate an urgent need for assistance.
