It is measured in units called Kelvin (K) and is used to quantify the color appearance of light sources, particularly white light. A TIR lens works on the principle of total internal reflection. The TIR lens collimates the LED light into efficient, well-controlled light beams that maximize the usable lumens in the target area. The K3 Lite utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches.

CD/LM factor4.55

550 lm can provide a decent amount of brightness and be suitable for many everyday tasks, it may not be sufficient for certain scenarios or individuals with specific requirements. With 2500 cd, the K3 Lite flashlight provides a noticeably brighter and more intense beam of light. It can illuminate objects or areas with greater clarity and visibility, even at longer distances. 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.
