The color temperature (Kelvin [K]) of an LED can be divided into three categories. We speak of a warm white LED at a color temperature of up to approx. 3,200K/3,500K. From 3,500K to approx. 5,000K we speak of neutral white light. From 5,000K we speak of daylight white or cool white.
However, the boundaries between the different color temperature ranges are fluid and not fixed. In industry, spotlights with 5,000K are mostly used because the cool light and its activating effect on people can prevent accidents at work. The higher the color temperature or the colder the light color, the more activating the light is for people.
