What is CCT K?
Color temperature is a unit of measurement that expresses the color components contained in light. Theoretically speaking, the black body temperature refers to the color of the absolute black body after being heated from absolute zero (-273°C). If the light emitted by a light source has the same spectral components as the light emitted by a black body at a certain temperature, it is called a certain K color temperature. For example, the color of the light emitted by 100W led lighting is the same as the color of absolute black body at 2527°C, then the color temperature of the light emitted by this led lighting is: (2527+273) K=2800K.
The color temperature calibrated by this method is exactly the opposite of what the general public thinks of "warm" and "cold". For example, people usually feel red. Orange and yellow are warmer, and white and blue are colder. In fact, red has the lowest color temperature, and then gradually increases are orange, yellow, white, and blue, and blue is the highest color temperature.
Generally, Commercial Lighting, Office Lighting, and Retail Lighting use relatively high color temperature.
Home lighting is relatively warm.
There is also batten light that can change the color temperature.
