Kelvin is the measure of the color temperature of a light source. You can tell from the value how warm or cool the light appears. Depending on the spectral composition, different shades of white result. 

The higher the Kelvin value, the cooler the color temperature. 

Basically, a distinction is made between three light colors:  

  • warm white light ≤ 3,300 K 
  • neutral white light 3,300 to 5,300 K 
  • cool white or daylight white light: ≥5.300 K

You can usually find the Kelvin value on the packaging of the illuminant or under "Technical data" in our store.
