Kelvin (K) is the unit that indicates the colour temperature of a light source. The less kelvin, the warmer the light colour. The more kelvin, the colder the light colour.
At psmlighting we make a distinction between three types of colour temperature:
- Warm white: 2700K - especially for atmospheric lighting in homes, restaurants and hotels.
- Neutral white: 3000K - often in shops, showrooms and as general lighting in offices.
- Cold white: 4000K - cool light increases concentration and is therefore most often used in offices, warehouses and industrial work environments.
