With the Kelvin scale, you can describe the temperature of a given light on a scale from 0 to 10.000. The amount of Kelvin affects our body, hormonal balance, and circadian rhythm. It can make us feel energised or tired, happy or sad.
Choosing the lighting temperature should always be based on the purpose of the light and the room. A high amount of Kelvin, a more cold and blue light, helps us stay more productive throughout the day. However, it also makes it difficult for us to calm down before going to sleep. On the other hand, while a low amount of Kelvin, a warmer and more orange colour, is relaxing, it is insufficient lighting for offices and stores.
No lighting fits all spaces, and the same goes for the amount of Kelvin. It needs to be adjusted according to the room and its function to ensure optimal efficiency and human well - being.
