Kelvin / Color Temperature
KShort definition
Expresses the warmth of light, measured in Kelvin (K). Low values (2700K) give warm/yellow light, high values (4000K+) give cool/white light.
In detail
Color temperature directly shapes atmosphere. 2700–3000K warm tones suit homes, restaurants and hotels. 4000K neutral white supports focus in offices, stores and schools. 5000K+ daylight tones are used mostly in technical and industrial spaces.
