Infographic: What does 3CCT mean in LED lighting?

3CCT means that an LED lamp or luminaire has three selectable colour temperatures, usually 3000 K (warm white), 4000 K (neutral white) and 6000 K (daylight). CCT stands for Correlated Colour Temperature, the light colour in Kelvin. You select the desired colour with a small switch on the luminaire, a remote control or by briefly switching the light switch off and on.
