When a product is marked as CCT it means that the colour temperature can be changed. CCT is defined in degrees Kelvin, according to the colour perception of a white LED to the human eye, we can differentiate them into 3 types of colour; warm white, daylight and cool white, which range from 2700-3500K, 4000-4500K and 5000-6500K. The CCT values do not indicate anything about the colour rendering ability of the LED.
