CCT stands for Correlated Color Temperature. It refers to a measurement that describes the color appearance of light produced by a light source, primarily white light. CCT is an essential concept in lighting design and is commonly used to categorize different types of light sources based on their color temperature.
Color temperature is measured in Kelvin (K), where lower values represent warmer light with more yellow and red tones, and higher values indicate cooler light with more blue tones. CCT is used to describe the appearance of artificial light sources, such as incandescent, fluorescent, and LED lights, by comparing them to the color of a theoretical black-body radiator at a particular temperature.
For instance, a light source with a CCT of 2700K will emit warm, yellowish light similar to the color temperature of an incandescent bulb, while a light with a CCT of 6000K will produce cooler, bluish light closer to daylight or overcast sky tones.
CCT is important in various applications, such as interior lighting design, photography, cinematography, and even health-related studies. It helps designers and professionals choose the appropriate light source to create specific atmospheres or meet certain requirements for color rendering or visual comfort.
In summary, CCT is a quantitative measure that defines the color appearance of light produced by a light source and plays a significant role in determining the desired lighting effect.
