Correlated Color Temperature (CCT) is a measure of the color appearance of light emitted from a light source, typically a light bulb or LED. It is measured in Kelvin (K) and is used to describe how “warm” or “cool” the light appears. Lower CCT values, such as 2200-3000K, are considered “warm” and emit a yellowish-white light similar to the glow of a candle or incandescent bulb. Higher CCT values, such as 5000-6500K, are considered “cool” and emit a bluish-white light similar to daylight. The CCT of a light source can have a significant impact on the look and feel of a space, as well as on the perceived color of objects within that space.
