The temperature of the ideal emitter that matches the color most closely is defined as the color temperature of the original visible light source. The color temperature scale describes only the color of light emitted by a light source, which may actually be at a different (and often much lower) temperature. [1] [2]
The Kelvin scale is an absolute temperature scale that starts at the lowest possible ... The kelvin is often used as a measure of the colour temperature of light sources.
The higher the kelvin rating, the colder the color temperature. Bright or cool white light ranges from 7,000K to 10,000K. This light is great in dimly lit spaces like garages , attics, and work sheds.

Many scientific measurements use the Kelvin temperature scale (unit symbol: K), named in honor of the physicist who first defined it. It is an absolute scale. Its numerical zero point, 0 K, is at the absolute zero of temperature. Since May 2019, the kelvin has been defined through particle kinetic theory, and statistical mechanics.
This definition also precisely related the Celsius scale to the Kelvin scale, which defines the SI base unit of thermodynamic temperature with symbol K. Absolute zero, the lowest temperature possible, is defined as being exactly 0 K and −273.15 °C. Until 19 May 2019, the temperature of the triple point of water was defined as exactly 273.16 ...
A black body is characterized by its temperature and emits light of a specific hue, which is referred to as color temperature. [ 3 ] [ 4 ] [ 5 ] In practice, light sources that approximate Planckian radiators, such as certain fluorescent or high-intensity discharge lamps, are assessed based on their CCT, which is the temperature of a Planckian ...
