How about light color temperature - Apply to sports field lighting

When learning about lighting equipment, we need to consider many different quantities. Besides the power factor, protection level or color rendering index, the light color temperature is also an important factor.

What is the nature of the light color temperature?

First of all, this value does not represent the actual temperature of the light source. Scientists use the Kelvin unit (K) to measure this quantity. So how is the term light color temperature understood? This value reflects the color of the light emitted at a particular K temperature. An example is the experiment of burning a black iron. At a certain temperature, the iron bar glows. The strongest color of light the iron emits is related to its temperature. This is related to Planck's law of radiation.
