Is there anything like cold or warm light? Everything in this world has a temperature, What about light?
Blackbody radiation is defined as radiation that is in thermal equilibrium. Therefore it has a temperature. Other types of radiation do not have a well-defined temperature, by definition.
When an object gets really hot it starts to give off visible and uv light, and an increased amount of IR. Color scientists used the term colour temperature to compare the colour of light to a known black body standard (you can google D65). A lot of cheaper led lights are 5000K which is blueish, the more expensive and slightly less efficient led bulbs are 3000K and are reddish closer to natural light. The 3000 Kelvin is the about the same color as a blackbody at 3000K.
But light does not have temperature like matter does which is mass and kinetic energy.
