Answered by pushpakRuhil

the natural light we receive is generally from stars! which are hot, coz they have a high temperature due to the combustion and reactions ongoing their, it causes luminosity in tube lights, we have some sort of gas present in it which don't have a high temperature and still gives us light. so it's called the cold source of light.

hence your statement is TRUE.

pushpakRuhil: though the temperature rises not due to the gas but due to resistance.

pushpakRuhil: we notice that old bulbs used to get much hotter than the CLFs present today.
