What is Kelvin temperature on a lamp and what does it mean?
Kelvin is a measure of the color appearance of a light source which helps describe the apparent “warmth” (reddish) or “coolness” (bluish) of that light source. Generally, light sources below 3200K are considered “warm;” while those above 4000K are considered “cool”. The color temperature of a lamp has nothing to do with how hot the lamp will get or how much heat is given off by the lamp. The letter, K, stands for Kelvin.
