Colour Temperature

Colour temperature in lamps refers to how warm or cool the color is. 


The warmth of light is measured in Kelvin; the lower the Kelvin rating, the more reddish the hues, and the higher the rating, the bluer the hues.


Indicatively, lights with 3000 Kelvin are usually recommended for fog lights, lights with 4300-5000 Kelvin are usually recommended for driving lights, and from 6000 Kelvin and above are for a more distinctive style.
