Color temperature describes the warmth or coolness of a light source. It's measured in Kelvin degrees on a scale of 1,000 to 10,000. Certain color temperatures are superior for specific tasks. For example, white light sources with a color temperature between 3500-5500 Kelvin are most appropriate for bathroom task lighting.
