Correlated Color Temperature
The color temperature of a LED light source is determined by comparing its chromaticity with that of an ideal black-body radiator. The temperature, usually measured in Kelvin (°K) at which the heated black-body radiator matches the color of the light source is that source’s color temperature; for a black body source, it is directly related to Planck’s law. Yellow-red colors are considered warm, and blue-green colors are considered cool.
Higher Kelvin temperatures are considered cool and lower color temperatures are considered warm (as highlighted in the following diagram). Cool light produces higher contrast while warm light is preferred for living spaces because it is considered more flattering to skin tones and clothing. Cantalupi specializes in customizing and controlling these LED color temperatures providing customers with full control over their desired atmosphere.
