Colour temperature is a measure of how the different output of white lightbulbs are distinguished.
It reflects that the vast majority of an incandescent bulb’s light comes from thermal radiation – essentially the temperature of the filament indicates the colour of the light.
Because compact fluorescents and other lamps generate light by different processes, they are assigned a Correlated Colour Temperature which indicates how the human eye would perceive it.
Low temperatures are “warmer”, with a yellow tinge that makes them suitable for home lighting. The higher temperatures are bluish-white – suitable for task lighting.
At the Lamp Company, we indicate the colour temperature in our compact fluorescent part codes by the following abbreviations:
|82||2700K||Very Warm White|
