What is Colour Temperature?
Colour temperature is the appearance of light emitted from a fixture in varying hues of whites and is measured in degrees of Kelvin (K) on a Correlated Colour Temperature (CCT) scale from 1,000 to 10,000.
If you’ve ever worked with photography, then you may already be familiar as lighting is often categorized in warm and cool tones. For example, light at 2000K-2500K can appear more orange and yellow (called ultra warm white) and is a nice accent to use as decorative lighting for a vintage feel. As the temperature increases in Kelvins, light become whiter at around 3000K making natural light. Any luminance above 4000k becomes a blue-ish, cool white. st the warmth of the white with a simple switch on the fixture.
