Correlated Color temperature (CCT) is a characteristic of emitted visible light, defined as the temperature of an ideal black-body radiator that radiates light of comparable hue to that of the light source. It is measured in Kelvin (K). Lower temperatures (2,700-3,000 K) are called warm colors (yellowish white through red), and higher temperatures (5,000+ K) are called cool colors (bluish white). Color Tuning refers to a change in the color temperature of white light, or the shade of white light. Traditionally it was done using added color filters or with separately-controlled warm and cool light fixtures.
LEDs have made color tuning simpler than that done with conventional lights. Color Tuning can now be done through a single LED light fixture; it can even be done in a small 2″X3″ LED can light. Color Tuning fixtures are often used for simulating daylight conditions. They are also commonly used for displays such as in jewelry stores where different jewelry items might look better under different color temperatures. Color Tuning fixtures are also very useful with cosmetics counters, in photography studios, or on movie sets. Please contact us to learn more about color tuning applications with LED products.
