KnowraCorrelated color temperatureLinked fromLinked fromThe 9 pages that link to Correlated color temperature, each with the reason it gives.All 9Broader topic 1Related 7Compared with 1Light pollutionRelated: Choosing warmer sources can reduce short-wavelength emissions associated with greater skyglow and biological effects.Spectral power distributionRelated: CCT summarizes an SPD's warm-or-cool appearance with a single Kelvin number.Color rendering indexRelated: It helps determine which reference illuminant CRI uses.Luminous efficacyRelated: It describes perceived color appearance, not light output per unit power.Dark-sky preservationRelated: Warmer light can reduce short-wavelength emissions that scatter strongly in the atmosphere.Illuminant (colorimetry)Related: How non-Planckian illuminants like daylight series and fluorescents get their Kelvin ratings.Standard illuminantRelated: Illuminants are often specified and compared by their CCT rather than their full spectrum.
