Les fluorescents compacts ont un IRC de 82 (sur 100), ce qu'on estime excellent pour les sources fluorescentes et bon pour l'éclairage artificiel en général. Par comparaison, l'IRC des ampoules à incandescence est de 97. Les ampoules à incandescence offrent un excellent rendu des couleurs car la lumière qu'elles produisent est constituée de longueurs d'onde couvrant la totalité du spectre visible. 4, record 2, French, - indice%20de%20rendu%20des%20couleurs

Basically, colour temperature describes the colour appearance of a light source. Sources with low colour temperature (below 3000 K) are described as "warm," and lean towards the red side of the spectrum. High colour temperature sources (above 4 000 K) are more bluish and are described as "cool". 2, record 3, English, - apparent%20colour
