Decoding Flashlight Light: Understanding CCT and CRI
/
Understanding CRI (Color Rendering Index) and CCT (Correlated Color Temperature) is essential for selecting the right lighting. CRI measures how accurately a light source reveals the true colors of objects compared to natural light, with a scale from 0 to 100—higher values mean better color accuracy. CCT describes the color appearance of the light itself, measured in Kelvins (K). Lower CCT values (around 2700K) produce warm, yellowish light, while higher values (5000K and above) yield cooler, bluish tones. Together, CRI and CCT help ensure lighting is both visually appealing and functional for any space.
