What does CRI stand for in lighting?

The correct choice refers to the Color Rendering Index. This is a significant metric within lighting design, as it measures a light source's ability to accurately reproduce the colors of objects in comparison to a natural light source. The CRI scale ranges from 0 to 100, with higher values indicating better color accuracy and more vibrant color representation. This is particularly important in spaces where true color visibility is crucial, such as in art studios, retail environments, or any setting where aesthetics and visual fidelity are prioritized.

Understanding the Color Rendering Index helps designers choose the appropriate lighting for specific applications, ensuring that the colors of materials and features are perceived as intended. This knowledge contributes to creating visually appealing and functional spaces, underscoring the importance of CRI in effective interior design and lighting applications.
