The Definition and Importance of CRI in Lighting
Color Rendering Index (CRI) is a key metric that evaluates how accurately a light source reveals the true colors of objects, with a perfect score being 100. The higher the CRI, the more closely the light source mimics natural daylight in rendering colors. Different applications have varying CRI requirements. For instance, supermarkets and retail stores typically demand a CRI above 80 to ensure products are displayed in their true colors, enhancing customer appeal. On the other hand, industrial and street lighting generally requires a CRI around 70, where brightness and energy efficiency are prioritized over color accuracy.
