For residential applications, LED lights with a CRI of at least 90 are recommended for bedrooms, living rooms, bathrooms, and kitchens. For business applications, lights with a CRI of 80 are suitable for general work in offices, while lights with a CRI of 97 are recommended for offices where work with colors is involved, as well as design studios and photography studios.

To understand the CRI color rendering index, we need a brief explanation of how sunlight is perceived as white.

Glass prisms are an easy experiment to visualize the composition of sunlight. It shows white light is a combination of different wavelengths in the electromagnetic spectrum.

To have white light from an artificial source, a mix of different emitted wavelengths is required. However, a close analysis of the white light of artificial lighting shows that not all white light is the same.
