Färgindex
Färgindex, often abbreviated as CRI (Color Rendering Index), is a quantitative measure of the ability of a light source to reproduce the colors of various objects faithfully compared to a natural light source, such as sunlight. It is a crucial parameter when evaluating the quality of artificial lighting, particularly in applications where accurate color perception is important.
The CRI scale ranges from 0 to 100. A CRI of 100 indicates that the light source
The evaluation involves observing the appearance of eight standard pastel-colored test samples under the light source
