|Color Rendering Index:
The Color Rendering Index (CRI) is a relative scale to determine a light source’s ability to render an object’s color. The higher the number, 100 being the best, the better the color rendering. Specify a source that has 90+ where color matching/selection is occurring; 80+ for pleasant appearance of people, food and merchandise; 70+ for offices, educational, health care and institutional settings; 50+ for most industrial tasks.
Color Temperature is measured in Kelvin and represents whether the light source appears warm (1,500K), neutral (3,500K), cool or daylight (5,500K). The chart below highlights the color temperature and how it affects the mood of the space.
