UNDERSTANDING THE R9 COLOR RENDERING VALUE
Color Rendering Index (CRI) is a rating system that measures the accuracy of how well a light source reproduces the (total) color of an illuminated object. CRI is an average value based on R1 - R8. R9 is one of 6 saturated test colors not used in calculating CRI.
Since some percentage of the color Red can be found mixed into the various hues of most processed colors,the ability to accurately reproduce Red is key for accurately rendering colors of displayed objects. Lamps with highR9 values produce the most vivid colors.
