Color Rendering Index (CRI)
CRI (Color Rendering Index) is a quantitative measure of how accurately an LED light source
can reveal the true colors of various objects compared to a natural light source. The higher the
CRI rating, the better the LED light source is at rendering colors as true and as accurate as
possible. True and brighter colors are revealed when a high CRI rated light is used. The
standard test for CRI is done using a representative set of colors most commonly found in
homes throughout the United States.
R9 Values
While CRI focuses on the measurement of 8 standard pastel colors under various light sources,
the R9 Value focuses exclusively on the color Red. But why Red? The color Red is found within
more processed colors than any other color in the visible light spectrum. The ability to precisely
reproduce the color Red is essential for accurately rendering the true colors of objects in your
home. LED lights with high R9 Values produce the most vivid colors and yield the finest quality
of light available today.
