Learn More about R9 and CRI

Brief Introduction
The color rendering index (CRI) and R9 are two important elements to consider when selecting the flexible LED strip or the necessary accessories. This can be essential for contractors and distributors that best meet customer needs. Nowadays, color quality is an important factor in the evaluation of LED lighting for commercial and residential applications.


What R9 and CRI means?
To define the term R9, first of all, it is important to understand what the color reproduction index is. The color rendering index is a classification system that measures the precision with which a light source produces the color of an illuminated object. Measures the ability of the light source to display colors of "tactile" or "normal" objects, compared to a familiar reference source, be it daylight or incandescent light. The color rendering index is an average based on R1 to R8. R9 is one of six saturated test colors that are not used to calculate the CRI.
