Studying Chromaticity Binning: What should we Expect from Today's LED Light Sources?

Generally, people expect two light sources with the same rated color appearance to appear identical when installed in their homes and businesses. Obvious variation often leads to dissatisfaction, complaints and product returns. To avoid these issues, it is important that light sources have sufficient chromatic consistency to ensure color matching for most people. Currently, the lighting industry relies on binning for correlated color temperature (CCT) and Duv to address this issue.
