Historically, power distribution has been dominated by Alternating-Current (AC) which significantly influenced the design of connected energy-consuming appliances.  With the emergence of electronics and digital controls as standard design elements in almost all appliance categories, the need for Direct-Current (DC) has emerged, even as it opposes traditional distribution practices.  This issue is typically resolved at the appliance level with AC-to-DC converters.

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.
