LED lighting is often controlled by dimmers. As lighting power is reduced, an overall correlated color temperature (“CCT”) of the lighting may change. The CCT may be based on a ratio of power distributed to high CCT lighting elements and low CCT lighting elements. Different ratios may provide different overall CCT of the lighting. Different users may have different preferences for the CCTs at different lighting power levels. In particular, different users may have different preferences for the overall CCT at dimmed lighting levels.
It would therefore be desirable to provide apparatus and methods for providing different CCT at dimmed lighting levels.
