Abstract

A luminaire can include a power supply that receives AC mains power from a power source and delivers intermediate power. The luminaire can also include a control module coupled to the power supply, wherein the control module receives the intermediate power from the power source, where the control module includes at least one first switch that has multiple positions, where each position of the at least one first switch corresponds to an output power level of a plurality of output power levels. The output power level can correspond to a discrete correlated color temperature (CCT) output by a plurality of light sources of the luminaire.
