Abstract
A dimmer and an illumination apparatus are connected by a two wire circuit. The dimmer energizes the illumination apparatus and provides control of the illumination apparatus via the two wire circuit. The illumination apparatus receives all of its energization and control from the two wire circuit. Multiple strings of multiple color light emitting devices are switched on in a partitioned order during flank intervals of a switched AC power envelope on the two wire circuit.
