Managing solid-state luminary (SSL) fixtures over power line carrier (PLC) networks is described herein. Devices provided in this description include SSL arrays, and converter circuitry coupled to drive the SSL arrays. More specifically, the converter circuitry is adapted to convert input voltage received from a power distribution network into a level suitable for driving the SSL arrays. The devices also include (PLC) modems for coupling to PLC networks, and coupled to the converter circuitry. In particular, the PLC modems interface the converter circuitry to the PLC networks.
