An LED lighting system comprises an elongated linear lamp having an LED luminary as a source of illumination and configured to operate as a node of an automated networked lighting system. The lamp comprise an elongate multi-sided heat sink having first and second LED emitter panels mounted thereon for distributing light outwardly from the emitter panel. A first end cap assembly at the first end of the lamp body houses a communications jack having an internal port for providing an interface operable to transmit power and data signals. The first end cap assembly defines a first opening allowing a network communications plug to be received through the access opening into the internal port of the jack. The linear lamp is operable to receive control data and power signals according to a standardized power and data network communications architecture such as Ethernet.
