    Abstract: An electronic ballast circuit for powering a gas discharge lamp is networked with other ballast circuits to provide large scale lighting control on a local or remote basis. The ballast has an interface connectable to a standard PC for receiving commands and obtaining query information. The ballasts can be controlled individually or in groups. The ballast control also can download lighting profiles to a microcontroller in the ballast, and can support lighting control protocols including the DALI standard.
