ABSTRACT:
A lighting system comprising: an AC power line; an electronic ballast including structure for receiving and interpreting commands transmitted on the power line to control dimming of a fluorescent lamp, the ballast including structure defining an individual address, the ballast including structure for initiating an arc to start the fluorescent lamp, for limiting current through the fluorescent lamp after the arc is initiated, and for dimming the light output of the fluorescent lamp; and a control element spaced apart from the electronic ballast and including structure for sending commands on the power line in a format that the ballast is capable of interpreting, the control element including structure for sending an address with the command, the ballast including structure for comparing the sent address with its individual address and responding to the command if the sent address matches its individual address.
