Abstract

Remote lighting control methods, devices and systems are disclosed. One embodiment of the present invention pertains to a light device. The light device includes a light source for emitting light and a control circuit for setting an intensity level of the light source based on receipt of control data via a power line when the light device is electrically coupled to the power line. The control data is generated in response to user input to an input panel of a remote lighting control module for the light device. In addition, the light device comprises a unique address associated with a region on the input panel.
