Abstract
Improvements to lighting systems, especially for entertainment and architectural applications are disclosed, including apparatus that permit a user to readily field-configure power distribution to branch circuits to be dimmed or un-dimmed, single- or multi-phase, as required; communication of data over existing power wiring by variations in output of dimmers; and improved methods for generating, managing, and distributing data specifying the physical and electrical configurations of a lighting system.
