A universal lighting source controller including integral power metering for use with substantially all light source types including fluorescent, incandescent, magnetic low voltage, electronic low voltage, light emitting diode (“LED”), high density discharge (“HID”), neon, and cold cathode. The lighting source controller includes a line voltage dimming circuit that can control the intensity of light sources in a lighting circuit and measures the actual amount of power consumed by the light sources. The line voltage dimming circuit includes a triac circuit for controlling this intensity and current and voltage detection circuits for measuring the power consumption. The lighting source controller can also include low voltage dimming circuits to provide a control signal to light sources having electronic or magnetic dimming ballasts to set the intensity of these light sources. 1. A lighting control system , comprising:a lighting control circuit of a plurality of lighting control circuits operable to receive a control signal comprising a command to energize a light source and allow electrical energy to flow to the light source in response to the command;a panel controller communicably coupled to the plurality of lighting control circuits, wherein the panel controller is operable to transmit the control signal to the lighting control circuit; and a first meter operable to measure a first power usage of a first portion of the lighting control circuit; and', 'a second meter operable to measure a second power usage of a second portion of the lighting control circuit,, 'a power metering circuit communicably coupled to the lighting control circuit and comprisingwherein the lighting control circuit is electrically coupled to the light source,wherein the lighting control circuit is operable to control the light source and the at least one other light source,wherein the first power usage and the second power usage are made available to a building management system,wherein the ...
