Classification: CPC H | IPC H

Claim 1:
2. The electric load control system of claim 1, the electric load controller control circuitry to further:
receive an input that includes information indicative of an output luminous intensity of an operatively coupled electric load device that includes one or more light-emitting diodes (LEDs); and
determine whether the received output luminous intensity of the one or more LEDs is at or above a first threshold luminous intensity;
responsive to the determination that the received output luminous intensity is at or above the first threshold luminous intensity:
receive a second voltage sense output signal, the second voltage output signal indicative of a voltage across and a current through a primary winding of the transformer included in the load regulation circuitry;
determine an input power supplied to the primary winding of the transformer;
retrieve from memory circuitry data representative of an efficiency of the load regulation circuitry; and
determine a first average load current delivered to the one or more LEDs using the determined first load current, the retrieved efficiency of the load regulation circuitry, and the determined input power of the load regulation circuitry.
