Claim 13:
14. The non-transitory, machine-readable, storage device of claim 13 wherein the instructions, when executed by the electric load controller control circuitry, further cause the electric load controller control circuitry to:
determine whether the luminous output of the one or more LEDs is at or above a first threshold luminous intensity; and
responsive to the determination that the luminous output of the one or more LEDs 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 disposed in the load regulation circuitry;
determine an input power supplied to the transformer disposed in the load regulation circuitry;
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, the input power supplied to the primary winding of the transformer.
