Abstract

The present disclosure provides apparatuses and methods for measuring power for a lighting control system. The includes a lighting control module configured to cause a transmission of a quantity of electrical power to a lighting circuit of a light fixture electrically connected to the lighting control module, a detector circuit positioned in the lighting control module, and a controller in electrical communication with the detector circuit. The controller is specially programmed to correlate a quantity of electrical power transmitted to the lighting circuit to the response of the lighting circuit. The controller is further programmed to determine a power correction factor based on the correlation between the quantity of electrical power transmitted and the response. The power correction factor is configured to alter the response of the lighting circuit to a predetermined value.
