    Abstract: The present disclosure provides intelligent lighting control systems. The lighting control system apparatuses include a light control module configured to be coupled to a luminaire electrically coupled to a light bulb comprising a capacitor. The lighting control module comprises a controller configured to temporarily close a circuit comprising a load wire configured to connect an AC power source to the capacitor through the luminaire, whereby electricity flowing through the load wire flows through the capacitor in the light bulb and charges an energy storage device in the lighting control module electrically coupled to the load wire. The controller is configured to after temporarily closing the circuit, re-open the circuit prior to the capacitor fully charging, so as to prevent a light emitting element of the light bulb electrically coupled to the capacitor from illuminating.
