In an example, a light control system includes a power converter, a light source, a sensor, and a control device. The power converter can convert an input power received from a power source to a supply power, and includes a power factor corrector (PFC) configured to adjustably control an electrical parameter of the supply power. The light source can, using the supply power, emit light at an intensity related to the electrical parameter. The sensor can sense a condition related to operation of the light source. The control device is communicatively coupled to the PFC and the sensor, and configured to: (i) receive, from the sensor, a sensor signal indicating an input parameter related to the condition, and (ii) based on sensor signal, provide a feedback signal to the PFC to cause the PFC to adjust, based on the input parameter, the electrical parameter of the supply power.
