A method of driving a light source by a light driver includes measuring a current output signal of the light driver, calculating a percent change in output signal, determining whether the percent change in output signal is greater than or equal to a first threshold, and in response to determining that the percent change in the output signal is greater than or equal to the first threshold, calculating a percent change in reference voltage based on a current reference voltage and a previous reference voltage, determining whether the percent change in reference voltage is less than a second threshold, and in response to determining that the percent change in reference voltage is less than the second threshold, deactivating filtering and averaging of a dimmer signal received from a dimmer for a period of time, and reactivating the filtering and the averaging of the dimmer signal.
