A circuit for dimming a light emitting diode is provided. The circuit includes an alternating current input voltage that is delivered to a light emitting diode. The circuit also includes a correction circuit configured to monitor the input voltage, which also delivers a current to the light emitting diode, wherein the current delivered to the light emitting diode is commensurate with the input voltage. The circuit also includes a simulation circuit electrically coupled to the correction circuit and configured to deliver an additional voltage to the correction circuit to modify a setpoint voltage when the input voltage falls below a predetermined value.
