The power supply is electrically coupled to the arc lamp and configured to provide power thereto, and the power control servo is coupled to the power supply, and configured to cause the power supply to provide lower power to the arc lamp at a beginning of the life span, and to provide greater power to the arc lamp toward an end of the life span.
