ABSTRACT OF THE DISCLOSURE Circuit operating from a direct current source applies DC pulses to a high pressure sodium vapor lamp to improve the color properties of the lamp. The circuit includes a controlled thyris- tor switch in series with the lamp, an RC timing circuit for periodically turning on the switch at predetermined intervals, and an LC circuit for turning the switch off. An inductor comprising the primary winding of a transformer in series with a diode across the capacitor of the LC circuit provides for discharge of the capacitor to enable subsequent re-charging thereof, so as to produce the desired pulsed operation of the circuit, and the trans- former secondary winding in series with a diode clamps the voltage of the primary winding. The disclosed arrangement prevents exces- sive voltage across the controlled switch and provides for the control of lamp wattage with respect to changes in lamp voltage.
