Abstract
A low pressure gas discharge lamp ballast circuit is provided for three series-connected low energy gas discharge lamps, in which a first starting capacitor provides a starting voltage to one of the lamps, and a second starting capacitor provides a starting voltage to a second one of the lamps in sequence, so that the ballast losses can be minimized by reducing the ratio of the voltage applied across the three lamp system to the total lamp voltage, while still maintaining the light output and not having to use expensive lamp bases and lampholders.
