Abstract
A fluorescent lamp starter circuit that incorporates the series arrangement of a glow-switch and a semiconductor switch. The semiconductor switch is coupled to a solid state timer. The solid state timer renders the semiconductor switch non-conductive after it has timed a predetermined maximum operation interval. The duration of lamp ignition attempts is thereby limited.
