Abstract
A starter circuit for metal halide discharge lamps in which a diode resistor rectifier network is provided between a conventional ballast and a spiral line generator to superimpose a D.C. voltage on the A.C. ballast voltage thereby to increase the peak instantaneous voltage to the spiral line generators and thus provide a larger breakdown voltage to the discharge lamp.
