Abstract
A starting system for an electrodeless metal halide discharge lamp includes a parallel tuned LC network including a fixed capacitor and a starting inductor, and also including a conductive plate for application to the starting inductor for detuning the network once the lamp has started. The detuned starting network produces insufficient voltage to maintain the starting plasma while the lamp is running. The conductive plate is removed from the starting inductor by a solenoid or other mechanical actuator during lamp starting.
