What is a pulse-start metal halide ballast?
The term “pulse-start metal halide ballast” means an electronic or electromagnetic metal halide ballast that starts a pulse-start metal halide lamp with high voltage pulses. Lamps shall be started by first providing a high voltage pulse for ionization of the gas to produce a glow discharge, and to complete the starting process, power shall be provided by the ballast to sustain the discharge through the glow-to-arc transition.
