China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

Ballasts are devices required for the operation of gas lamps (including fluorescent lamps, metal halide lamps, and high pressure sodium lamps). Ballasts provide the initial starting voltage to a gas lamp. The initial starting voltage provided by the ballasts creates an electrical arc that excites the gases in the lamp, thus producing light. Because ballasts are essential to fluorescent lamp operation, they have been available for as long as the lamps they start and regulate. Throughout most of their history, fluorescent ballasts have been electromagnetic. As a result of their design, these ballasts are also called “core ballasts".
