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

High pressure sodium ballasts for HID gas discharge lamp inductively ballast. HID is High intensity Discharge high-pressure gas discharge lamp abbreviation, mercury, sodium, gold, xenon lamp, collectively, mercury lamps, sodium lamps, metal halide lamps, xenon lamp. The inductive ballast is an iron core inductor coil, the nature of the inductor when the current in the coil is changed, the change of the magnetic flux in the coil will cause, thereby generating an induced electromotive force, direction and current of the opposite direction, thereby preventing forward metal halide ballasts current changes.
