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

Magnetic ballast is the original type of ballast for a metal halide bulb, and for many years was the only option available. It remains the most common type, in part because it’s much cheaper to buy than electronic ballast. Depending on the wattage of bulb you’ll power with the magnetic ballast, expect at least a loss that will be around 10 percent of the lamp wattage, and can be much higher. You can buy magnetic ballast for metal halide lamps of up to 1500 watts.

Fluorescent and HID lamps require a core and coil ballast to apply starting voltage to the lamp and establish current flow – an "arc" – between the lamp electrodes. Once the lamp is operating, the ballast also regulates lamp current and power.Ballasts, particularly for fluorescent systems, can be further categorized by their lamp starting and operating method. Starting and operating methods now available are balanced between lamp life, energy consumption and overall system costs that allow the user to select the system best suited for their application.
