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

Fluorescent lighting fixtures: fluorescent ballasts and starter. Each of the two ends of the lamp a filament, a tube filled with a dilute book argon and trace amounts of mercury vapor, and coated with phosphor on the tube wall. The gas between the two filaments of the conductive when mainly emits ultraviolet light, the phosphor emits visible light by ultraviolet irradiation. Gas conductivity have a characteristic: only when the voltage across the lamp reaches the value of the higher voltage (220V voltage) is greater than the power provided by the gas can be conductive; normal work to maintain a certain size of the current in the lamp vessel, the required the voltage is small (less than the power supply voltage of 220V). Therefore, if the voltage of 220V is directly added to the ends of the lamp does not transform the lamp ignited. With magnetic ballast and starter will be able to solve this problem.
