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

Compact fluorescent lamps by the capacitor, an electronic ballast, a relay, a starter, lamps and other components. The model instead of using two capacitors or RC fluorescent ballast, and in the glow starter circuit in series with a relay, changeover contact relay turned on or off to change the two coupling capacitors, capacitance to change to accommodate a fluorescent lamp starting and lighting different currents required. Starting and therefore fluorescent lighting are in top working condition. When the lamp is illuminated when the circuit (except for the outer tube) there is almost no energy components, with the best energy-saving effect.
