Meeting high market demands and keeping "green lighting" in mind, Anrui has developed the 1000W electronic ballast with 120-240V wide input voltage range, and lights both Metal Halide lamp and High Pressure Sodium lamp.Anrui is one of the few successful companies able to produce such a product, while others have failed due to the complications that are encountered with high wattage electronic ballasts.Anrui is still able to keep the important energy-saving feature, as well as high power factor >0.99, and low total harmonic factor <10%. We focus on quality and also have pricing into consideration.
