Research on the energy-saving efficiency and economy of ballast

This paper has given qualitative and quantitative analysis and comparisons to the following 4 types of ballasts, the traditional inductance-ballast, high-quality electronic ballast, low-quality electronic ballast and energy-saving inductance-ballast. It has also demonstrated that the electronic ballast may save electricity but not money, while the energy-saving inductance-ballast possesses excellent energy-saving and economy efficiencies. All these have supplied a helpful reference for the manufacturers in producing and users in correctly choosing the ballast.
