Energy-saving lamps, also known as provincial electric light bulbs, electronic bulbs, compact fluorescent lamps and one-piece fluorescent lamps, refers to the combination of fluorescent lamps and ballast (ballast) into a whole lighting equipment. In 2008, the "green lighting" project was launched in the country, and the urban and rural residents and enterprises enjoyed a certain proportion of subsidies in the use of the china-standard enterprise energy-saving lamps. The promotion of energy-saving lamps is significant. However, the environmental hazards of waste energy saving lamps have also attracted attention. By the end of October, 2012, hundreds of millions of energy-saving projects have been scrapped. Each can pollute up to 180 tons of water and five or six mu of soil, and the treatment and recycling of waste energy-saving lamps has attracted attention. Still, demand for energy-saving lamps continues to grow, especially in 2015, when demand is still increasing.
