Energy-saving lamps, also known as energy-saving light bulbs, electronic light bulbs, compact fluorescent lamps, and integrated fluorescent lamps, refer to lighting devices that combine fluorescent lamps and ballasts (ballasts) into a single unit. In 2008, the state launched the "Green Lighting" project. Urban and rural residents and enterprises use the energy-saving lamps of the winning bidder to enjoy a certain percentage of subsidies. The promotion of energy-saving lamps is of great significance. However, the environmental hazards of used energy-saving lamps have also attracted attention. By the end of October 2012, hundreds of millions of energy-saving lamps were scrapped for energy-saving promotion projects, each of which could pollute 180 tons of water and 56 acres of soil. Attention has been paid to the disposal and recycling of used energy-saving lamps. Despite this, people's demand for energy-saving lamps is still growing, especially in the coming 2015, demand is still increasing.
