After replacing the 4 lights in the airport building of the Capital Airport with new LED energy-saving high-pole lights, they can save more than 50% of the electricity compared to the previous high-pressure sodium lights, and can save 19,000 kWh a year. This is the city's first trial of a new type of LED energy-saving lamps in public buildings. Yesterday, at the appraisal meeting of the latest technological achievements of high-brightness LED lighting, the new energy-saving lamps have been tested for more than half a year and proved that the energy-saving rate is between 50% and 70%.
