Hubei Province Energy Saving Service Company and State Grid Xiangyang Power Supply Company will plan to renovate 5513 ç¯å…· lamps in 6 counties and cities in Xiangyang, and change the original sodium lamp to LED lamp. The power consumption will be reduced by 60% year-on-year, and the annual energy saving will be 25.1 million. Kilowatt hours is equivalent to saving 1190 tons of standard coal. After the renovation of the street lamp, the service life has been increased from the previous 8,000 hours to 50,000 hours, which further reduces the safety risk of manual maintenance.
