3. LED has reached 110-130lm/W, and there is still a lot of room for development, and the luminous efficiency of high-pressure sodium lamps increases with the increase of power. Therefore, the overall luminous efficiency of LED tooless street lamps is stronger than that of high-pressure sodium lamps; (this The overall luminous efficiency is theoretical, in fact, the luminous efficiency of high-pressure sodium lamps above 250W is higher than that of LED lamps);
5. The light decay is small, less than 3% in one year, and it still meets the road requirements after 10 years of use, while the high-pressure sodium light has a large decay, which has dropped by more than 30% in about a year. Therefore, LED tooless street lights are designed in terms of power usage. Can be lower than high pressure sodium lamps;
9. Easy installation: no need to bury cables, no rectifiers, etc., directly connect to the lamp pole or nest the light source into the original lamp shell;
13. LED does not contain harmful metal mercury, which will not cause harm to the environment when it is scrapped.
