7. Long life: can use more than 50000 hours, provide three years of quality assurance, the disadvantage is that the life of the power supply can not be guaranteed;
8. High luminous efficiency: the chip with more than 100 LM can save more than 75% energy compared with the traditional high pressure sodium lamp;
9. Simple installation: no need to bury the cable, no need to rectifier, etc., directly installed on the lamp pole or the light source nested in the original lamp shell;
10. Excellent cooling control: in summer, the temperature is controlled below 45 degrees, and the passive cooling mode is adopted, so the cooling guarantee in summer is insufficient;
11. Reliable quality: circuit power supply adopts high quality components, each LED has a separate over-current protection, no need to worry about damage;
12. Uniform light color: without lens, uniform light color is not sacrificed to improve brightness, so as to ensure uniform light color without aperture;
13. LED does not contain harmful metal mercury and will not cause harm to the environment when it is scrapped.
