Advantages Compared to the Street Light:
1. Long lifespan: LED street lamp can be used for more than 50000 hours.
2. High light efficiency: using ≥100LM chip, saving more than 75% energy than the traditional high pressure sodium lamp.
3. Low photo degradation (decline to 3% a year); meet the road illumination requirements after10 years, while high pressure sodium lighting’s photo degradation is high (more than 30% a year). Therefore, LED street light’s working power design can be lower than high pressure sodium lamp.
4. Unique twice optical design, let the light irradiate the lighting desired areas; further improve the efficiency of light, in order to achieve the purpose of saving energy.
5. Characteristics – unidirectional light, without light diffusion, guarantee of light efficiency.
6. Automatic control energy saving device, can meet the needs of illumination in different time, saving electric energy.
7. Reliable quality: the circuit of power supply is made of high quality components, with over current protection.
8. Easy installation: without buried cable and rectifiers, directly replace the original street lamp.
