FAQ

1. How to choose wattage for street light?

It mainly depends on road width, pole height, pole spacing, required luminance and local road lighting standard. For reference: 30–50W for rural roads & narrow lanes; 80–120W for secondary roads; 150–200W for main arterial roads. Send us your road conditions, we can recommend the optimal wattage with DIALux simulation.

2. What beam type do I need for my road?

Type II for narrow road, one-side mounting. Type III is the most common for two-lane roads. Type IV suits wide roads, parking lots and industrial zones. Type V is for squares and open areas. We will confirm the best optical distribution based on your layout.

3. Can you support DALI / NEMA smart control?

Yes. Our LED street lights support DALI, DALI-2, 0-10V dimming, NEMA 7-pin/Zhaga socket, and GSM intelligent control system. Smart functions include dimming, timing, remote monitoring and fault alarm. Custom control solutions are available.

4. Do you provide DIALux simulation report?

Yes, free DIALux lighting simulation service for project customers. Please share your road drawing, pole height, spacing and lighting requirements, our optical team will deliver the simulation report with luminance, uniformity and glare data.

5. What certificates are available for tender project?

We have ENEC+, ENEC, CB, CE, ETL, IP66 test report, IK09/IK10 impact test report and other required documents. We can supply full tender documentation including test reports, manufacturer authorization and product datasheets upon request.

6. How often do LED street lights need to be replaced?

LED street lights feature an ultra-long service life. With high-quality drivers and chips, our fixtures reach 50,000–100,000 hours of rated lifespan. Under normal road operating conditions, this equals approximately 10–20 years of service.

Note: This refers to the rated lumen maintenance life. Individual components such as drivers may require inspection or replacement during the service period. Proper routine maintenance can further stabilize performance and extend working life.
