What aspects need to be considered when choosing streetlights?
When purchasing street lights, several technical and environmental factors must be evaluated to ensure long-term performance and efficiency. Based 
on ZENOME's technical documentation and project experience, here are the key aspects to consider:
1. Power Supply and Application Scenario
Grid-Powered vs. Solar-Powered: Choose grid-connected lights for areas with reliable infrastructure and stable power needs. Solar street lights are ideal for remote locations, parks, and residential roads where eliminating wiring and electricity costs is a priority.
Hybrid Solutions: In regions with inconsistent sunlight, AC/DC Hybrid solutions can automatically switch between solar and grid power to ensure 365-day operation.
2. Matching Pole Height and Lamp Power
It is critical to match the recommended lighting power with the specific height of the light poles to achieve the required illuminance level.
Standard Poles (6m–10m): Typically used for urban roadways and residential streets.
High Mast (20m–30m+): Specialized for large areas like stadiums, squares, and industrial zones, sometimes requiring outputs as high as 240,000 lumens.
Wattage Range: ZENOME provides models ranging from 20W up to 500W to suit various roadway widths and visibility requirements.
3. Solar System Components (For Solar Models)
Solar Panels: Prioritize Monocrystalline silicon panels for their higher conversion efficiency (often 23.5% to 25%) and better performance in low-light conditions.
Battery Type: High-quality systems use LiFePO4 (Lithium Iron Phosphate) batteries because they are safer and more durable than lead-acid or ternary lithium options, often delivering a lifespan of over 60,000 hours.
Controllers: Look for intelligent controllers (like MPPT) that optimize charging and manage lighting modes.
4. Durability and Material Quality
Poles: Poles should be constructed from hot-dip galvanized steel to ensure corrosion resistance for 20+ years. They must also be designed to meet local wind load requirements, such as resisting wind speeds of 150km/h to 200km/h.
Ingress Protection (IP Rating): Outdoor fixtures must have a high waterproof and dustproof rating, typically IP65 to IP68, to withstand harsh weather and monsoons.
Operating Temperature: Ensure the components (especially batteries and LEDs) can operate reliably in your local climate, with some industrial-grade lamp heads rated for -40°C to 60°C.
5. Smart Control and Energy Efficiency
Intelligent Modes: Modern systems offer Dusk-to-Dawn automation and motion sensors (PIR or microwave) that dim the light when no movement is detected, which can reduce energy costs by up to 60%.
IoT Integration: For smart city projects, consider systems that support Zigbee or Bluetooth protocols for remote monitoring and group management via mobile apps.
6. International Certifications
To guarantee quality and safety standards, ensure the products carry recognized certifications such as CE, RoHS, ISO 9001, FCC, TUV, or SAA.
