LED Traffic Light Buying Guide: 10 Factors to Consider
Choosing the right LED traffic light is critical for road safety and project success. This guide covers the 10 most important factors buyers should evaluate before making a purchase.
1. LED Diameter and Visibility Distance
Common sizes include 100mm, 200mm, 300mm, and 400mm. Larger diameters provide longer visibility distances and are ideal for highways and wide intersections.
2. Number of Aspects
Traffic lights come in 1, 2, 3, or 4 aspect configurations. Choose based on the number of signal phases required for your intersection.
3. Input Voltage
Standard options include AC 85-265V and DC 12V/24V. Solar-powered systems typically use low-voltage DC options.
4. Certification Standards
Look for EN12368, CE, RoHS, and IP65 certifications to ensure quality and compliance with local regulations.
5. Housing Material
Polycarbonate (PC) and aluminum are common materials. PC offers impact resistance, while aluminum provides better heat dissipation.
6. Operating Temperature Range
Ensure the traffic light can operate in your local climate, especially in extreme heat or cold environments.
7. Protection Rating (IP Rating)
IP65 or higher is recommended for outdoor traffic lights to protect against dust and water.
8. Control Compatibility
Verify compatibility with your existing traffic signal controller or choose a complete system from one supplier.
9. Customization and OEM Support
If you need branded products or custom specifications, confirm the manufacturer offers OEM/ODM services.
10. Manufacturer Experience and Support
Choose a manufacturer with proven experience, quality control, and after-sales support. GAOQIAO has 17+ years of experience in LED traffic light manufacturing.
Conclusion
By considering these 10 factors, you can select LED traffic lights that meet your project requirements, comply with local standards, and provide long-term reliability.
