Manufactured by Fuzhou Dongshi Lighting, a company with over two decades of experience in the lighting industry, this luminaire combines energy efficiency with robust construction. It is designed to replace traditional high-pressure sodium (HPS) or metal halide (MH) lamps, offering superior illumination, longer lifespan, and significant energy savings. The light features an adjustable light distribution pattern (Type II, Type III, Type V) and is built to withstand harsh environmental conditions, making it suitable for highways, parking lots, gardens, and public squares.

Key Technical Specifications

Product Usage & Applications

This versatile LED street light is designed for a wide range of outdoor lighting scenarios, providing safe and efficient illumination.

• Municipal Roads & Highways: Ideal for illuminating residential streets, arterial roads, and highway interchanges due to its adjustable light distribution and high luminous efficacy.
• Parking Lots & Car Parks: Provides bright, uniform light for enhanced security and visibility in commercial, industrial, and retail parking areas.
• Public Areas & Gardens: Used in parks, squares, and pedestrian pathways to create a safe and pleasant nighttime environment.
• Industrial & Security Lighting: Suitable for perimeter lighting of factories, warehouses, and other facilities requiring high levels of security and reliability.

Installation & Maintenance Guide

Installation

Installation should be performed by a qualified electrician in accordance with local electrical codes. The process typically involves:

1. Mounting: The luminaire is typically mounted on a pole using a bracket. Ensure the pole is structurally sound and of appropriate height (usually 6-10 meters for 50W).
2. Wiring: Connect the input wires (Live, Neutral, Ground) from the power supply to the corresponding terminals in the luminaire's driver compartment. For dimmable versions, connect the dimming control wires as per the wiring diagram provided.
3. Orientation: Adjust the angle and orientation of the lamp head to achieve the desired lighting coverage on the ground.

Maintenance

LED street lights require minimal maintenance. However, periodic checks are recommended:

• Cleaning: Clean the glass/PC cover periodically to remove dust, dirt, and bird droppings that can reduce light output.
• Inspection: Visually inspect the fixture for any physical damage, water ingress, or signs of corrosion, especially after severe weather events.
• Performance Check: Monitor the light output over time. A significant drop in brightness may indicate driver or LED module issues.

Purchasing Guide & Supplier Information

When purchasing 50W LED street lights, consider the following factors to ensure you get a quality product that meets your project's requirements.

Supplier Profile: Fuzhou Dongshi Lighting Technology Co., Ltd.

• Location: Fuzhou, Fujian, China.
• Business Type: Custom Manufacturer, Supplier, and Trading Company.
• Experience: Over 21 years in the lighting manufacturing industry.
• Capabilities: Offers OEM and ODM services, providing product customization based on client specifications.

Key Purchasing Considerations

• Verify Certifications: Ensure the product has relevant safety and performance certifications (ETL, CE) for your target market.
• Request LM-80 Data: Ask the supplier for the LM-80 test report of the LEDs used. This report provides data on lumen depreciation and is crucial for verifying the claimed lifespan.
• Check Warranty Terms: Understand the warranty coverage. A 5-year warranty is standard for quality products, but confirm what it covers (parts, labor, lumen maintenance).
• Compare Photometric Data: Look beyond wattage and compare lumens, efficacy (lm/W), and light distribution patterns (IES files) to ensure the light meets the specific requirements of your project.
• Request Samples: Before placing a large order, request a sample to evaluate the build quality, light color, and performance firsthand.

Product Evaluation & Testing Standards

Professional evaluation of LED street lights is based on a set of international standards that measure performance, safety, and longevity.

• Safety Standards: UL/cUL, ENEC, and other regional standards ensure the product is electrically safe.
• Performance Testing (IES LM-79): This standard covers the electrical and photometric testing of LED products, measuring lumens, efficacy, color temperature (CCT), and color rendering index (CRI).
• Lumen Maintenance (IES TM-21): This is a calculation method used to project the long-term lumen maintenance of LEDs based on LM-80 test data. It is the industry standard for predicting lifespan (e.g., L70 at 100,000 hours).
• Ingress Protection (IP Code): IP66 rating confirms the fixture is dust-tight and can withstand heavy rain, making it suitable for outdoor use.
• DLC Certification: In North America, the DesignLights Consortium (DLC) qualification is often required for utility rebates and incentives. It sets higher bars for efficacy and performance.

After-Sales Service & Support

Reputable suppliers offer comprehensive after-sales support to ensure customer satisfaction.

• Warranty Service: A 5-year warranty typically covers defects in materials and workmanship. The supplier should provide a clear process for warranty claims and replacements.
• Technical Support: Suppliers should offer technical support to assist with installation, wiring, and troubleshooting.
• Spare Parts Availability:
               
• Return & Refund Policy: Understand the terms for returning defective or non-conforming goods.
