Upgrading Street Lamps: Replacing 400w high pressure sodium with Efficient LED Solutions

today I want to share an inspiring case study about how we successfully retrofitted a classic street lamp with modern LED lighting. This project not only demonstrates how LED technology can significantly improve performance but also highlights the cost-effectiveness and sustainability of such upgrades.

The Challenge: Classic Street Lamps with 400W high pressure sodium

The street lamp in question is a well-recognized design with over 30 years of application history. This iconic fixture is widely used on city main roads and is commonly seen across Europe, Asia, Australia, South America, and many other regions. Its timeless design integrates beautifully with urban landscapes and is built to last over 20 years.

However, the original 400W high pressure sodium inside the lamp presented several challenges:

• High Maintenance Costs: The client had to replace the HID bulb every few months due to its short lifespan. This frequent maintenance led to excessive labor costs.
• High Energy Consumption: The 400W HID consumed significant amounts of electricity, leading to unsustainably high power bills.
• Environmental Impact: High energy use and frequent replacements generated unnecessary waste, making the setup less eco-friendly.

The client wanted a solution that could retain the aesthetic and durable housing of the streetlamp while providing modern performance benefits such as improved efficiency, reduced costs, and a lower carbon footprint.

The Retrofit Solution: led corn lamp

At ANTSLIT, we specialize in LED HID retrofit solutions designed to upgrade traditional HID fixtures with energy-efficient LED lighting while maintaining their original form. For this project, we identified the ideal solution: replacing the 400W HID bulb with our advanced 175W led corn lamp.

Why Retrofit LED Lighting?

• Energy Efficiency: led corn lamp consume significantly less energy than HID bulbs, providing up to 60% energy savings.
• Reduced Maintenance: led corn lamp have a much longer lifespan, drastically reducing the need for replacements and associated labor costs.
• Cost-Effectiveness: The combination of energy savings and reduced maintenance costs can result in up to 200% cost reduction over time.
• Eco-Friendly: LEDs produce less waste and consume less electricity, reducing the environmental impact.

The Three-Step Retrofit Process

Step 1: Choosing the Right LED Bulb

Our team identified that the 175W led corn lamp was the perfect replacement for the original 400W HID bulb. This led corn lamp not only matched the brightness output of the HID (30,000 lumens) but also had a similar size, ensuring compatibility with the existing fixture.

Step 2: Removing the Ballast

HID systems typically rely on a ballast to regulate current. However, our LED bulbs come with an integrated LED driver that supports AC90-277V input and includes 6kV surge protection. This integration eliminates the need for the ballast, simplifying the setup and reducing potential failure points.

To prepare for the retrofit:

1. The old ballast inside the streetlamp was safely removed.
2. The wiring was adjusted to allow direct connection to the led corn lamp.

Step 3: Installing the led corn lamp

Finally, we installed the 175W led corn lamp into the existing housing. The process was straightforward, requiring no significant modifications to the fixture. The result was a seamless upgrade that preserved the lamp’s classic appearance while delivering modern lighting performance.

The Results: LED Performance and Benefits

The upgraded street lamp now boasts the following advantages:

1. Improved Energy Efficiency

The led corn lamp uses only 175W, compared to the original 400W high pressure sodium, resulting in a 56% reduction in energy consumption. This translates to significant savings on electricity bills.

2. Lower Maintenance Costs

LEDs have an average lifespan of 50,000 hours, far surpassing the lifespan of HID bulbs, which typically last only a few months. This reduces the frequency of replacements, cutting labor and maintenance costs by up to 200%.

3. Enhanced Durability

The LED bulb’s robust design, including 6kV surge protection, ensures reliable performance even in challenging electrical environments.

4. Sustainability

Switching to LEDs reduces waste generated by frequent HID replacements and lowers carbon emissions due to decreased power consumption.

Common Scenarios for HID to LED Retrofits

This case study is just one example of how LED technology can transform outdated lighting systems. Here are other typical HID to LED retrofit scenarios:

1. 400W High-Pressure Sodium LED Replacement

Upgrading 400W High-Pressure Sodium bulbs to LED equivalents is common in street lighting, parking lots, and stadiums. LEDs deliver the same brightness with far less energy and longer lifespans.

2. metal halide LED Replacement

metal halide lamps, often used in outdoor settings, can also be replaced with LED corn bulbs to improve color rendering and energy efficiency.

3. Mercury Vapor LED Conversion

Replacing mercury vapor bulbs with LEDs eliminates hazardous materials while providing better lighting quality and efficiency.
