How to Upgrade Post Top Lights by Replacing Mercury Lamp with LED HID Bulbs?

Hello, Everyone! today I’d like to share an exciting and practical application of our WYX series LED HID bulbs. These bulbs are a game-changer for upgrading traditional post top lights and garden lights, offering unparalleled efficiency and sustainability.

Let’s explore how these LED bulbs outperform traditional mercury lamp and why they are the perfect solution for modernizing your outdoor lighting setup.

The Classic Post Top Light

Post top lights, also known as garden lights, are iconic outdoor lighting fixtures commonly found in parks, squares, yards, and along pathways. Their elegant designs not only enhance the aesthetics of public and private spaces but also provide functional illumination for safety and ambiance.

For decades, many of these lights have relied on mercury lamp (ML) for their light source. The ML 250W or ML 500W bulbs were popular choices because of their affordability and availability. However, as lighting technology has advanced, the shortcomings of mercury lamps have become evident.

Drawbacks of Mercury Lamp in Post Top Lights

While mercury lamps were once considered cutting-edge, they now fall short in multiple ways:

Short Lifespan
- Mercury lamp typically last only about 10,000 hours. For fixtures installed at heights, such as post top lights, frequent bulb replacement leads to high maintenance costs and inconveniences.
Environmental Impact
- Mercury lamp contain mercury, a toxic substance that poses significant environmental and health risks when not disposed of properly.
- Recognizing this hazard, the European Union has announced a ban on importing and using mercury-containing products, effective December 31, 2025.
Low Energy Efficiency
- With an efficiency of just 20 lumens per watt (lm/W), mercury lamp consume substantial energy, contributing to higher electricity bills.
Poor Color Rendering
- Mercury lamp have a color rendering index (CRI) of only 60, resulting in poor visibility and unnatural lighting.
Energy Waste
- The inefficiency of mercury lamp leads to significant energy waste, making them an unsustainable option in today’s eco-conscious world.

Step-by-Step Replacement Guide for Post Top Lights

If you’re ready to upgrade your post top lights and garden lights, here’s how you can easily replace your old mercury lamp with our WYX series LED HID bulbs:

Step 1: Determine the Right LED Bulb

Refer to our replacement chart to select the appropriate LED bulb for your fixture:

For an ML 250W mercury lamp, choose our 35W WYX LED HID bulb.
For an ML 500W mercury lamp, select our 80W WYX LED HID bulb.

The WYX bulbs are designed to match the size and socket type (E27 or E40) of traditional mercury lamp, ensuring a perfect fit.

Step 2: Remove the Ballast

Our WYX LED HID bulbs feature an integrated AC 90-277V driver with 6kV surge protection. This eliminates the need for an external ballast, which is often found in fixtures designed for mercury lamp. Before installation:

Safely disconnect the power supply.
Open the fixture and remove the existing ballast.

Step 3: Install the LED Bulb

Once the ballast is removed:

Screw the WYX LED bulb directly into the E27 or E40 socket.
Ensure the bulb is securely in place.

Step 4: Verify Heat Dissipation

Since post top lights and garden lights are typically enclosed fixtures, proper heat management is crucial. Our WYX series bulbs are equipped with an active cooling fan (manufactured by SUNON), which efficiently dissipates heat to ensure optimal performance and longevity.

Step 5: Test the Fixture

Reconnect the power supply and test the fixture to confirm proper installation. You’ll immediately notice the enhanced brightness and improved light quality.
