Outdoor light fixtures with glass panels or covers can accumulate dirt, grime, and mineral deposits over time. While regular cleaning can help, sometimes the glass becomes so coated or deteriorated that it needs to be fully removed and replaced. Removing the glass from an outdoor light fixture is usually a straightforward process, but care should be taken to avoid breakage or injury. Follow these steps to safely remove the glass from your outdoor lighting.
Gather Necessary Materials
Before removing the glass, make sure you have all the supplies you’ll need readily available:
- Safety glasses
- Work gloves
- Screwdriver (flathead and/or Phillips)
- Needle nose pliers
- Replacement glass (if needed)
Safety is paramount when working with glass. Be sure to wear gloves and eye protection at all times to avoid cuts from broken shards. Have all tools on hand before beginning disassembly. Measure the existing glass panels and purchase replacements ahead of time if the glass is broken or too cloudy/deteriorated to clean.
Turn Off Power Supply
The light fixture must be completely deactivated and disconnected before attempting glass removal. Locate the circuit breaker or fuse powering the outdoor light and turn it off. If you are unsure which breaker/fuse to switch off, turn off the main power to be safe.
With the power supply disabled, use a non-contact voltage tester on the light fixture wires to confirm they are no longer live. Test multiple points, including the fixture mounting, frame, and lamp wires. Do NOT proceed until you verify there is zero voltage present.
Remove Exterior Fixture Housing
With the power off, use a screwdriver to detach any screws or brackets holding the main fixture housing in place. This may require unscrewing the mounting plate from the electrical box first. Carefully separate the housing from the wall or ceiling to access the interior.
Set the fixture housing safely aside on a flat, stable surface. Be careful not to put excessive strain on any interior wiring still attached.
Release Securing Clips or Frames
The glass panes or panels should now be visible. Look for any plastic or metal clips, tension rings, or frames holding the glass in place and carefully remove them. This usually just involves loosening screws or unclipping tabs.
On round fixtures, there is often a decorative metal piece called a gallery holding the glass. Remove any fasteners to detach the gallery frame. Release one section at a time if dealing with a multi-paneled frame.
Extract the Glass Panels
With all clips, tension rings, and frames removed, the glass should be loose. Wearing thick gloves, grip the panel firmly and pull it straight out from the fixture. Tilting the glass slightly may help release it. Take care not to put any torque on the glass to avoid cracking it.
Extract any remaining glass panels or pieces in the same manner. Collect all the hardware pieces (clips, screws, etc) and set them aside with the housing. Examine for any cracked, broken, or missing components.
Clean Surfaces and Install New Glass
With the old glass fully out, take the opportunity to clean the fixture interior and any remaining glass panels. Use mild soap and water with a soft cloth to remove dirt and buildup. Check for any deterioration in the gaskets or seals.
Once dry, insert any new replacement glass according to the original design. Reinstall any frames, retention clips, or tension rings in the proper order and orientation. Tighten screws just until the glass is firmly flush, but not overtightened.
Reassemble the Light Fixture
With the glass securely back in place, reattach the outer fixture housing. Align any screw holes and firmly refasten using a screwdriver. Ensure no wires are pinched or crushed in the process.
If you detached a mounting plate, return it to its original position and screw it back onto the electrical box. Double check that all fasteners are tightened properly so the light remains secure.
Restore Power and Test
With everything reassembled correctly, return power to the fixture by turning the breaker or fuse back on. Use a voltage tester to verify electricity is running to the light.
Carefully switch the light on and visually inspect from all angles that the new or cleaned glass is properly fitted. Check that all internal components, gaskets, and seals appear intact. The fixture should now give off an even glow without issues.
Safety Tips
When removing and replacing the glass components in outdoor lighting, keep these additional safety guidelines in mind:
- Put a tarp below the fixture to catch broken glass or parts.
- Only work during daylight hours with good visibility.
- Avoid touching the light bulb to prevent burns.
- Make sure hands are clean and dry when handling electrical connections.
- Do not operate the light if the housing cannot close fully or if there is exposed wiring.
- Ensure water drainage holes are not obstructed to prevent moisture buildup.
- Wear safety glasses and gloves to protect from sharp edges and electricity.
- Inspect fixtures regularly and replace deteriorated gaskets, seals, silicone, etc.
Observing prudent precautions is the key to removing glass from outdoor lights safely. With the proper tools and careful handling, this upgrade can extend the longevity of exterior lighting and maintain optimal illumination.
Frequently Asked Questions
How can I tell if the outdoor light glass needs to be replaced?
Signs that the glass panels or covers in your outdoor light fixtures need replacement include:
- Visible cracks, chips, or holes
- Cloudy, foggy, or frosted appearance
- Dirt and debris that cannot be removed by cleaning
- Leaking when it rains
- Bulb light appears uneven or obscured
If the glass is so deteriorated that it significantly reduces the light output, then replacement is likely needed.
What special tools do I need to remove outdoor light glass?
You’ll need very few speciality tools. The most important are safety glasses, work gloves, a voltage tester, plus basic hand tools like screwdrivers, pliers, and putty knives. A stepladder, tarp, and replacement glass may also be required. Avoid using power tools which could easily shatter the glass.
What kind of glass should I use to replace outdoor light covers?
Look for glass specifically designed for outdoor fixtures. Tempered glass is best since it is stronger and more shatter-resistant. Select UV-resistant glass to prevent clouding over time. Glass thickness should match the original – usually around 0.25 inches. Any local hardware store carries glass panels made to fit standard fixture sizes and shapes.
What should I do if the glass breaks as I’m trying to remove it?
Turn off the power immediately if you accidentally crack or shatter the glass. Carefully sweep up all shards using a brush and dustpan. Wear leather gloves and eye protection. Vacuum the fixture interior before installing new glass. Broken tempered glass can shatter into many small pieces so be sure to remove them all.
Can I just remove the glass instead of replacing it?
While the glass can technically be left off, this is not advisable for most outdoor fixtures. The glass shields the lamp and reflective surfaces from weather damage. It also prevents moisture, dirt, and insects from getting inside. Lack of glass may impact the light performance. Only leave it off temporarily while replacement glass is being acquired.
How often should I plan to replace outdoor light glass?
With proper maintenance, quality glass panels should last 3-5 years in outdoor fixtures. Regular cleaning helps prolong its lifespan. Eventually though, the glass becomes irreversibly foggy or cracked and needs replacement. Inspect fixtures seasonally and replace glass as soon as issues appear to maintain optimal illumination.
Conclusion
Removing and replacing the glass in outdoor light fixtures is an important maintenance task to improve illumination and protect internal components. With some common tools and proper precautions, DIYers can safely handle this upgrade project. Inspect fixtures regularly to determine if the glass needs replacement. When cracked, broken, or excessively clouded, follow the steps above to remove the existing glass and install new panels. Take care when working at heights and handling broken shards. With patience and care, you can keep your outdoor lighting glowing like new for years to come.
