Light globes are easy to forget in a regular cleaning routine—but over time, they collect dust, bugs and grime that can reduce their brightness and efficiency. Cleaning your globes is a quick and simple task that can help extend their lifespan and improve the look and feel of your home.
Just like any electrical task, safety comes first. Whether you’re dealing with ceiling-mounted lights, track or rail systems or fluorescent fittings, it’s important to approach the job with the right tools and steps.
Why clean your light globes?
A dusty or dirty globe can emit noticeably less light than a clean one. In some cases, up to 30% of brightness can be lost. That affects not only how a room looks, but how well-lit it feels for reading, cooking or working.
Clean globes also run cooler, which is especially important for halogen or incandescent types. While LEDs are far more efficient and run at lower temperatures, they still benefit from occasional cleaning to keep performance consistent.
Keeping your lights clean is also one of the easiest ways to reduce the running costs of your lighting, especially when combined with smart switching options like motion sensors or energy management systems.
Safety first: always switch off the power
Before you clean any light fitting, turn it off at the wall and let the globe cool completely. If the globe is part of a ceiling light or downlight, it’s best to turn off the power at the switchboard as well. Never attempt to clean a warm or live fitting—it’s not worth the risk.
Use a stable ladder or step stool for ceiling lights and ensure the area around you is clear. If you’re unsure about removing a globe safely or accessing a high or complex fitting, consult a licensed electrician.
How to clean different types of globes
Standard glass globes (LED, halogen or incandescent)
Remove the globe from the fitting once it has completely cooled. Use a soft, dry microfibre cloth to gently wipe away dust and smudges. For more stubborn grime, lightly dampen the cloth with water and a drop of mild detergent—then dry the globe thoroughly before replacing it.
Frosted or decorative globes
Treat frosted finishes gently, as abrasive cleaners can damage the surface. Use a dry or barely damp cloth and avoid scrubbing. If your fitting includes glass or plastic shades, clean those separately using a soft cloth and mild cleaning solution.
Compact fluorescent globes (CFLs)
Be especially careful with CFLs, as they contain a small amount of mercury. If you need to remove one for cleaning, avoid knocking or dropping it. Dust gently with a dry cloth. If a CFL breaks, follow proper disposal guidelines and ventilate the area immediately.
Integrated LED fittings
Some modern fittings don’t have removable globes. In this case, simply dust the fitting and diffuser surface with a dry cloth or soft brush. Avoid using water or cleaning sprays directly on the unit, as this can damage internal components.

When to clean your globes
There’s no hard rule, but most homes will benefit from cleaning their lights every 3 to 6 months. You may need to clean them more often in high-use areas like kitchens or bathrooms, or less frequently in rooms that aren’t used every day.
Outdoor lighting should also be checked regularly, especially if it’s exposed to insects, moisture or dust. Sensor lights, porch fittings and security lighting can lose effectiveness if the globe or fitting is dirty.
Extra tips
- Avoid touching halogen or incandescent globes with your bare hands—oil from your skin can damage the surface. Use gloves or a clean cloth when handling.
- Don’t overspray cleaning products near light fittings, as moisture can get into the socket or wiring.
- Always check the globe for cracks or wear while cleaning—if it’s damaged, replace it.
- Take care when cleaning around high ceilings or decorative fittings. Some complex installations, like track lighting, may require special tools or professional help.
In summary
Keeping your light globes clean isn’t just about appearances—it’s about maintaining efficiency, performance and safety. With just a few minutes of care every few months, you can brighten your home, extend the life of your globes and reduce unnecessary energy use.
As with any home maintenance task involving electricity, caution is key. Always turn off the power, allow the fittings to cool and avoid using excessive moisture. For anything you’re unsure about, especially when it involves high-voltage wiring or difficult access, get advice from a licensed professional.
