If you’re removing a light and leaving the box in place, you can cover it with a ceiling cap.

1. Turn off power at the breaker and confirm the light is off.
2. Remove the fixture and gently pull wires forward.
3. Cap each wire separately with appropriately sized listed wire connectors.
4. Tuck wires neatly into the electrical box without pinching.
5. Attach a blank cover plate (also called a ceiling canopy) using the box’s screw holes so it sits flat.

Choosing a plate wide enough to hide any cosmetic gaps can help the ceiling look clean. Don’t bury or drywall over the box; it usually needs to remain accessible. If you’re unsure about wiring or your local code, consider a licensed electrician.

Working with wires calls for caution. These basics can help guide a safe approach:

1. Shut off power at the breaker and verify with a non-contact tester if you have one.
2. Separate conductors (hot, neutral, ground). Trim damaged ends if needed.
3. Use listed wire connectors sized for your wire gauge; twist on until snug and no bare copper shows.
4. Cap the ground as required or bond it to a metal box per local code.
5. Neatly fold wires back into the box without strain and install an approved cover.

Some people add a wrap of electrical tape over connectors, but appropriately sized connectors are designed to hold on their own. If you encounter aluminum wiring or uncertain conditions, consulting a licensed electrician is advisable.

You’ll see a few names depending on the setup:

• Ceiling canopy/cover plate: The round plate that covers the electrical box for pendants or flush mounts.
• Bowl cap: A small finishing cap used on some ceiling fan light kits when a bowl or kit is removed.
• Recessed light cover plate/trim: A plate or spring-mounted disc that hides or finishes a recessed opening.
• Light cover/diffuser/lens: The dome, globe, or panel that softens and spreads the light.

On Walmart.com, you’ll find options across these categories—round canopies, decorative hole cover plates, and replacement domes or diffusers—so you can match the part to your fixture style and ceiling opening.

Start with measurements, then pick an attachment style that fits your ceiling:

1. Measure the opening: Note the diameter of your ceiling box or the hole you’re covering.
2. Check compatibility ranges: Many plates list the hole sizes they cover (e.g., 3–4 in). Choose a diameter that fully overlaps the opening.
3. Match mounting: Screw-on plates use the electrical box’s screw holes; spring/buckle styles suit recessed or glass openings.
4. Consider material and finish: Metal canopies offer durability; plastic plates are lightweight and easy to clean.
5. Mind clearance and heat: Keep space from hot lamps and avoid blocking ventilation.

Picking the right size and mount can help achieve a clean look without patching drywall.

Often, yes—if you proceed carefully and the mounting is straightforward.

1. Turn off power and let bulbs cool to avoid burns.
2. Support the cover with one hand while releasing screws, clips, or by gently twisting if it’s a bayonet-style dome.
3. Measure the old cover (diameter, depth) and note how it attaches so you can select a compatible replacement.
4. Choose material: Glass offers a classic look; plastic or acrylic can be lighter and more shatter-resistant.
5. Install the new cover and confirm it’s secured evenly without over-tightening.

If hardware is worn or missing, replacement clip or screw sets may help. For complex fixtures or uncertain mounts, a professional can assist.
