Depending on the type of light fixture you’re setting up, it’s not always possible to get the perfect fit.
This can lead to a situation where the light fixture looks odd, out of place, and simply unappealing visually. This is why more and more people try to be careful when choosing a new light fixture for their room.
While it’s always best to find the perfect fit, you will also want to learn how to fix a light fixture that does not cover the hole.
If a light fixture does not cover the hole, this means the hole needs to be patched or covered using an external solution. The two options you can consider are a plaster patching compound or a decorative ring that goes around the light.
To do this the right way, it’s best to start with a decorative ring depending on how big the hole is. If it’s too big, you will need to move forward with a plaster patching compound to fill the hole.
This should be a good fit as it will be easy to apply and is going to provide a smooth finish without taking away from the light fixture itself.
This guide will explain both options and what to do if a light fixture does not cover the hole entirely.

How To Fix Light Fixture That Does Not Cover Hole
1. Turn Off The Power Source
Before doing anything with a light fixture, the first step is to always turn off the power going to the light.
This can be done by accessing the breaker panel.
You will want to find the breaker that is connected to this part of the property. Toggle it off and make sure there is no power going through to the outlet by turning it on and off at the switch.
If there is no power, the light will not turn on.
You are then good to go with the next step.

2. Set Up Decorative Ring (Solution 1)
Your first option is to look at a decorative ring.
This is a simple ring that is going to go along the base of the light fixture. By doing this, you are essentially covering up the hole that is sticking out from the sides.
A decorative ring for a light fixture works depending on how big the hole is.
If the hole is too big for the ring then it is likely not a good idea. You will have to determine this by pinpointing what works for your specific situation.
It’s also recommended to look at the rest of the layout in your room before choosing a decorative ring. It has to make sense with the appearance of the room.
3. Fill Hole With Plaster Patching Compound (Solution 2)
The next option is to fill the hole with a plaster patching compound.
What this is going to do is fill the hole and create a seamless finish that is unnoticeable from far away.
To do this right, you are going to need to place the light fixture in place and then see how much of the hole is left sticking out. This can help begin applying the plaster patching compound into place.
Be thorough and spread it evenly to get the desired finish.

4. Let The Compound Dry
When you have applied the right plaster patching compound, it is time to let it dry.
This should take up to 24 hours depending on how much of the compound has been applied. Please note, you should not attempt to turn on the light fixture while the plaster patching compound is drying.
While the light fixture will still work, it is not recommended to do this.
The reason is to ensure the light fixture does not get ruined and/or moisture doesn’t go into the wiring nearby.
Be thorough and let the plaster patching compound dry.
Final Thoughts
These are the main options available to you when a light fixture does not cover a hole.
To fix a light fixture that does not cover the hole, you have two choices. The first option is a decorative ring that goes around the base of the light. The second option is to apply a plaster patching compound to fill the hole.
Both options are valid and will work as long as the hole is covered properly.
If the hole is too big, you won’t have any other option than to use the compound. The decorative ring won’t be big enough to cover the hole and that will render it useless.
