Why Is My Light Bulb Flickering?

Listed below the 5 most common reasons behind your flickering light bulb:

1. Loose Connection

When we see a flickering light bulb, the first thought that comes to our head is if it is connected the right way. It is indeed one of the most common reasons, and you should immediately check the bulb and its connection. You will need to check the socket and see if your bulb is fitted properly. In this regard, it is best to periodically disconnect and reconnect the bulb to prevent a lost connection.

The lamp might fall someday, and while setting it back up, the bulb might loosen. So, check if the bulb is flickering fast and repetitively, as that would mean it is connecting and disconnecting constantly. This indicates that there could be some other issue with the bulb. However, if you nudge it and it flickers, the connection may be lost, and you might just have to tighten it.

One good thing about fixing a loose bulb is that it's a pretty straightforward process, and you can do it yourself. Just switch off the circuit and tighten the bulb so that it is securely connected to its holder. The bulb needs to be cool enough to start working with as otherwise, you might end up burning your fingers.

To properly tighten the bulb, simply turn it in a clockwise direction. At the same time, don’t apply too much force as otherwise, you might break it. Once you are done, switch on the blub to check if the problem has been solved.

2. Problematic Circuit

If there is no problem with your bulb, the wiring of your house might be the reason behind its flickering. There could be a case of a bad connection with the switch, and you might have to replace the switch to get it fixed.

To find out, just wiggle the switch a little and see if it flickers. You might also have to press the switch hard to stop the light from flickering, and that would mean there is a problem with your switch. If this happens, call a professional electrician, who might repair or replace it depending on the seriousness of the issue.

Other than that, it’s not unusual for people to see multiple lights flickering at the same time, which can happen due to an overloaded circuit. And if the problem goes unnoticed for too long, it can cause severe damages.

As you may already know that every house has a number of circuits, which deliver a specific amount of electricity. So, if you have too many things plugged in the room, then the circuit might not be able to handle the demand, and lights may be affected.

For example, you may have walked into the kitchen and turned on a high-power mixer just to see the lights dim immediately. This is because the mixer may require a huge amount of electricity, which may compromise the supply to the lights.

There are more chances of this happening if the home wiring is old and is not made to take on heavy power demands. In such cases, electricians might change the service panel, and that would provide more amperage to your house. Hence, it would prevent the lights from flickering while you work with high-power appliances.

3. Burned Out Bulb

Have you tried reconnecting the bulb, but it still keeps flickering? Yes, we hear you, and we know it can be irritating after a point, especially if it has been bought just a few weeks back. But it could be faulty or might have burned out before time.

Other than that, there could be problems with contact, the receptacles could be worn out, or a bad filament may contribute to its flickering. That being said, it generally happens when the bulb is old or expired. Hence, we will always recommend checking the manufacturing date while purchasing a new one. Try to avoid a bulb that was manufactured long back as chances are they would malfunction sooner than later.

The other problems that could cause issues with the bulb are constant wear and tear or improper voltage. Plus, if you often shift the bulb from one holder to another, be very careful while connecting and disconnecting it from the socket. Ensure that no part is damaged as that could also lead to flickering.

And if wiring has become faulty or was of poor quality in the first place, it could lead to the burning out of the bulb in a very short span of time. This may also happen if the voltage supply is inadequate.

Also, remember that older lights are more prone to burning out or flickering. If you’re dealing with an old bulb, try reconnecting it to the socket a few times and see if the light output is stabilized. If not,it is time to get a new light.

4. Faulty Light Fixture

While there is a greater chance that the light bulb is causing issues, it might be wrongfully blamed. Yes, it might be working fine, while there could be problems with the fixture. Just disconnect the bulb from the existing fixture and connect it to another one. If it works fine, then you will know what to blame!

If the fixture is old and worn out, a repair or even replacement may be required depending upon the extent of the damage. We believe it is best to call up professionals who will assess and do the job for you. You shouldn’t wait for too long before you get it fixed, as a faulty fixture might cause bulbs to burn out much faster.

5. Blinking LED Light

The recent trend of shifting to LED lights has worked well in saving electricity. They are efficient and long-lasting units that ensure you don’t have to spend on replacement bulbs too often. However, before shifting to LEDs, there is one thing that you need to pay attention to and that is a dimmer switch.

If you’re already using a dimmer switch, then check if the bulb that you are purchasing is compatible with that. In case it is not, the light might keep flickering without any reason. Here, we should also mention that there are dimmable lights available on the market, so check the product description before purchasing.

If you are unsure about which one to pick, it is best to get in touch with a professional electrician who will provide you with the best suggestions regarding new lights. Take their opinion, and you should have a proper light that works fine without flickering.

It’s Time To Fix Your Flickering Light Bulb!

It is best to get flickering bulbs repaired (or replaced) immediately if you do not want to live in the dark. While the problem may be very simple, it could also be due to a low power supply, and that could interfere with the entire house’s electricity circuits.

That said, we will recommend first trying to disconnect and reconnect the bulb before calling for professional help. You might not need to spend on repair at all, and the problem could be solved in a matter of minutes. And no, there are no spirits in the house, so you can sleep peacefully!
