Light Bulb Flickering when Turned On | What Shall I Do?

If you are the type of person who is worried about the flickering of your light bulb and want to resolve this problem, then don’t worry, we have got your back; in this article, you will find more about the reasons that cause the flickering and its solutions.

The Issue with the Bulb

Ensure the bulb is securely attached if the flickering is restricted to a single light source. Although it may appear simple, the bulbs can become loose over time and lose their connection to the socket. Tighten the bulb if necessary. If it fails, you might try replacing it.

The flickering might be caused by the type of bulb used.

Fluorescent bulbs

They tend to flicker, exceptionally when turned on or in low weather. If your fluorescent lights sometimes flicker, it’s generally nothing to worry about.

Dimmer switches

Dimmer switches are the most common source of flickering. Dimmers are intended to control more oversized electrical loads and don’t always work well with lower-voltage LEDs.

Faulty Light or Fixture Switch

Flickering can be caused by a faulty connection between the light or fixture switch and the bulb. Swish the button gently to check whether it generated a flicker. If it does, you’ve discovered the source of the problem. If your light is already flashing, try switching the switch on and off to see if that resolves the issue. The problem is the switch, which should be changed if it does.

Overloaded Circuit

Have you ever observed that when a significant electrical device (such as your air conditioner or washing machine) is turned on, the lights flicker, blink, or dim? Your issue might be an overloaded circuit, which means these appliances use more current than the circuit can manage.

If the flickering occurs regularly, is intense, and does not stop immediately, there is an issue. The problem might be with the appliance itself. For example, when a bearing fails, the motor will use a more significant current as it tries to start. Alternatively, there might be too much sensory stimulation on the same circuit. Make an appointment with an electrician to determine the root of the problem.
This may not be a problem if the flickering is occasional, minor, and occurs momentarily when the appliance is turned on. When large electrical appliances are turned on, they draw more current. This generates a voltage loss, which causes the lights to flicker or fade. Minor flickering of this type can occur even in a well-designed electrical system with big loads on its circuits. The better the system’s design, the less noticeable it will be.

Voltage Fluctuation

Another source of flickering lights is fluctuating voltage. When you switch on a huge appliance, the lights constantly flicker, and the flickering continues even after the device has stopped functioning. Unpredictable, surprising dimming and frequent light burning are signs of fluctuating voltage.

Slight variations are typical, but your home’s voltage should always be between 115 and 125 volts. A voltmeter may be used to set the voltage in your house. If your results average more than 125 volts, then you’ve discovered the source of your flickering lights. An electrician can determine the best solution to your voltage issue.

Loose Wiring Connections

Loose wiring is not just a source of flickering lights but also a significant cause of house fires. The issue may be systemic, but it is always harmful. Wiring, breakers, switches, and old and out-of-date connections are always a source of concern. Another leading cause of home fires is faulty wiring.

Arcing can be caused by loose connections in an outlet, lamp, or switch box when the electrical current “jumps” over gaps in the relationship. This is a significant cause of electrical fires. A loose circuit connection causes a high resistance point, which leads to hazardous point heating. A single faulty link might compromise the entire system.

If you’ve seen an increase in flickering but haven’t adjusted to your electrical system, it might be due to loose wiring. A switch failure, loose fixture wiring, worn connections in the breaker box, or loose service wires in the main electrical panel are all potential locations. Call an electrician right away if you suspect weak wiring or haven’t located another source for your flickering lights.

If the flickering is limited to a single lamp, look for loose wiring. Before removing the fixture, turn off the light at the circuit breaker. (If you are unsure how to accomplish this, do not try!) If the institution looks loose or unstable, contact an electrician immediately. Call an electrician if it doesn’t work, and you haven’t located another source for the flashing. Wiring issues should not be overlooked.

Electrical Usage from Neighbors

Because your house most likely shares a transformer with neighboring homes, their loads influence your power supply. A neighbor’s excessive electrical use might cause your flickering lights. If the problem persists, an electrician is your best bet for discovering the source.

If your neighbors’ lights are also flickering, there might be an issue with the electric utility service itself.

What can I do to stop my lights from flickering?

When dealing with this issue, you may always try replacing your old light with a new one. If you haven’t already, now is a fantastic time to transition to LED lighting. LED lights come in a broad range of forms and sizes, so you should be able to locate the ideal LED replacement for your needs. Ensure the power is switched off and the bulb has cooled down before replacing it. If your light continues to flicker after you’ve replaced it with an LED, you’ll need to explore alternative options.

Last Words

Flickering lights are a common problem for many individuals and one of the most irritating lighting problems. Flickering lights may create the right atmosphere in horror films, but they are not something you want in your home or business. Flickering lights do not contribute to the safety and comfort of our homes and workplaces.
