Aside from being annoying, flickering light bulbs can sometimes be a cause for concern, indicative of bigger electrical problems that could cost you money or pose as a fire hazard.
Here are some common reasons behind flickering light bulbs:
A Loose Connection
The most common reason why your light bulb is flickering may be because it’s screwed in too loosely into its socket, causing it to periodically disconnect it from its power supply.
For most lights, this is a no-brainer. Just make sure to switch the light off before you attempt to tighten the bulb. Also put on a glove before you grasp it, because it’s likely to be hot. If the light still continues to flicker, your problem lies elsewhere.
Faulty Lighting Installation Switch
Other reasons why your incandescent light bulb is flickering may be contact problems, worn-out receptacles or bad filaments. These problems often occur as a result of wear-and-tear or faulty wiring inside the fixture.
Firstly, make sure that the cord plug isn’t the source of the bad electrical connection by making sure it’s in good shape and not loose in the electrical outlet. You can also troubleshoot the connections by toggling the switch; if the lights dim when you do this, it’s likely you have a bad switch, in which case you should consider hiring an electrician to closely inspect the faulty switch.
However, if the problem is the bulb’s filament, it’s relatively easy and cheap to simply replace the bulb.
If you notice your lights dimming briefly when high wattage appliances—such as refrigerator or microwave ovens—are turned on, this might be because the voltage in your home is fluctuating a lot. Simply put, this means that your electrical circuit is overloaded and there isn’t enough current available to power all the lights.
Recent electrical codes state that high demand appliances should be served by their own dedicated circuits. However, in older homes, it’s common for large appliances—like the dishwasher or refrigerator—to be served by the same circuits that serve your lighting fixtures, causing the lights to dim when these appliances kick in.
Another sign of frequent voltage fluctuation is if your lights frequently burn out.
While a little voltage fluctuation is normal, your home should be supplied with voltage between 115 and 125 volts. Consult with a professional electrician to check the voltage in your home with a device called voltmeter.
In case you use high wattage incandescent bulbs, your electrician might suggest replacing them with low-wattage LED bulbs that draw less power while providing the same illumination.
