Flickering lights are common in many households although the cause may not be the same across the board. In some situations, the flickering may mean there is a serious problem with the electrical system which needs to be addressed by an electrician. In other situations, the flickering may not be as serious. The type of flickering and how often it happens needs to be considered in order to know how to address the issue according to your needs.
Causes of Flickering Lights
1. Flickering of All Lights
During stormy weather, it is normal for all lights to flicker in the house. This can also happen if you have recently made some changes in the electrical system and a problem arises. However, if none of these situations apply and all of your lights flicker often, then this is a good indication that there is a serious problem with the electrical system. The probable cause could be fluctuating voltage in your home. If left unrepaired, this can cause extensive damage to your home. It is in your best interest to contact an electrician as soon as possible to assess the situation. Before the electrician comes, you can take note of how often the flickering happens and provide those details to the electrician.
2. Single Light Flickering
There are several reasons why this may happen. One possibility is that you may have a faulty switch somewhere in your home. This is evident if the flickering still continues after switching the lights on and off a few times. For a normally functioning switch, the flickering would stop. Such cases require replacing the switch with a new one.
Another possible cause for flickering of a single light is a bad connection between the light bulb and the socket. At times, the bulbs may not be screwed in all the way thus causing flickering. To check if this is the problem, switch off the lights and unscrew the bulb then screw it back in. If the flickering stops, the problem would be a bad connection.
A faulty light bulb could also cause flickering. When most bulbs are about to die, they tend to flicker. The only solution is to replace it with a new bulb.
3. Flickering Lights Before Lighting Up Fully
A common case in households using energy saving bulbs is flickering of lights when they are turned on before lighting up fully. It happens often in these bulbs because they take time to brighten up fully. If the bulbs used are not energy saving bulbs, then you can conduct a few tests like the ones stated above to determine whether there is a problem with the switch or the bulb.
