Understanding a Flickering Light

Understanding a Flickering Light

When we think about some common problems around the house, we don't often think about the small stuff: leaky faucets, long-term wood damage, or burnt-out light bulbs. But this "small stuff" is actually the exact kind of home repair that will consume most of your time unless you understand what they're caused by and how to fix it. At the head of this list of the "small stuff" around your house? The flickering light.

A flickering light seems like a simple problem, but it can come from a variety of causes. If you're going to understand your home electricity systems, you'll need to know just how and why these different causes effect the light, and what you can do to ensure a safe and proper repair. Let's take a look at some of these causes.

First, it's helpful to understand that it's relatively normal for a light to flicker, usually due to the nature of voltage traveling through wires - the flow won't always be stable, especially if there are other factors that are taking away "juice" from the circuit. This is why many homes are designed with two different types of circuits: larger main circuits for the appliances that will use up larger amounts of electricity, and secondary circuits for simpler devices like light bulbs. Today's modern homes have largely solved the problem of noticeable flickering due to inconsistent voltage flow.

It's important to remember that a flickering light isn't necessarily a harmless problem. Circuit connections that are broken can lead to heating at certain points in the circuit, which obviously can lead to injury or even fires. That's why you won't want to let your light flicker endlessly - at the very least, inspect the situation. A switch that is failing can also have the same problem - if you are unable to find the problem there is a possibility you have not inspected the light switch.

Some problems leading to flickering lights are less sinister. There might be electrical effects from outside electrical loads which can even come from neighboring houses.

Because a light is not simply a bulb, but the result of electrical wiring and circuitry that go into your home, understanding a flickering light is about more than understanding the bulb. You have to know the potential dangers of electrical wiring behind the scenes and what a flickering light might indicate. If you have any doubts, call in an electrician to fix the problem and answer your questions. You can at least learn some things about lights that you'll be able to use in the future.
