How to fix light flickering & dimming in the house?

When your lights flickering or go dim, there are a few things you can do yourself to try and address the problem, but it’s important to know that under the law in Australia you are not allowed to do any repairs or electrical work so once you have tried the things you are allowed to do, then it’s time to call your friendly electrician in Palm Beach to have your wiring checked.

What can cause lights to flicker?

Generally, flickering light is caused by a fluctuation or drop in the voltage in a circuit. When you understand some of the most common specific causes, it gives you an idea of the best methods to solve the problem.

Bulb Type

Fluorescent light is usually more likely to flicker than LED or other bulbs. This can be caused by the age of the bulb, the temperature and the bulbs warm-up cycles. Usually, a small amount of flickering should not be of concern unless it’s constant or the bulb starts to dim, then it needs to be replaced.

If a new bulb flickers or takes a long time to start up, then it suggests that the starter, which sends a steady stream of electrons between the two filaments is faulty. The ballast controls the amount of current that is sent to the filaments. If this is faulty, it will allow too much current which may vaporize the filaments or even cause the bulb to explode. Often it is best to call your electrician and have the whole fixture replaced.

Dimmer Switches

Most conventional types of dimmers are designed to be used with incandescent light bulbs and if used with LED bulbs can cause flickering. One solution is to purchase a good quality dimmable LED bulb or ask your electrician in Palm Beach to replace your older type dimmers with the newer styles of dimmers that are designed to be used with LED bulbs. These dimmers still require dimmable LED bulbs, but this should fix the problem.

Loose Bulbs

When light fittings get old and worn they can become loose, screw bulbs, if not tightened firmly, can have a week electrical contact causing flickering. The only thing you can do with a bayonet or conventional fittings is have your electrician replace them. With the screw in type of fitting simply tightening the bulb so it’s firm.

Faulty Connections

Any loose or faulty connections in your light circuit can cause your lights to dim or flicker. Sometimes you can test the switch by turning it on and off a few times and noticing if it feels or appears faulty, but in any event, you will need to call your electrician as this can present a significant fire and safety hazard.

Large Current Draws

If your lights dim when your refrigerator or electric oven turns on, then you have overloaded circuits and need to have your local electrician in Palm Beach check your wiring.

Normally in a modern home, there should not be any issues with flickering dimming lights, but in older homes this can be a serious issue and you need to have your local electrician check your wiring as it could be unsafe and dangerous.
