Why is my light bulb flickering?
No need to be an electrician to know there is something wrong when your light bulb is flickering, but what exactly?
What is light flickering?
Flickering lights is an issue many people encounter and is one of the most annoying predicaments possible with lighting. Flickering lights may create the perfect atmosphere in scary movies but, in real life, it's not something you want. Lighting is meant to keep our homes and workplaces safe and comfortable and flickering lights don't do that.
What can I do?
When facing the problem, you can always try replacing your old light with a new one. If you haven't already, this may also be a good time to switch to LED. LED lights are available in a wide variety of shapes and sizes so you should be able to find the perfect LED replacement to suit to your needs. Before replacing a bulb, make sure the power is turned off and the bulb has cooled down. If your light is still flickering after you've switched to the new LED one, you'll have to look for other solutions.
What is causing the flickers?
There are several reasons that lights flicker including things like a drop or variation in voltage that makes the lights dim for an instant. When trying to identify the cause of the problem, it's important to consider a number of things including the following:
Type of lighting
It's common knowledge that fluorescent tubes flicker when they start up and, in general, they are more inclined to flicker than other types of lighting. A number of other factors including things like the temperature, the age of the tube and the functionality of the ballast and starter can all contribute to fluorescent flickering.
If your fluorescent light only flickers when you turn it on, this is normal and there's nothing to worry about. You can always consider an LED alternative, however. Not only are they far more efficient than fluoresecent tubes, they light up instantly without any flickering. Why not check out our range of LED tubes, LED panels or LED CFL bulbs.
Dimming your lights can cause flickers. That's because lots of dimmer switches, and older ones in particular, are designed to handle higher electrical loads. Trying to dim low-voltage LED lights with a high-power dimmer switch can cause flickering, therefore. You should always check that your dimmer switch is compatible with the light source you're using.
Flickers can also be caused by faulty connections in light fixtures themselves as well as between the fixture and the light source or even the wiring.
If you're unable to determine the cause of the flicker or you've found the cause but are unable to solve it yourself, we recommend getting a professional to help.
