Lights Flickering

Flicking lights can be annoying and can take quite some time to ascertain the cause of flickering lights in the home or in the work place.

Why do lights flicker? The reason lights flicker can be down to a number of different causes from a fluctuating voltage to mismatched dimmer switches, faulty LED chips of some thing else.

Some lights naturally flicker but this is not normally noticeable, this is due to the flicking being at around 50Hz / 60Hz, the same frequency as AC (alternating current) electricity.

To find the cause of the lights flickering a number of tests will need to be carried out. To investigate the reason why the lights are flicking you should instruct an electrician to investigate the flicking lights at the reason why they are flickering.

Always seek expert advice from a professional if your lights flicker, flash, blink, strobe or randomly go on and off, there could be an electrical fault which needs urgent attention.

Flicking lights could also be the result of poor maintenance.

Always seek expert advice for any electrical issues.
