Flickering Lights
Lights usually flicker because of a failing globe, an LED that does not suit the dimmer, a loose connection in the fitting or switch, or a problem with the supply. One flickering light is often the globe or fitting. Several lights flickering together, or flicker that comes with buzzing, heat or a burning smell, needs a licensed electrician.
Flicker is one of the most common lighting complaints, and the cause is often minor. The pattern of the flicker is the best clue to where the problem sits.
This guide explains the usual causes, what you can safely check, and which signs mean it is time to call an electrician.
01 / Detail
If only one light flickers, the globe, the fitting or its switch is the likely cause. If several lights flicker at the same time, especially when a large appliance starts, the problem is more likely on the circuit, at the switchboard or in the supply.
02 / Detail
Many LED globes are not designed for older dimmers. The result can be flicker, buzzing or lights that never fully switch off. Replacing the dimmer with an LED-compatible model usually fixes it.
03 / Detail
A loose connection in a fitting, switch or junction can cause intermittent flicker. Loose connections can also create heat, which is why they should not be left.
04 / Detail
With the light switched off and cool, you can try a new globe of the correct type. Do not open fittings, switches or the switchboard.
05 / Detail
Call if flicker affects several lights, continues after a globe change, or comes with buzzing, heat, discolouration or a burning smell.
Frequently Asked Questions
A failing globe is not. Flicker caused by a loose connection can create heat and should be checked.
The dimmer is probably not compatible with the LEDs. An LED-rated dimmer usually solves it.
Large motors draw extra current when starting. Frequent or strong dimming is worth having checked.
Yes. If neighbours see the same flicker, contact your electricity distributor.
