Overloaded Circuit Large electrical appliances draw more current as they start up. This causes a voltage drop, which results in the flickering or dimming lights. Even in a well-designed electrical system, with large loads on their own circuits, some minor flickering of this nature can happen.
Why do lights flicker after turned off?
Flickering can also occur when a LED lamp is switched off. This might be due to possible returns of currents from drivers, power supplies or transformers in the system itself.
