Why is my light dim when I turn it on?
If your lights flicker or dim whenever you turn on an appliance (e.g. a washing machine, vacuum cleaner, or microwave) then you’re beginning to overload your circuit. Each home electrical circuit has a limit on just how much power it can draw. The lower current flow leads to dimmer lights in the room.
What causes LED to dim?
It could be a number of things. But most commonly, LED bulbs may flicker or dim in your home when there are voltage fluctuations in your home’s wiring. When electrical loads turn on and off in your home, this creates a change in voltage levels, which may cause the LED lights to occasionally dim or flicker.
What happens when you dim a non dimmable LED?
If you use non-dimmable LEDs on a dimmer, what happens? The bulb will not dim properly. The circuitry inside non-dimmable LEDs won’t be able to handle low or pulsing current levels and will eventually become damaged, because they are only designed to be either fully powered ON or off.
Why are my lights dim when I turn them on?
When a new appliance is plugged in, especially ones that draw in more electricity when they are switched on than when they are running, the demand of the circuit increases, and this can than cause your lights to dim. To fix this problem, call an electrician who can install dedicated circuits as one solution to this problem.
What to do if your lights keep dimming?
If your lights are continuing to dim for a long period of time and there is no pattern that you can see causing this, it may be best to call your electricity company (i.e. FPL). They may not be supplying at the norm you are used to due to an issue on their side.
Why does my house light keep getting brighter?

Why does my vacuum cleaner dim when I turn it on?
Vacuum cleaners use a lot of electricity and starting yours up may cause the voltage to temporarily drop. This might also happen with other appliances, devices or equipment that use a lot of electricity, such as microwave ovens or hair dryers. As long as the dimming is slight and doesn’t last, this is usually not a cause for concern.

Can a bad dimmer switch cause a circuit to fail?
You mention that this happens with one circuit only, so that will be our focus. The possibility of a bad dimmer switch can be easily tested by simply replacing the dimmer switch with another dimmer or a standard light switch just to see if the problem still exists.
