Can dimmer switch cause lights flicker?
One of the most common sources of flickering for LED bulbs is the use of dimmer switches
. The majority of dimmers are made to handle higher electrical loads. This means that the low-voltage LEDs may dim or flicker if they are connected to higher-power dimmer switches.
Why do my lights flicker with dimmer switch?
If bulbs connected to a dimmer are flickering, this is likely the reason why.

A standard dimmer switch cannot be used with an LED light as you will never be able to dim the LED light either completely or not very well.
LED lights need their own special electronic dimmer switch to have a fully functioning and dimming light
.
What happens if you put a non dimmable LED in dimmer?
Is it possible to dim them anyway? Simply, you can’t dim non-dimmable LED lights. If you use non-dimmable lights in a dimmer circuit,
they will either flicker or just run at full brightness
. They will likely burn out faster, too.
How do I know if my dimmer switch is LED compatible?
Check Your Existing Dimmer
The type of dimmer switch and it’s minimum/maximum load range will indicate the compatibility with LED light bulbs
. Trailing edge dimmers work best with LED light bulbs and leading-edge dimmers work best with traditional incandescent and halogen light bulbs.
What causes multiple lights to flicker?
If multiple lights flicker, this may mean you have
loose service conductors
in your main electrical panel or meter base. This can happen due to normal wear and tear as your conductors heat up and cool down each time you use them.
What do flickering lights indicate?

How many LEDs can I put on a dimmer?
A rule of thumb commonly used to calculate a load for LED dimmers is to
divide the stated maximum load by 10
. For example a 400W dimmer switch should have no more than 40W of LED bulbs connected to it, which would equate to eight 5W bulbs.
Can you use an LED dimmer switch with normal bulbs?
Use an LED Dimmer switch
If you dim a standard bulb such as halogen and the light intensity is reduced to 50% via dimming then the halogen bulb will give almost no light output, however if you do the same with an LED bulb the LED light will give 50% of its light capacity at its fullest.
Do you need special light bulbs for dimmer switches?
A dimmer switch can only support LEDs, CFLs and other lights that are made up of advanced technology and have a dimming feature
.
Can a dimmer switch cause a fire?
Dimmer switches can get extremely hot and possibly catch fire as well
. Therefore, it is advised to check the voltage mentioned on the dimmer switch and the bulb you are attaching to ensure that the dimmer switch will not get overloaded and potentially become a fire hazard.
What kind of dimmer switch do I need?
Choose a dimmer with a wattage rating that meets or exceeds the total wattage of all the light bulbs the dimmer will control
. For example, if the dimmer controls a fixture with ten 75-watt bulbs, you need a dimmer rated for 750 watts or higher.
What bulbs are best for dimmer switches?
Incandescent Light Bulbs
One of the most utilitarian bulbs, incandescent bulbs work with any dimmer switch on the market. Inside an incandescent bulb, electric currents move through a wire filament, which causes the filament, and therefore the bulb, to glow.
Can you put LED bulbs in any light fixture?
As long as the mounting base (socket) is the same size and type, you can use an LED bulb in an existing fixture
. If the mounting base isn’t the same size and type, the LED bulb will not fit the socket. You should never use a bulb with a higher wattage than what is recommended for the fixture.
Why are some light fixtures not dimmable?
Some Lights Aren’t Dimmable
These bulbs are designed to be entirely on or off, and they can’t operate on a dimmable circuit
. If you try to do it, you will damage the bulb. You will know that your bulb is damaged if you hear a flickering or buzzing sound. Many CFL bulbs cannot be dimmed, even on a dimmable switch.

Do old dimmers work with LED?
Traditional dimmer switches require a minimum wattage to operate correctly, and for this reason,
they may not work at all with LED bulbs
. If you find this, the only option is the replace the dimmer switch with one designed to work with LED bulbs.
What wattage dimmer switch do I need?
If you’re installing a dimmer switch, keep in mind that each switch is rated to handle a maximum wattage.
If you’re trying to dim six 100-watt lightbulbs, use a switch rated for at least 600 watts
