How Does a Dimmer Switch Work?

Dimmer switches work by altering the voltage that is supplied to the light source. Pulse width modulation (PWM) technology is used in this process. PWM works by rapidly turning the power on and off to the light source. The duration of the power relies on the brightness of the light; the shorter the power is on, the brighter the light.

What type of dimmer for LED lights?

You should use a dimmer switch that is specifically designed for LED lighting to ensure compatibility and optimal performance.

Will any light bulb work with a dimmer switch?

No, not all LED bulbs are compatible with dimmer switches. Make sure that the LED bulbs that you choose are dimmable.

How many LED lights on one dimmer?

The wattage of the bulbs and the wattage rating of the dimmer switch determine how many lights you can connect to a single switch. Check the manufacturer’s specifications to ensure that you do not overload the dimmer switch.

Does a dimmer switch require special wiring?

No, you can use the same wiring that is used for regular light switches. To avoid electrical risks, it’s necessary to ensure that the wire is securely connected and insulated.
