Are all dimmers 3 ways?

You will need a three-way dimmer and a three-way switch. This lets you dim from one location and turn the lights on and off from another.

What is the difference between LED dimmer and incandescent dimmer?





They don’t control as well as the new dimmers that are designed for LEDs and it will also drastically shorten the life span of the bulbs. With old incandescents you are just reducing the voltage across the element but with LEDs you are lowering the voltage to the electronics which fire the LED.

What kind of dimmer is needed for LED lights?

LED bulbs have a low wattage, so you’ll need to have a dimmer that is 250W or 400W and ideally intelligent trailing edge, for smooth dimming. See our full range of LED suitable trailing edge dimmer switches.

How do I know what wattage my dimmer switch is?

150 watt rated dimmers are usually for a single bulb. Wattage rating is usually on a sticker on the light fixture.



Multiply result by 125% (1.25).

  2. 300 watts x 1.25 = 375 watts.
  3. Next higher wattage dimmer rating = 375 watts or higher (600 watts).

Do I need a special dimmer for LED lights?

Yes, LED lights require a special dimmer. An old fashioned incandescent dimmer switch will not work properly with LED bulbs. You cannot just simply lower the voltage to the LED driver.

Can you put a dimmer switch on any light?

A dimmer switch can be installed anywhere that an existing on or off switch is in place. Replacing the current toggle switch with a dimmer switch will allow you to change the lights’ brightness, so long as you are using a light bulb that is compatible with the dimmer you have chosen.
