Basic dimmer information

So let`s go over the basic information and determine the type of dimmer you should get.

Single-pole dimmers are used for lights controlled from a single dim switch in one spot. Example of a Leviton single pole dimmer.

Types of dimmer switches

Universal Dimmers

Universal Dimmers are used to control halogen, incandescent, dimmable CFL and dimmable LED bulbs.

They offer maximum-range dimming, soft start-up, and eliminate flickering of lights. When using CFL or LED bulbs with a dimmer, check that the packaging on the bulb shows that it is dimmable. Most bulb and dimmer manufacturers gives bulb compatibility information on their sites.

Halogen and Incandescent Dimmers

Halogen/Incandescent Dimmers are used to control halogen and incandescent bulbs. You are not supposed to use them to control CFL and LED bulbs or dimmable CFL and LED bulbs. If you use them for that, it may result in bad performance.

Electronic Low Voltage Dimmer (ELV)

ELV Dimmers are used to control electronic low voltage transformers and dimmable LED power supplies ex. ELV track lighting, Led strips and under cabinet lighting . For installation ELV Dimmers needs a neutral wire.

Magnetic Low Voltage Dimmer(MLV)

These Dimmers are good for recessed lights which are often magnetic and low voltage. Magnetic low voltage lights are often heavier and larger than electronic low voltage.

Fluorescent Dimmers

Fluorescent Dimmers are used to control fluorescent lights.

High Wattage Dimmers

These dimming devices are used to control high wattage lighting, mainly 1000 W. If you have a fixture with over 600 W your choice should be a HWD.

An important thing to remember is that, use only one type of bulb in a lighting fixture, otherwise it may cause some trouble in performance.


Dimmer switch wattage calculation

Now you`re maybe wondering, but what about wattage?

Choose the perfect dimmer switch

Dimmers come in many different wattage models. The most typical dimmer wattage ratings are 150 watts, 300 watts, 600 watts and 1000 watts. 150 watt rated dimmers are usually used for a single bulb. You can find the wattage rating usually on a sticker on the light fixture.

Dimmers are built to control many wattage loads and levels. You should select the dimmer by your wattage requirements. The calculation could not be easier. Here`s how you calculate it.

Do like this:
Add the total wattage of the bulbs you want to dim. Like this, a fixture with three 50 W bulbs has a total wattage of 150 W (3 bulbs x 50 watts).
You can use a 200 W dimmer or bigger in this case.

What about when you have 2 dimmers then?

You calculate it the same way. Say you have six 50 W lights in a room, but they are split, there are 3 lights per dimmer.

First dimmer: 3 x 50 W=150 W

Second dimmer: 3 x 50 W=150 W

You will need two 150 W or bigger dimmers in this case.

What dimmer switch should i use?

In conclusion:

Determine the number of switches that control the light group. If only one switch controls the light, purchase a single-pole dimmer. If two switches control a single light or a group of lights, you will need a 3-way dimmer.

Then look at the bulb type you are going to be using and pick the right type of dimmer. The universal dimmer model will do it for most locations.
