Dimmer switches can create a good ambiance in dinning room or a home theater. Installing them is also not a cumbersome task. But before purchasing it, you should have a basic knowledge regarding them.

You can use 120V incandescent bulbs and halogen bulbs along with these dimmer switches but you can’t use fluorescent bulbs and most compact fluorescent bulbs.

The basic reason behind this is that dimmer switches are meant to work with bulbs with wire filaments, which are present in 120V incandescent and halogen bulbs. On the other hand, fluorescent bulbs and compact fluorescent bulbs contain a gas that requires certain amount of voltage to operate the light. Also for low voltage halogen bulbs, a special dimmer switch should be used.

Generally, there are single pole and 3-way dimmer switches. Choose the appropriate one for your application. If you want the light to be turned on via a single switch then you need a single pole dimmer switch and if you want it to be turned on by two switches then you need a 3-way dimmer switch. Note that in a 3-way lighting application only one of the switches can be a dimmer switch.
