Dimmers are devices that are used to lower the brightness of a lamp or light. The dimmer allows you to control the voltage applied to a bulb by lowering or raising the intensity of the light output. Dimmers can be as small as the size of a light switch, or very large in the case of architectural lighting installations and large theatres. Small dimmers are usually controlled directly or with a remote, while larger ones run on a much wider system. Dimmers used to be built from variable resistors, but recently they have switched to semiconductors because they have a much higher efficiency.

Considering the amount of money dimmers help you save on electricity, though, it may be worth the investment.
