Why Won't My Dimmer Switch Dim the Light?

A common problem with a dimmer switch that does not dim the lights is that the user has switched from incandescent lights to compact fluorescent or other types of energy saving lamps. Older dimmer styles are not compatible with the newer lamps and often do not work at all. If dimming the lights is important, EnergyStar recommends switching to a compact fluorescent dimmer switch and dimmable CFLs.
