Some fluorescent lamps (bulbs) can be dimmed, but they must be designed to be dimmable. The ballasts and electronics that drive the bulb have to be designed to work with a dimmer or they will not function properly and may overheat.

When dimming fluorescent bulbs, many can't be faded smoothly from full to zero. Some will only go to a minimum like 5-20%.

A dimmable compact fluorescent lamp will be labelled as being dimmble and can be connected to an ordinary dimmer. For tubes, the ballast has to be specailly designed to be dimmable.

Incandescent can be used with a dimer switch. Flourscent lamps, unless designed to be dimmable, cannot due to the ballast needed.
