Dimming flourescent lights

Are flourescent light dimmable? I.E. 2- 4' fixtures that are switched.

You must buy a special ballast (one that indicates that it can be dimmed), and a special dimmer (one that indicates that it is for a fluorescent fixture). Neither ordinary fluorescent fixtures nor ordinary dimmers will work.

there are also some flourescent lights that are not dimmable.
for those that can, a dimming ballast is many times more $ than the whole fixture.

Figure minimum $90.00 per ballast, $50.00 per dimmer (from Grainger catalog, page 782).

Another option is to rewire the fixture with two ballasts and two switches, one for each lamp.
