There are some flourescents that do work with dimmers. You have to look for them.
They DIM? They may work but in an either on or off mode. I thought that fluorescents produced light from the ionized gas which is either in an ionized state or not; a binary state. There may be enough current through a dimmer switch to fire the gas into an ionized state, but not t modify the output except for off.
Please correct me if I am wrong.
