However, there is a new breed of flurescent lights that will work with a dimmer, they are special bulbs. I am not positive, but I believe all the dimmable units are a compact fluroescent bulbs not the more common tube units with special ballasts.
This question is related to the houseboat, so every tiny bit of power i can save the better. I understand that compacts are not as efficient as tubes (power used light ratio) so i was looking at 18watt tubes
Yes Vin,
You CAN dim Flourescent lights. You will need a special dimmer, and change all the ballasts in the fixtures. Additional wires need to be run between the dimmer and the fixture as well. With all the money you have to lay out up front, it will take years to pay it back with any (if any) savings.
Besides, the light from a dimmed flourescent isn't that great. I know I'd never try it in my house.
Not sure if all your lighting is floro- but you can by compact floro's at the depot and walmart that are dimmable and screw into to regular 120vac socket by GE. The Packaging doesn't say on the outside if it will work with a standard 120vac dimmer or not. Try the GE website or sylvania they may have some ideas for you. I would agree with the comment that most floro light once dimmed is not so great... My co sells a dimmable set up and I promise you you don't want to buy commercial stuff ouch.... The link here goes to GE's dimmable compact... GE
