Dimmer switch doesn't work with the new CF light switch.

Question

I have a 2 pole dimmer switch that controls 6 40 W bulbs. For energy savings, I switched the incadescent bulbs to the 40 W CF bulbs.

They all light up, but now will not dim with the same dimmer switch.

Are there special dimmer switches for the CF bulbs or what is happenning?

Answer 1

3. Can I use a compact fluorescent light bulb with a dimmer switch?

To use a compact fluorescent bulb on a dimmer switch, you must buy a bulb that's specifically made to work with dimmers (check the package). GE makes a dimming compact fluorescent light bulb (called the GE Longlife Plus Soft White Energy Saving Bulb) that is specially designed for use with dimming switches. We don't recommend using regular compact fluorescent bulbs with dimming switches, since this can shorten bulb life. (Using a regular compact fluorescent bulb with a dimmer will also nullify the bulb's warranty.)

Answer 2

Standard CF bulbs will not work with dimmer switches. They have an electronic ballast which will only operate at a single voltage level, and attempting to use them with a dimmer can cause a fire. There are specially designed CF bulbs for use with dimmers, if you wish to use those - however, they are more expensive.
