remote dimmer capbilities
Many manufacters getting smart with this set up and if your remote dimmer is not designed to work with CFL then you have to stay with insdentscent bulbs and per engery pact they still have extempt for ceiling fan rated bulb so you can still get them.
Here one thing you can try is keep one insdentscent bulb and replace the rest with CFL that should keep from getting any flicker if the CFL is rated for dimming purpose.
Hope that help ya on that question.
The answer will be based on NEC ( National Electrical code ) or CEC ( Cananda Electrical code ) or ECF ( Electrique Code France )
