CFLs are not dsimmable! W Their RF/transforner ckts are not meant for use on dimmers! That's a real good way to start a fire, AFIK.
I own/rent property and have put in dimmers everywhere to prevent CFL/mercury hazard from CFLs. hen my tenants move in, they get halogen bulbs for every installed light fixture. My rules ban the use of CFLs. If the halogens burn out, they supply incandescents or halogen replacements. Once every year, they get a free halogen for any fixture that they had to provide an incandesct.
Halogen bulbs have the old incandescent screw bases and bulb shape, with another, smaller bulb inside that profile. these halogens have filaments and are dimmable. They give the same light on 40% lower power as the same incandescents.
Remember, in the winter, the heat generated from any bulb warms the house and reduces the fuel bill. Filament lights only need extra energy for cooling in the summer, not the winter.
GET THE HALOGEN BULBS.
I like Halogen bulbs, and have several fixtures that use them.
I’d only dim that old nondimmable cfl for a few seconds. Just to freak my friends out, cuz the light from them was truly disgusting, and to implant in them the suspicion that cfos were crap! I was on quite a “crusade” against those awful bulbs!
