Well, CFLs are not ideal for all lights. CFLs won't work properly with any light that uses a dimmer of any kind, or any light that is on a motion detector or low light sensor trigger because those things do not completely cut off power to the bulb. With incandescent bulbs this is not a problem because there isn't enough power to light the bulb, but with CFLs, the electronics which are in the base of the bulb will get damaged.
I have CFLs for all of my light bulbs, but for my fixtures which are on dimmers, I stick with traditional incandescent bulbs.
Will that remain legal in the future? (I didn't have any of my cfls on dimmers, BTW.)
