    Anyone happen to know what the diff is between
    dimmable cfl's and the regular ones?

    Friend has a chandelier with half a dozen bulbs in
    it, and would like to use cfl's. Confusion is that
    the dimmable ones cost about 4 times as much, and
    regular ones work real real wierd :)

    Thanks, and take care.

    If you look up ballast controller chips and look at the datasheets you'll
    see the difference. The dimmable ones are quite a bit more complex, they use
    a somewhat different power supply design and they provide a separate voltage
    to keep the cathodes in the tube heated when the tube is dimmed. I have a
    few and they're mediocre, they're large and clunky and flicker if you dim
    them too far but they worked ok in the rec room in the last house I lived
    in. In the one light in my house that's on a dimmer now I use incandescent
    lamps, it's not on very much anyway.

    That's the difference.

    Use incandescents. 10 for a dollar at the dollar store. CFL's are fine for
    on off - a bad choice for dimming.

    BTW dollar store cfl's have appreciable QRM.

    I don't doubt it. They also don't like low temps and have a crappy
    phosphor - but what do you expect for a buck?

    BTW, I just found 4 X DVD-Rs with full jewel case in my local store!
