Hi...

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!
