It's a function of the ballast--there are dimmable ballasts and
dimmers for fluorescents. It's not a new technology, when I was in
high school in the '60s the auditorium had a dimmer on a set of
fluorescents (and I don't mean something somebody bought at the
hardware store--they were separate from the house lights and
controlled by the same panel as the stage lighting).

You probably need a different brand. Mine work fine, even come close
to duplicating the color change in incandescents.
In any case, the dimmer being part of the wiring is a concept whose
days are numbered--you can buy bulbs at Best Buy right now that screw
into an ordinary socket and dim and adjust color temperature under RF
control. They're expensive now but ordinary LED bulbs were expensive
five years ago.

I saw something about color change last time I visited an electrical
supplier, but I thought that required an entirely new system: dimmers,
lamps, and wiring. Are you saying that there are LED lamps that change
colour (i.e. get redder) when dimmed? If so, that'd be wonderful;
even though new LEDs are dimming better, the lack of colour change
means that even a 3000K lamp looks blue at low levels (especially
next to a halogen on the same circuit).

See http://www2.meethue.com/en-us/about-hue
As I understand it, it doesn't automatically change color when dimmed,
but you can get the effect by adjusting the color yourself when you dim
them. I assume these use separate RGB LEDs rather than a phosphor (I
don't see how else you can get the color change), so I'd expect terrible
CRI.

Here's an example:
< http://www.homedepot.com/p/Philips-60W-Equivalent-Soft-White -Clear-G25-Dimmable-LED-Energy-Star-with-Warm-Glow-Light-Eff ect-Light-Bulb-459339/206514311>
Note that my dimmers are supposed to work with CF bulbs--sometimes
they did, sometimes they didn't. I haven't tried these or any other
CF with an older-technology dimmer so can't say for sure that you'll
get the same result but for 7 bucks I'd say it's worth a try.
They don't dim down quite as far as the incandescents (I'm replacing
incandescents in that fixture as they burn out) but close enough.
The keyword you want, from Philips anyway, is "warm-glow".

Different product. You can emulate the effect with Hue (note that
there are several Hue variants, some that dim only, some that dim and
adjust color temperature, and some that are multicolor) but the ones
I'm talking about, also from Philips, aren't Hue, they may have some
of the same technology under the hood but they don't have the RF
control--the color change is automatic with the dimming.

That's what I've noticed with them. At least the new ones aren't
flickering as badly at low settings.

The URL didn't work, but I'll look for "warm-glow".

Yes. I recently replaced 7 65W floods with the equivalent "warm-glow"
lamps. They are actually a bit brighter than the incandescents they
replaced and produce a pleasant light while dimming, but they don't go quite
as dim as the incandescents. (On the other hand they don't "sing" when dim
either.)
I was planning on attrition for replacing the old bulbs, but the provincial
government offered a temporary incentive that brought the $6.99 price down
to $0.99 (Cdn). At current electricity prices this made economic sense even
if the LED's last just 1000-2000 hours like the incandescents.
I am no great fan of CFL's but some have worked well in some situations. I
find that most have not lived up to promised lifetimes. And at -30 C they
are reluctant to turn on, even slow at +10 C in some cases. For some reason
cool whites work better than warm whites in cold conditions. When my supply
of CFL's run out they will be replaced by LED's which keep getting better
and cheaper.

The only place where I miss having the CFLs is in the bathroom. The slow
ramp-up to full brightness by CFL lamps is useful in the middle of the night.

Soft start dimmers on LEDs are not as slow as CFLs, but they do take the
edge off the instant BLAM! to the eyeballs ...

Stick a big capacitor across the LEDs - wbo done.

That requires taking the bulb apart and finding a place to put the
capacitor. Or do they still have DC mains where you live?

No, but all my LED lighting runs off a 12V DC supply.

Then you are talking about something different from the rest of us,
who just go down to the store and buy 110v or 220v bulbs and screw
them into the sockets from which we had just unscrewed CFL or
incandescent bulbs.

when my brother built his 3rd house, he put a skylight in the bathroom
so he wouldn't have to blinded during the night.

Yep, that's missing out on half the advantages of LEDs.

That's the kind of thing that lights my house, but those prices are
daylight robbery!
I pay €10 for a 5m roll of high efficiency 5630s (room lighting)
running at 4.5W/m or €8 for 2835s (halls and small spaces) at 2.5W/m (both
60 LEDs per metre) from a local (well in the country) supplier. Our kitchen
(4.5m x 6.5m is very brightly lit by three four metre strips of 5630s.

In our master bathroom, there are eight lights over the top of the large
mirror. There are six CFL's and two LED's. The LED's make the room
bright enough during the couple of minutes it takes the CFL's to reach
full brightness.
The two LED's are enough to light the room alone, but having six empty
sockets would look shabby... the wife's *not* going to like that!

Yeah, Axminster shops are risky places to visit with a full wallet and
they give Veritas (and Lie-Nielsen) stuff a special tool pr0n corner;
it's nice to look but easy to resist as I wouldn't do any of it justice.

I do like my L-N low-angle jack, and I use the Veritas scrub and
skew rabbet planes frequently. But, as you say, they'll empty a wallet
in no time.
