That is some serious backpedaling from your earlier assertions. Thanks

They do not seem to do 60 watt but our local high street electrical

I don't have a way of quantifying it, but a continous source is much easier
for me to use as a reading lamp. So a 20 watt halogen lamp on "low" is
easier to read than an 11 watt flourescent at the same distance.

Farther away it works the same way too, but I no longer have an incandesent
lamps except for special purpose ones (reading lamps, photgraphic safelights,
etc) to do an eaual distance comparison.

That's my biggest problem with CFL's. I can live with the color problems,
I can live with the slow startup, but what bothers me is the extremely bright
end sticking beyond the fixture causing my eyes to compensate when I look in
that direction, making the rest of the room too dark until I look away and
they recover.

It's very annoying that while I have several globe fixtures that perfectly well
took 75 watt incadescent bulbs, there are no similar CFLs. Even the short
curly ones don't fit in the same space once they get beyond the equivalent
of a 40 watt incadescent bulb. :-(

Also what do you put in a refrigerator?????

Yes indeed - I am colour blind, and if that is what makes the difference
between someone who does have an issue with CFLs, and someone who doesn't,
then 12% - one eighth - of the population being forced to suffer because

It is difficult to specify a "color temperature" for a non-continuous
source.

The bare bulbs look "white", leaning a bit to the warm side.

With all due respect William, that is the most feeble justification that you
have come up with so far. It's like the government banning cars and making
everybody buy bikes instead, and then turning round and saying that riding a
bike is still better than when you had to walk before the bike was invented
... If it has taken 15 years so far to get these dreadful things from
total crap to utter crap, then by the time they are actually at a point
where they can properly replace incandescent lamps, I will be a pile of dust
anyway. I'm afraid that I cannot, by any stretch of my imagination, equate
"60%" and "30 seconds" to either "instant" or satisfactory replacement
technology. If they really were 'good', they wouldn't need defending against
all of the criticisms that are levelled against them by (colour blind ??)
people the world over.

I assume you suffer from protanopia or deuteranopia. My father did. (I
don't.)

I worked with a guy with that problem. One day he asked me to help him pick
colors for a Web site. It was causing him all kinds of confusion. I showed
him a fluorescent-green pen, and asked him what color it looked to him --
"Orange". (That doesn't mean he saw it in the way a person with normal color
vision would see orange. Rather, he could not distinguish it from what we
would call orange.)

Peter Wensberg, the author of "Land's Polaroid" (a beautifully written and
wonderfully entertaining book) told how, during a lunch of Chinese takeout,
Dr Land administered one of the standard color perception tests (the kind
with colored circles, where you indicate which letter or number you see).
Wensberg utterly flunked it, getting every one wrong.

I've lived with fluorescent light for more than 60 years, and have never
suffered (except in my early days at Microsoft, when the office lights gave
me (and some others) headaches). It appears to me that your suffering is
primarily aesthetic.

I'm not backpedaling in the least. They do, indeed, come on instantly. You
ASSUMED that "come on" means "light at full brightness".

Consider tubular fluorescent lights. Many DO NOT come on instantly. But when
they do light, it's at full brightness -- at THAT instant, which could be
considered the point of turn-on.

Refrigerator bulbs represent such a small percentage of energy consumption
there would be no point in switching to CFLs.

Once the color problems with LEDs are solved, there will no doubt be an LED
refrigerator lamp.

Very Orwellian, and I suspect this is just the tip of the iceberg.

Rather than fawning all over the "royal couple" (it's hard to imagine a
more worthless set of parasitical leeches than the "royal" family), it may
be time for the Brits to start planning revolution.

Of course we have our own problems with these enviro-nazi types on our side
of the pond as well. When a ban on incandescents was planned here I stocked
up and have a basement with a lifetime supply of good ol' 100 watt bulbs.

That's an interesting point. If 12% of the population is aflicted with a
gentic disorder, or one caused by a disease or trauma, then the National
Health should provide them with incadescent bulbs and a susbidy for
electricity to run them.

I know the US has the "Americans with Disabilities Act" that would require
it, and I'm sure there is something in British or EU law like that.

I would persue it based on what the National Health does for people
with macular degeneration and work backwards. At what point is the
inability to see defined and where does color blindness affect your
daily life.

Besides outdoor lighting where I needed hundreds of watts of incandesent
lighting, I used the first for indoor lighting in places that
traditionally have lights on timers. In a windowless bathroom an 8 watt CFL
provides enough light at so low a cost I just leave them on.

After all a timer uses electricty too, and figuring out when to have it go
on and off without leaving people in the dark is an art.

We don't turn lights on or off during the Sabbath, and used to leave the
main light in our apartment on all Friday night. We installed a timer
to turn it off at midnight (when the last of us goes to sleep) and on again
at six AM, (when the first of us gets up), but it will take 200 weeks
to even out the cost of the timer and installation versus the cost
of electricity. By that time, we will have long since moved out. :-(

There are small LED replacements that may fit a refrigerator.

I have several motion sensor lights in my house so I don't have to
search for a light switch when I have my hands full, or I'm half asleep.

That 'schematic' appears to show two manufacturer's options, the first being
the three pin bi-colour LED that you currently have fitted, and the other
being two single colour LEDs - one in each of the hole pairs below the three
hole set. One thing that you might like to bear in mind is that a blue LED
requires approximately twice the voltage across it to illuminate
satisfactorily, than does a red or green or yellow. This may or may not be
an issue, depending on how the original LEDs are driven. I'm basically with
everyone else. You're asking how to fit triangular wheels to your car, but
nor telling us why exactly you need to do it ...

H = head and C = combo.

Thanks to the help of this group, I shunted two 82 ohms and two 220
ohms to get the 41 and 109 values. Thanks to Ohmite for actually
selling a product where I did not need to buy 50 of something to get
some decent precision resistors. Digi Key and Ohmites 40 series was
the deal. The 150 ohms was a off the shelf gift.

Yes, I do need to do a full cal but this ancient repair just swung the
