I haven't tried the CFL outside but I had regular Fluorescent lighting
in a barn and when below 32F they didn't work worth a damn.

I think we're are going to transition to the more expensive LED lighting
bit going from $0.30 bulbs to $6.00 bulbs would be a hard sell so the
CFL is an intermediate to acclimate the consumers.

Incandescent lamps are too futuristic for most of us, stick to whale
oil or kerosene lamps. Only greenies like incandescent lamps.
progressives like you. They'll never come down in price and be
cheap like the old kind we've been using for the past 500 years.

Dollar Tree? Cool Hand Luke movie was filmed not far from Stockton.

There is a Dollar Tree store in that strip mall next to the Walmart
store, that is a mile and a half South of doggy's couch.That Walmart
store is where I do my food shopping.

I have to get out and about tomorrow morning anyway, Ergo my old house
has PEX plastic water pipes and the outside water faucet has done sprung
a pinhole water leak.To repair that water leak, I could call a plumber,
but I like to do things myself, so that means I am going buy a crimping
tool (about $100.00 more or less, but a plumber would charge me about
that much or more to come out here and fix that water leak for me
anyway) and some copper rings and a Go - No Go gauge.If I get any more
PEX water leaks, I can allways fix them myself.

While I am out and about (He says, Where is Elmo? She says, He is out
and about) tomorrow, I might stop off at that Dollar Tree store.

Mr. Black,

The same can be said for all the new High MPG Cars
and Hybrid Cars : The Energy used to Build the One
'New' Car and All of it's Parts could Fuel a currently
existing Car for 3+ Years by some estimates.
-so- Keeping the Old Clunker has an overall Energy Use
Avoidance in the First Year that extends out 3+ Years
-and- Keeping the Old Clunker for 3+ Years can Reduce
the Carbon Footprint for a Decade.

LEDs are "more efficient" ... but only if you narrow
your definition considerably.

LEDs require precision engineering to make ... and
that costs money and energy and toxic crap that has
to be specially disposed.

WHITE LEDs suck ... they're really a BLUE LED with
a pinch of white phosphor material stuck on. The
problem is that the phosphor has a limited - in
some cases VERY limited - lifespan. Then your LED
gets dim and/or takes on weird colors. Not really
an issue for flashlights ... but for home lighting
that's on for hours per day every day - problem.

So why not use red + green + blue LEDs to get
white ? First of all, each color uses a different
voltage, complicating design. The processes used
also vary, so making a sheet of alternating R/G/B
emitters is a super pain in the ass.

Finally, next time you're out and about, look at
the LED lights in the traffic signals. Oh wait,
you'll probably have trouble finding GREEN ones
because GREEN LEDs are unreliable for some
damned reason (I recall a Scientific American
article a year or so ago explaining why). So,
after a year, you'll have a Red/Nothing/Blue =
icky purpleish light instead of a nice white light.

The hope for LEDs lies in the "organic" variety
that can literally be "printed" onto a plastic
sheet using tech fairly close to an injet printer.
They won't be AS bright as the old kind, and they
won't last AS long ... but they'll be a lot CHEAPER
so you can afford to replace dimming elements.

Give these about another three to five years. By
then the cost/performance/efficiency should be in
the acceptable range.

Not meaning to hijack, but I am concerned that eventually, when I have no
choice but to use CFLs, my SW radio listening will suffer. It's my
understanding, that they contain a 'mini-starter' which emits RFI. I've
experienced problems from flourescent fixture starters that I've replaced
which will randomly blank out any AM transmissions. Flicking the light
switch off, then on corrects it temporarily.

Anyone comment on the CFLs?

CFL's and long tubes can be radically different animals. One is a
linear noise source, so the attenuation with distance is
proportional, whereas CFL's represent, more or less, a point source,
so attenuation is proportional to the square of the distance. In
other words, CFL noise falls off more quickly.

CFL technology can also be quiet different than long tubes. And,
with a quality bulb, inherently lower noise.

Early CFL's were quite noisy. Current production CFL's tend to be
much quieter, although cheaply made CFL's can still produce small
amounts of noise. At a distance of a couple of meters, the noise is
not an issue, but cumulatively, they can raise the overall noise
floor in your location if many are used.

The good news is that cheap CFL's don't last very long, and must
be replaced often until they're gone.

The better news is that with an external antenna of some quality,
worked against a good ground, the raised noise floor can be both
avoided, and/or overcome.

Average citizens cannot be trusted with economic decisions that
require balancing immediate costs and long-term benefits, according to
environmentalists.
