Doug,

It is interesting that you point out the 'spousal effect.'  I also have
that.  I thought I would be sharp and replace the lights above the kitchen
table with mini-CFL's.  I don't think the boxes even cooled down before the
CFL's were back in them.  I am not going to say any more....

Yes - take a magic marker and write on the smoke detector batteries and CFL
& LED lamps.  Been there, done that!

Regardless, this has been an illuminating topic.

Steve

Subject: Re: [TN] what is the reliability of CFLs and LEDs as incandescent
light bulb replacements?

My experiences are similar to Steve's, but not quite to that extent.  I
don't find them reliable and too many that I bought were DOA out of the box
and returned.  Then when they do burn out prematurely, we can't dispose of
them easily.

On the other hand, my wife hates them with a passion (brightness and
spectrum) which may be the bigger reason why they are not used in my house.

I did convert my Christmas lights from incandescents to LEDs about 7 years
ago and I have yet to have them burn out and I really noticed the drop in
the energy bill during that time.  As Rigo said, heat kills LEDs.  Well, we
don't really have to worry about that in Iowa in December.

I have one of the LED bulbs currently on trial in my house.  So far, it has
outlasted all the incandescent bulbs, though it is not as bright as I would
like.

Brian,

Wow!  The only 'early ones' that I could get were made to the West of the US
[across a large pond], and they were not cheap! 

I remember in one purchase, I had 50% mortality just getting them home. 
The store asked me what I had done with them? ... took them out of box and 
screwed into socket.  Didn't work!!!   Here I am!  Had to expend an 
Additional significant amount of fuel and time to return them.  Suggested
that they take the rest of the shipment and put them back into the shipping
container and send them back to point of origin.  My 'environmental savings'
had long since been flushed away.

  I prefer the cool white [daylight] bulbs vs the dim 'warm' ones myself...

I remain cautious about putting them in enclosed fixtures and/or continuous
use applications.  Certain brands are on my do-not-use, or use-with-caution
list.

I still remain skeptical about how much additional Hg was released into the
environment by less than intelligent, frustrated consumers in the maddening
rush to 'save the environment.'
 
Even though prices of CFL's have come down and reliability has gone up, they
are still not particularly cost effective for many of my 'typical' 
home-use applications.  Your situation, on-the-island, could be different,
however.  IMHO, 'Feel good' still remains a large factor in many cases. 
LED luminaries are just way too expensive yet!

I agree that early CFLs were terrible for domestic use. Several years ago,
being a professional environmentalist, I changed nearly every bulb in the
house. I was disappointed because of 50 Hz flicker (well, 100 Hz really!),
poor lifetime, cold light, long start-up time, poor reliability and high
cost (about the equivalent of $10 each). They were all made in the USA (I
was told the European ones weren't available). I think I must have taken
20 back for guarantee replacement. 
Little-by-little, they were replaced by European and Chinese ones with warm
phosphors, faster start-up, high-frequency (flicker-free) "ballasts" 
with minimal mercury and 1/3 of the price. These seem to be lasting their
advertised lifetime -- can't really say, as I've replaced only one in ~5
years. I'm now entirely satisfied. I'm also amazed at the great variety of
shapes, styles and sizes that are sold now, including traditional
bulb-shaped ones. I recently installed a new light and went to Leroy-Merlin
for a decorative CFL; it took me half-an-hour to find what I was looking
for, such was the choice. I would guess they must have had 200 or more
different types of CFL on their shelves, which occupied a whole aisle.

Have any of you torn one of them apart to see how well they are made? 
You'll be amazed at the poor quality of the components in a lamp that's
supposed to have a 10 year life.
