I am not inherently opposed to CFL's. As a matter of fact, when they
first appeared on the market I rushed out and bought some even though
the prices were about $8-10 each. You got a 100W equivalent of light
for about 25W of energy. For me this was in the early 1990's.
Frankly I think those early ones with the long straight tubes were much
better than the new curly ones. I have a couple in service, rather
intermittent, that are at least 15 years old.
However, my present life expectancy for the current crop of CFL's is
about 6 months as measured by putting the date on each bulb as it goes
into service. At this time I have replaced almost every incandescent
bulb in my house with CFL's. About the only exception is some outdoor
flood lights. Where I have indoor flood lights in overhead lighting, I
am using CFL's
I track my energy use every month with a graph of KWH used. If I factor
degree days into my energy consumption to remove the effect of the AC
unit, I find there hasn't been enough reduction in monthly energy usage
to buy a 6 pack of beer once a month.
Given my experience with short life, the one that overheated and started
smoking, and concern about the mercury involved in each bulb, I don't
think I am ready to wholeheartedly embrace their complete adoption. I
know, I know, there has been mercury in florescent bulbs and the world
hasn't come to and end. However, the biggest use of florescent bulbs
has been in commercial and industrial areas where disposal is *somewhat*
controlled. What could happen when billions of these things start
showing up in land fills. Some people will dispose of them in a
controlled manner. Most will toss them in the trash.
Maybe my experience is an anomaly in the march of progress. But if it
isn't, the only beneficiary of a change from incandescent bulbs to CFL's
will be the manufacturer of them.
