result is greater power consumption overall.
Here's an interesting bit of opposite experience. When I had a
restaurant, I had a walk-in freezer. I wanted to know when the
compressor was running so I wired a light socket across the compressor
contactor coil terminals and located it where I could see it from the
dining room where I sat when not busy.
I tried all sorts of light in that thing. Long life, rough duty, pilot
light, none of them could stand the 2-3 times an hour cycling. Then I
installed a little 7 watt organ pipe CFL. It lasted over 5 years and
was still going strong when I closed the restaurant.
Add that to the mandatory drop of mercury in each, and I really can't
see how they can sell them at all.
Now Chuck, don't go getting all chemophobic on us now!
I got two for "free" from my power company (They hid the charge on my
bill, until the courts made them reverse it...) and included with the
CFL's was an elaborate procedure for cleaning up a broken CFL. It involved
opening all of the windows, and leaving the room for a couple of hours,
and then, with a gloved hand putting the pieces on newspaper, and folding
the newspaper up and putting it in a 1 gallon zip lock baggie. To clean up
the broken bits, you are supposed to vacuum the area with a fresh vacuum
cleaner bag, and then put the vacuum cleaner bag in a ziplock baggie, and
take the remains off to the hazardous waste disposal facility.
That's embarrassing to read, it's so stupid. Like some meaningless
worship ceremony to mother Gaia or something.
Geez, there's less than 10 milligrams of merc in a "100 watt" CFL. That
is a harmless amount, especially considering that elemental mercury is
fairly harmless.
What'll they come up with next, HAZMAT team if you spill some paint thinner?

If the intention is to cleanup the mercury rather than just the glass
and relatively non toxic phosphor then the cleanup procedure is contrary
to the method outlined in:

If one is paranoid about mercury spills sprinkling the debris with
flowers of sulphur is a good idea especially if one intends to
repeatedly break CFLs in the same location.
