Wait until they find out there is arsenic in LEDs!

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?

Having looked at the circuitry, I can't see any real reason why cycling
would be hard on the usual CFL. The filaments glow red the entire time
they are on anyway, and the inverter is a simple FET multivibrator.
I think the reason people leave them on longer than the equivalent
incandescent is CFL's take a while to ramp up to full brilliance, and
they reason that at 1/4 the power draw, they are essentially free to
run.
In any case, I know I leave them on longer than I would if they were
instant on... for real, and EPA has noticed that others do the same.

Yes, and no. When mercury hits the ground, it splatters into hundreds of
miniballs of mercury. When you walk on them, they further fracture, and
by the time you are done, you have increased the surface area of the mini
drop of mercury greatly... probably thousands of times. That increases
the mercury vapor emitted into the room.
Is it harmful? Maybe. Maybe not.
What'll they come up with next, HAZMAT team if you spill some paint thinner?
As the laws are currently written, if you intentionally pour any amount of
gasoline, or paint thinner onto the ground you are committing a crime.

I think they might have gotten a little push back from the sheeple
if they suggested sprinkling any kind of chemical on Mom's carpet.

According to the paper that was linked earlier, there are 3 types of
fluorescent bulbs, some have no heater at all and are started with a high
voltage pulse that causes accelerated damage.
Those suffer from the most life reduction when cycled.
Those with the always on heater suffer the least, but are the least
efficient.

It's NOT "flowers" it "flour" of sulphur... as in a fine ground powder...
think wheat flour as is used to bake bread.

Among chemists, it's flour of sulpher. Flowers is an (incorrect & archeic)
popular name, like quicksilver.

When did this list become a discussion of Chemistry?
Is there a time list I can join?
Not that I've never been off topic, or never learned something
from an OT discussion, but this brings to mind dead horses and
the beating thereof. I'll bet there is a better list for this
subject, and that it's just full of shared ignorance.
