1. Have you really done the HONEST research into their longevity. I
don't think so. They never last as long as what the package says.

I have heavy experience with them, and with some exceptions notably to
avoid, in my experience over 95% of the time they give most of their
claimed life.

2. Have you done the HONEST research as to the harm that is inflicted
on the environment in manufacturing and disposal versus the benefits
when compared to the manufacturing harm and disposal of incandescent
bulbs? They contain mercury as an example.

Modern CFLs of 60 watt equivalent or more reduce mercury pollution even
if they are broken and all their mercury is sent to the environment after
only half their claimed life. This is because about half of electricity
generation in USA is from burning coal, the biggest source of mercury
pollution.

3. Have you done the HONEST research if these light bulbs will be able
to replace the incandescent in every application, in every fixture, in
every circumstance.

I know for a fact that they are not good everywhere that incandescents
are used. However, they are good for most places where incandescents are
used. Applications where CFLs are bad for replacing incandescents have an
extremely high rate of using incandescents of types exempted from the
upcoming ban.

Sometimes they fall apart in your hand while you're trying to screw
them into the socket

If you overtighten them while screwing them by the tubing rather than by
the base region.

and you cant use a dimmer with them are some examples.

Dimmable ones are a little common already.

4. Have you done the HONEST research into the economics of cost of the
light bulb versus the savings? Anything other than an 8 watt bulb
which is about as effective as the light bulb in your oven costs at
least seven dollars. How much in electricity will I be saving if I
paid so much for it?

A $7 CFL lasting 5,000 hours and reducing power consumption by 45 watts,
at USA national average residential electricity rate of 11 cents per KWH,
saves $17.75 even if the incandescents cost nothing to obtain.

Meanwhile, I find it easy to find CFLs $7 or less in up to "100 watt
incandescent equivalence" (26 watts), and $6 or less in up to "60 watt
incandescent equivalence" (13-15 watts). Even in 1-packs in major chain
drugstores and supermarkets.

In packs of 3 or more, they usually cost near or under $5 apiece,
sometimes around $2 apiece.

5. They will not fit into many fixtures designed for incandescent
bulbs so you have to buy whole new fixtures.

"60 watt equivalent" spirals that fit everywhere a 60 watt A19 fits are
common. I have yet to find a fixture that is rated to allow a 100 watt
A19, that a 100 watt A19 fits in, and that fairly common 26 watt spirals
do not fit in.

Have you done the HONEST research as to how much the environment is
going to be harmed by the manufacture and replacement of all those light
fixtures so they can use these idiotic bulbs?

Let me put it this way...

OSRAM, who manufactures incandescent, fluorescent (both CFL and long),
and LED screw-in light bulbs did a study that determined that 98-plus % of
the life cycle energy consumption of incandescents, CFLs, and LED screw-in
light bulbs from manufacture through disposal, including transportation, is
from the electricity consumed during their rated life.

As for fixtures - I have yet to see any residential fixture replacement
being done to accomodate replacement of incandescents with CFLs, and not a
lot in commercial buildings either.
