Is there anything I can do to eliminate it, short of switching
back to the old filament type

No easy way. You are better off with the incandescent bulbs as
those screw type florescence are a mercury hazard and depending
on the instillation they will not last long.

The best use for the energy efficient bulbs are ones that are
not switched on/off often and are mounted upright. That
eliminates most uses.

A better system would be low voltage quartz or LED type
lighting but that takes rewiring the house.

Incandescent bulbs release way more mercury than the occasional
broken CFL.

You will have to explain that one.

I turn mine on and off just like any other lamp; *no ill effects.

If you use them upside down in any ceiling fixture you will shorten
the life of the bulb.

I use them vertically, horizontally, and at various angles
in-between. Again, no ill effects.

If you are turning them on and off all the time you will shorten
the life of the bulb.

There are LED lamps that run on 110 VAC.

Those have switching power supplies that should be avoided.


Indeed. We found out the hard way with our patio light, it is upside
down. After going through three bulbs in 7-8 maybe nine months, I
switched. Maybe the moisture of being outside also had something to
do with it.

That is true what you said, I've never read that but the two bulbs we
do use in the house are vertical and we leave them on all the time
and as far as I know not one of them has expired yet.

I'm still waiting for Dave to explain the mercury in an incandescent
bulb.

The socket at the top configuration subjects the electronics and the
filaments to more heat, aging them faster.

Starting the bulb up puts a lot of stress on the circuits and filaments,
actually the only time they are really used, and wears them out.

The bulbs don't like repeated hot to cold temperature extremes either.
