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.
