Do you believe that 130V-rated (commercial?) incandescent lamps,
operating at ~120VAC, are longer-lasting enough to be worth the hassle
of getting them (wholesaler) and price, compared to an everyday bulb?

They are available at Lowes. You can also get Philips "/99" series
incandescents from bulbs.com - those are rated to last 2500 hours.

I recall that, some 30-years ago, I acquired one or more 130V-rated
incandescent lamps from one of the local, "city sales" wholesaler. I
don't remember following-up on the lamp's lifespan, but it was an
attempt to increase the operating life of a hard-to-reach lamp.

My biggest road block to converting to compact fluorescent lamps is that
all but one of my most-used light fixtures is controlled by a dimmer
switch that gets USED.

Target now has dimmable CFLs.

I need FILAMENTS to illuminate my home. A governmental mandate -
un-funded, I might add - to force me to convert to CFLs (beginning in a
couple years) is unconstitutional.

Home Depot is already selling incandescents with energy efficiency
improved enough to not be affected by the ban that starts in 2012-2014.
They are rated to last 3,000 hours and are dimmable. They are Philips
Halogena "Energy Saver".
