Nice theory, er...except that a bulb is switching off and on 60 times a second anyway, in harmony with any arc.

Exactly what I had in my mind.
Also how does a modern dimmer 'dim' a standard incandescent lamp?
It chops the heck out of the sine wave.
These dimmers
prolong the life of the lamp.
I really do not think you will be shortening the life of a typical incandescent lamp unless you switch it off long enough for it to substantially cool down. I would think of and on periods of a couple of seconds would shorten the life.
