I was under the impression that the way to make a bulb last for a good 
long time is to under-run it -- to run it off a much lower voltage than 
designed. I bet if you took a modern (110V) bulb and powered it off, say, 
90V, it would have a long life.

Of course if you do this you get a lot less light per watt of electical 
input power. 

Photofloods (do you get those in the States?) are the reverse. Bulbs that 
are deliberately overrun to give a high light intensity (and higher 
colour temperature) than normal bulbs of the same power. The trade-off is 
a very short life -- a couple of hours for some of them.
