I understand that many facilities with a large number of lighting
fixtures (whether fluorescent or incandescent) will figure out a
schedule according to which they simply replace all the bulbs/tubes at
once rather than have to keep coming back and replace one or two here
and there. Costs less in the long run.

I talked with a guy in a large department store replacing flourescent bulbs
about the 1-2 problem. He said a failing bulb also extinguished the good
bulb but his procedure was to rather than try to find the bad bulb to simply
replace them both as they are cheap and aged at the same rate so that the
"good" bulb was nearly aged out anyway.
