He is right, the stresses involved in the turn-on of the bulb each
time is equal to several hours of continuous running. If you cycle a
bulb on and off every few seconds, the total on time before the bulb
fails will be only a few hundered hours for a 1000 hour rated bulb,
It would be a strange way to rate the life of a lamp - on constantly,
since this pretty well never happens.
Do you find the 'flasher' lamps on your car failing more quickly than
similar lamps which don't flash?
