Greg I wondered about that too. The life of a tungsten filament [at design temperature 3100º-5400ºF] is a factor of surface damage to the filament, at a heat approaching the fusion point of tungsten [6192ºF] and by cyling on and off. Minute cracks and 'hot spots' appear, which slowly enlarge and lead to failure, buffered by the choice of inert gas fill, argon, nitrogen, halogens. If this 'laser surface' treatment is degraded by the heat in less than the normal bulb life, the whole idea will be useless.
