Larry, European light bulbs have always been similar to other incandescents-- well, maybe not the Chinese ones-- so their "lifetime" depended on the AC line voltage they were operated on. In fact, their lifetime varies inversely as 1E12. That is to the 12th power! I ran across this data from GE way back in the '60s.
