My Dad says that the voltage indeed was 220/110 way back when, and he still calls it that, even though it's 240/120 now and has been for decades.
*gets up and actually measures wall socket voltage, returns with 122.5*
130 volt bulbs are made, as far as I recall, for areas that have voltage that fluctuate, or will indeed last longer as they're not being fed the "full" 130 volts. I may be wrong, but an approximately 5% reduction in voltage will increase service life by around 15-20%.
