Very good point, here in Nashville we have relativly high line voltsge - I routinely measure 127.5VAC; I tried 130V lamps but they are too dim for good illumination except as hard to access fixtures where changing them is a greater inconvenience.
I used to see excessive voltages most of the year until the local power co. put in a higher capacity subfeed to my neighborhood. The older wimpier connection suffered enough voltage drop that in order to keep the system from brownouts in the summer it would go up to 130 volts at less heavily loaded times.
