Fluorescent Lights and 130V

A building I'm working at has some brick lights - j-boxes recessed into a
wall, and a cover plate on them - that illuminate walkways. The owners
have changed the incandescent bulbs to fluorescent.
I saw a note on the cover of a light that said the tested voltage was 130V.
Would a fluorescent light (small twisty bulb) be able to take 130V? Will
this voltage affect the life of the bulb?
I haven't tested to see if the voltage is indeed 130V, Thought I'd ask
here first in case there was something else I should look at, such as the
model number of the bulb.
Did the note actually say that 130 v is a measured value? In a small
enclosure like you describe using 130 v lamps on 120 v gives a
significant increase in lamp life, typically 2.5 x longer life. Yes, it
won't be as bright, but will still be adequate to illuminate a walkway.
CFLs in small enclosures fail quite quickly in my experience. They
don't have much life at high temperatures.
