Operating line voltage limits
To receive the full benefits of rated lamp light output and to prolong
generator life, it is essential that the voltage supplied to an
installation be maintained within the prescribed limits.
Low voltage has no damaging effect on the generator. It could,
however, have an adverse effect on lamp performance and starting
dependability.
Subjecting a ballast to excessive voltage will cause early ballast
failure.
