Back in the old days, a voltage reduction to 160 volts would have been obvious due to the much reduced brilliance of incandescent lamps, and fluorescents would have been either very dim, or failed to light at all.

These days however, many LED lamps are multi voltage and give full light output down to 90 volts or so. As do a minority of fluorescents.
