If you have CFL lamps you may find that will work at 120v (though not much lower) even if it says 200/250v on them.
On a recent visit to Nepal there were frequent power cuts (referred to as load shedding). When it came back on it was initially about 110v, the lights worked, the fan turned very slowly, and the air con would not start up.
