    Not too sure on this one, but they will probably work. You just won't get the full brightness out of them.

    Depends what type of lamp and fixture they are. 277 Volt flourescent probably won't start; Don't leave them connected if they don't start; their balasts will need around 260v to initiate, and they can be damaged by trying to start.

    Halogen or other incandescents will work but will be dim.

    I don't know about High pressure sodium and others.
