Are 277V lights wired the same as 120V?

The connection diagram is the same, one hot-leg and one neutral.

But if you do not have 277 volts as your source voltage, connecting

a 277 volt light (usually a ballast) to 120 volt will not work.

Conversely, if you hook up a 120 volt light or appliance to 277

volts, it will quickly become toast.
