Can I turn on the desk lamp when it thunders?
If eight miles (4 kilometers) have very high buildings, or within one kilometer than you high buildings, so why why you change PS: if you live in the building is not to worry about it, because the buildings are not the lightning protection system, the state is not allowed to its commercial.
Usually do not have to turn off the lights, as the voltage increases, while the work of the substation is suspended, that is, the power failure, so even if the lights do not close the home will automatically power-off, it is safe.
You'd better not turn on the light when it thunders.In theory, it is safest to turn on the light, but when it thunders, the voltage varies suddenly, causing the light to go off and cause a fire.
