which verb with "light" and "electricity"?

[dilodi83]

Are these two possible? Do they mean the same?

1) the electricity/lights went off at 8:30 last night.
2) the electricity/lights went out at 8:30 last night.

Is there a concrete difference between these two phrasal verbs in this context?
Thanks so much for your help.

I would say that the lights went out when the electricity went off.

Is that concrete enough for you?

:up: There are several other meanings for 'go off'; cheese can go off, and fireworks can go off...;-) But I wouldn't say 'the lights went off' - although I'd say they were off, or they were switched/turned off.
