Ours go off at midnight/earlier if they forgot to change it for daylight savings, never seems to have caused a problem.
I prefer it, much easier to sleep without orange light blaring through your window, if for some reason I do want to go out at night I make sure I'm wearing something light coloured I can be seen in and use a separate torch or the one on my phone, though to be honest my lights adjust quickly enough anyway.
Makes no sense having a tonne of lights on that aren't being used at all 90% of the time in those hours, saves the planet and lets you see more stars!
