I have several emergency lights over the stairs etc, which light up when
the mains fails.

But if they only last 4 hours, and the power trips when i'm asleep at
midnight, and fire breaks out at 6 a.m. or i need to get up, they will
be flat.

So recommendations for emergency lights with longer lasting batteries
please?

Alter them so they only come on when the circuit is switched on. Just like
a normal light. Unless you leave lights on 24/7.
