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

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?

you probably won't find any. The standard specification for emergency
lights is 3 hours.

yup

that's what ours here are rated for

the PP's scenario is in the realms of fantasy

the use case is that it's the fire that burns out the electrical circuits
that causes the emergency lights to be required
