Commercial codes have required emergency lighting for decades. I've
added a couple of inexpensive ones at home.

First one I bought is an Energizer from Tractor Supply. Plugs into
any socket and maintains a charge. If power goes out, light goes on.
Yesterday I was in Home Dept and bought a $10 Capstone Eco i Lite that
does the same thing and has a night light. What is nifty is it has an
induction charger so no contacts to make when taking it out or putting
it back in the holder. Charge is supposed to last 4 hours.

Of course, I have other flashlights and an LED lantern, but if the
power goes out suddenly, we won't be in total darkness trying to find
a light.

If the power goes out here there is plenty of light from the monitors
and LEDs on all the computers in the office on UPS. There are
flashlights in most rooms anyway so you don't have to look far for one.
