I am still fascinated with electricity and all the things it can do. (Yes, I can still stare at a running 60KW generator in total awe for quite a while.) Having a home with toddlers in it pressured me into building redundant lighting in my homestead back in the 80’s. (The kids were not nearly as stressed if the lights managed to stay on during a storm.) I came up with two solutions. First I installed 12V “Grain of wheat” lamps in the ceilings of all the rooms and installed 12V powered wall lights over the fireplace. (Hey they were popular in the 80’s)
(It became unnecessary to have a flashlight since every room in the house was always Illuminated.) The charger and deep cycle batteries were in the garage with a heavy gauge wire run to a closet DC distribution box.
When “Puck” LED lights became popular in the 90’s I changed out the incandescent grain of wheat lamps out with LED ones. They are quite flat and about 3″ in diameter.
They produced considerably more light and consumed much less power.
The third generation LED lights I installed had a motion sensor in them. Normally the motion sensor would illuminate the unit for a minute or two. I soldered a resistor across the switch so that the LED always glowed and would brighten considerably when the motion sensor was activated. I installed these modified units in the dark areas of the house. (Bathrooms with no windows and closets) Further I powered them with a separate 4.5VDC power supply+Battery replenished with a solar panel permanently installed on the roof.
