Just found a great product at Costco. It's a rechargable LED
flashlight with a charger base that plugs into a wall outlet. With
the flashlight on the base, it also serves as an emergency light.
When the AC is lost, the flashlight comes on. You can use the LED
flashlight as a regular flashlight when it' off the base. In
addition, the base has an LED nightlight that you can turn off, or on,
or have it on auto so it comes on when it's dark.
I had a similar unit 15 years ago that used conventional bulbs, no
night light. This one is 1/3 the size. You get two of them for $20
