A USB book light It has 3 modes that can all be dimmed, and it fits on the fender of my 700lb harbor freight hand truck, and can clip to various hats.

I've used these quite a few times during power outages. Especially in the bathrooms. You keep them plugged into your lamps or fixtures, and when the power goes out, they'll stay on, or you can take them out and use them with a small attachable hook. I also have a few USB powered ones that I use with some cheap battery packs I got at Walmart by the registers.
A good USB battery pack with fast charge and USB C. Gotta keep your phones charged.
A good folding solar charger to keep those battery packs topped up, with a USB splitter cable.
UCO candle lanterns. Tea lamp and 3 inch. Not the brightest lanterns, but with a tin foil reflector it's enough to read by. Good for when you can't charge the batteries.
