just enough light to prevent tripping over things post eye adjustment would be ideal. If you don't mind going old-school, I picked up a five-pack of directional nightlights at the local hardware store for $20. They plug into an outlet, only turn on when it's dark, and swivel so you can aim the beam at the tripping hazard of your choice. I also put one in the bathroom outlet over the cat's litter box, to help her out. It's just a tiny light bulb and a photodiode, so it's super simple, ultra-reliable, and completely unhackable.
