What stair lighting?
And what kind of lighting for the stairs and the hall? I saw a lot of possibilities and it's hard to decide. And you have to plan the installation somehow because there are many luminaires for different voltage and it's hard for me to comprehend it. What is fashionable and what to avoid?
I suggest lighting the stairs and lighting the hall with LED strips. They are easy to use, because they have adhesive tape on the back for easy installation. Profiles can help us install the LED strips. They come in such shapes, which cover the LED light source itself, directing them at the exposed object. You can also use LED luminaires, which we can build into the wall.
