A floor lamp is the one light in a room that can be moved, which makes it the piece that fixes the problems the ceiling cannot: a dark corner, a reading chair, a wall that needs lifting in the evening.
Taller pieces with an upward or diffused light work as ambient light for the whole room; those with a shade or a directed source belong beside a chair. Several here are the floor versions of families that also come as pendants and wall lights, so a scheme can stay in one language.
