A living room reads best with light at more than one height. A single overhead fixture leaves corners dark and makes the room feel flat after sunset.
Use a ceiling light or a floor lamp for the general layer. Add table lamps beside seating for reading and conversation. Wall lights can frame a sofa, fireplace, or console without taking surface space.
Match the finish in one or two metals rather than mixing every option in the room. Glass and linen shades give a softer pool of light; metal shades direct light more narrowly. Put dimmable lamps on the circuits used in the evening when the specification says the lamp is dimmable.
Walk the room at night before deciding the final pair. The goal is enough light to read in a chair and a lower level for the rest of the room.
