1- You can add table lamps to a side or bedside table. They are often used to read comfortably in bed or simply to provide additional light in a specific area. The fact that they plug directly into the wall makes them very practical.
2- Floor lamps are often used to supplement a lack of lighting in an area where general lighting is less efficient. Just like table lamps, they are connected directly to a wall outlet.
3- You can also use wall sconces where extra light would be useful, on either side of the bed for example. There is no rule of thumb for installing wall sconces in a bedroom. Everything depends on usage and how you want to light your environment.
