With standing structures, there is much more room for uniqueness. They have a large base upon which there is plenty of room to decorate. They also leave room on tabletops so that the decorator has more surfaces to work with for picture frames and trinkets. There is also not the burden of worrying if a table is sturdy enough to support the decoration.
Ceiling light fixtures are great for starters, but when it comes to setting a specific ambiance, they do not quite do the trick. They leave unwanted dark corners and unflattering shades on decorations. Table fixtures with shades are still popular, but overall, they are quite impractical. A floor lamp is easier to clean, has a better throw of light, and casts the most flattering shadows for the room.
