Lights in your room

Living rooms are used for many different purposes and having the appropriate living room lighting is very important. Some rooms used purely for entertaining, others for watching television and many for a whole host of other activities. It's important to have appropriate living room lighting that not only looks great in the space, but also accommodates all of the events that take place there.
Table Lamps
Table lamps are important for providing task lighting. It's a good idea to have a few scattered throughout the room. For a formal look place a pair of matching lamps at either end of a console table or on end tables. If you don't like things to be quite so symmetrical it's perfectly fine to split up a pair and use them in different spots in the room, and if you prefer a less pulled together look use lamps that don't match.
Floor Lamps
Floor lamps are great for adding light where there's no table surface (they're often used in corners). They don't take up very much space and are great for distributing light in awkward spaces.
Wall Sconces
Wall sconces are great for adding a little ambient light to the living room. They look lovely when placed on either side of a mirror or piece of art and act as terrific decorative accents. That said, when it comes to providing light they likely won't be enough. You'll want to use other sources of light as well.
Hanging Fixtures
Chandeliers and pendent lamps can be a fun decorative touch in living rooms. They provide a nice overall glow to the space and draw the eye upward. What's great about them is that they tend to be unexpected in living rooms and can add some real depth. Just make sure that your ceilings are high enough (about 9') so that no one hits their head.
