Like paint, lighting can dramatically change the feeling of a room. And you probably don't want to elicit the same feelings in every room of your home. Want to create a cozy space? Add lots of reading lamps to the room, and wall sconces or torchieres, which create a warm glow. A fireplace always elicits a comforting feeling, too. To encourage an energetic mood, you want to couple bright ambient lighting with very focused task lighting. Recessed strip lighting, for example, is great in the combination desk-bookcase units popular for home offices. And multi-bulb fixtures make an entire room brighter, allowing you to easily see detail, whether in a cake you're decorating or a miniature railroad you're assembling. Need a romantic hideaway? Nix overhead lights in lieu of several small lamps with warm or dark-colored shades. If you add sconces, place them lower on your wall than normal; this will make the ceiling look lower and the room cozier. And don't forget those all-important dimmer switches [source: GE Lighting].
