This bedroom uses different sources of lighting. The under-cabinet lighting in the display cabinets provides accent lighting for showcased objects. The ceiling fixture adds a decorative touch.

ATLANTA — Since relocating from California to Atlanta for her husband's job, Marty Webb has made plenty of changes to her home — with lighting options never far from her mind.

Over the past two years, the six-bedroom house in Buckhead, Ga., has been painted, and several bathrooms have been renovated. Along the way, Webb has shopped for decorative lighting fixtures for various rooms.

Webb's hunt for a ceiling fixture for her bedroom sitting room took her to a boutique. There, she found the “perfect” hanging fixture with a silver leaf finish. On another visit, Webb spotted a floor lamp for the same sitting area.

She bought a more ornate chandelier for her master bathroom — but chose a “fun” one for another upstairs bathroom. Recently, Webb found an antiqued mirrored sconce to light the stairway in her home. She bought three.

“Lighting is an easy and relatively inexpensive way to update a room,” Webb said.

The right lighting does more than illuminate. It allows you to perform a variety of activities in each room. A fixture, such as a chandelier in the bedroom or bath, also adds drama or a pop of color to a room.

But before you shop for lighting fixtures, do some homework and consider these tips from the American Lighting Association, a Dallas-based trade group.

Identify the activities that occur in each room. Consider food preparation, grooming, reading and homework.Identify which rooms will serve more than a single purpose. Those areas will need more than one type of lighting.Identify the mood or ambience that you want to create. Keep in mind that dark colors absorb more light. You may need to provide additional light in rooms with dark wall colors.Consider your style. You want the lighting's shape, color and size to complement the room and your home's style.

A good lighting plan involves three types of lighting: ambient or general lighting, task and accent.Ambient lighting provides the room's overall illumination. It allows you to see and walk around safely. It can include chandeliers, ceiling or wall-mounted fixtures. Ambient lighting also can include recessed or track lighting. Have a central source of ambient lighting in all rooms.Consider adding dimmers, which some designers consider a must-have update, especially in the kitchen. Dimmers allow you to adjust the intensity of the light or to strike the right mood.Task lighting helps you perform specific tasks, such as preparing food or reading. Task lighting includes pendants, floor and desk lamps and under-cabinet lights.Accent lighting creates visual interest in a room. It can be used to focus on a painting or sculpture or highlight a wall. Track, recessed and wall-mounted fixtures provide accent lighting.

Lighting can go on the ceiling or on a wall or table. If you prefer light from above, your options include chandeliers, flush-mount fixtures, pendant lights, track and recessed lighting. A combination will give you the light you need for general lighting and tasks.Wall lighting provides indirect light and adds a decorative touch. Wall-mounted fixtures, or sconces, light a wall area and can be used in most rooms. For a functional reading lamp near a bed or sofa, swing-arm lamps are popular.Floor, desk and table lamps allow you to place your lighting where it is most needed.
