All About Lighting

Lighting can make a big difference in how you feel about your home. It helps you perform tasks more easily, makes you feel safer and more comfortable, and allows you to enjoy your home to its full potential. Lighting adds beauty and drama to a room. It can make a small room look open and airy, and large rooms appear cozy and inviting. It can create a stimulating atmosphere for a night of entertaining, or a quiet feeling of relaxation after a long, tiring day. In so many ways, lighting can make a difference. And, it does so inexpensively compared to other home decorating or remodeling options.

Determining your needs.

Lighting should be planned to complement your lifestyle. So, first you need to develop a home lighting plan that suits your individual needs and those of your family. When planning your lighting, look at the activities that occur in each room, the atmosphere you want to create and the decorative elements you wish to emphasize. Keep in mind that light can be absorbed and even wasted in dark-colored rooms, or reflected and used as additional illumination in light-colored rooms. Also, take note of those areas serving more than a single purpose and those that will require more than one type of lighting. If you need assistance with your plan, a Certified Lighting Consultant at your local ALA showroom will be happy to help.

The fundamentals.
There are three basic types of lighting that work together to light your home: General, Task and Accent . A good lighting plan combines all three types to light an area, according to function and style

Energy Savings and Efficiency

Lighting uses 12 to 15 percent of the electricity consumed in a home. Suggested ways to economize on electricity bills with lighting are:

1. Turn lights off when you don't need them.

2. Use dimmers to save energy.

3. Use photoelectric cells or timers to turn outdoor lighting on and off automatically.

4. Use the more efficient reflector bulbs, especially for task and accent lighting. (Example: a 50W "R" bulb can put as much light on an object as a 100W "A" bulb.)

5. Use energy-saving fluorescents wherever possible. They give more lumens-per-watt (more light from the electricity consumed) than incandescents. New compact fluorescents produce light that is similar in color to that of incandescents, making them an excellent choice for residential use. They are now available in styles that can accommodate a wide variety of decorative and functional fixtures.

Living Room Light Design

When designing a lighting plan for a living room or family room, you need to consider the variety of activities that occur there. You'll want to include general lighting for entertaining and watching television, task lighting for reading or sewing, and accent lighting for artwork, plants, and interesting architectural features. Dimming controls are ideal for the living room because they allow you to design the lighting to suit each mood and activity.

Fireplaces made of brick or stone can be emphasized with recessed downlights installed in the ceiling over the mantle to create an intriguing grazing effect across the surface. Wall sconces on each side of the fireplace are an attractive addition that draws attention to the fireplace area, while providing general lighting for the living room.
Reading requires task lighting that comes from behind the reader's shoulder. This can be accomplished by placing a floor lamp either at the right or the left of the reading chair. The bottom of the shade should be located at eye level to avoid glare.
Paintings can be highlighted with low-voltage, tungsten-halogen picture lights. These frame-mounted lights spread a beam of bright, white light across the face of the painting.
House plants can be accented by aiming an uplight can at the wall behind the plant, creating a dramatic silhouette of the plant against the wall. .
Bars can be lighted from above with recessed or track fixtures, or with miniature, low-voltage pendants that hover intimately over the bar.
Glass shelves and glassware can be accented by two recessed adjustable fixtures. The use of low-voltage fixtures with tungsten-halogen bulbs will emit a bright white light that will make glassware sparkle, while providing added illumination for serving and cleanup.
TV, video games, and computers require low-level general lighting that does not wash out the screen's image nor reflect into the viewer's eyes. Miniature track lighting can be installed under shelves to provide both general and accent lighting. Choose from accent spots, mini-lights, and compact or linear fluorescent light sources.
Game tables require bright, even overhead lighting. Shaded pendants equipped with either incandescent bulbs or energy-efficient compact fluorescent tubes are one solution. Or, install two recessed downlights over each half of the table.
      

Dining Room Light Design

Dining room lighting should be both beautiful and functional. This requires a mix of general, task, and accent lighting that can set the mood for a number of functions, including a formal dinner, a family get-together, and other activities such as homework, hobbies, or family bookkeeping. Dimming controls will enable you to vary the light for each occasion.


A chandelier is the focal point of the dining room. Suspended over the dining table, it serves as a decorative style element that enhances the beauty of your fine furnishings. When the light is dimmed, a soft, glowing atmosphere similar to candlelight is created. If equipped with a downlight, the chandelier provides task lighting for the table and accent lighting for a centerpiece.
Recessed or track lighting provides general lighting, while enabling you to highlight prized possessions throughout the room. A ring of four recessed downlights around the dining table supplements the light from the chandelier, while providing accent lighting for your tableware. The pure white light of low-voltage fixtures with tungsten-halogen bulbs will make your crystal and silverware sparkle.
A buffet or sideboard can be flanked with wall sconces on either side. Choose fixtures that complement the style of your chandelier. Displayed objects can be accented with recessed downlights installed in the ceiling above.
A family portrait can be dramatically lighted with recessed adjustable accent fixtures. Ask the certified lighting consultants at your local ALA showroom to help you choose fixtures that are best suited for this purpose.
A China cabinet, breakfront, hutch, or wall niche can become a showplace for your prized collectibles by installing strips of low-voltage mini-lights under the shelves.

Kitchen Light Design

A large ceiling fixture, equipped with energy-efficient fluorescent tubes will supply plenty of well-diffused general lighting, but it may leave you working in your own shadow at the sink, range, and countertops. These areas need supplemental task lighting. For example, two track lights over the sink will give you the illumination you need for washing dishes and scouring pots and pans.
At the sink and range, an individual recessed downlight, equipped with an energy-efficient compact fluorescent tube, will provide you with adequate task lighting when installed in the ceiling or in soffits over these two busy work areas.
Dinettes, nooks, and island counters can be lighted with decorative pendants. When used with a dimmer control, these ceiling-hung fixtures will provide you with adequate task lighting for homework, hobbies, or family business and allow you to lower the light for dining or entertaining.
Undercabinet lighting is ideal for countertops. Mount as close to the front of the cabinets as possible to avoid glare reflecting off work surfaces. Choose energy-efficient fluorescent fixtures (they generally range from 12 to 48 inches long) that cover at least two-thirds the length of the counter.
Kitchen cabinets can be accentuated by placing low-voltage mini-lights over, under, or inside cabinets.
Soffits and other concealed locations can also be treated effectively with this type of lighting. These inconspicuous strips of miniature incandescent bulbs will highlight your cabinetry, while adding a warm, comfortable atmosphere to your kitchen.

Bedroom Light Design

When lighting a bedroom, you will want to create an overall atmosphere of quiet relaxation, while providing some bright spots for reading and other activities. A combination of general and task lighting that takes into account the age and lifestyle of the occupant(s) is needed. Remember, dimming controls give you the flexibility to vary the light to suit different moods and activities.


Office Light Design

Two large ceiling fixtures, containing energy-efficient fluorescent tubes, will provide plenty of well-diffused general lighting, while eliminating shadows on the desk. Place the fixtures over head and to the right and left of the desk so the light comes over the shoulder. Lighting placed in front of a desk will cause troublesome reflections.
Credenzas can be illuminated with slim undercabinet fixtures containing energy-efficient fluorescents. Mount as close to the front of the cabinet as possible to avoid glare reflecting off the work surface.
Pictures, mementos, professional certificates, or an attractive plant can be highlighted with track lighting.
An adjustable table lamp will provide additional light to the desk and keyboard areas. Position the lamp so it is not reflected in the computer screen.
