Although lighting design is an entirely separate though obviously related field to Interior Design, it often receives scant attention when, clearly, it should be high on the list of design priorities. Here you will find a few general concepts, areas to avoid, and solutions to effectively light the home.

The basics: Yes, I realize, that I have already made my point that lighting plays a critical role in the overall impact of a design scheme, but did I mention that it can also have either a positive or negative effect on energy, emotion and comfort? For many Lighting Designers the goal of planning a lighting scheme is to allow appropriate and effective levels of natural lighting while disbursing multiple types of sources throughout the space. In consideration are the overall effects, task requirements, quality and color of light, and the direction of natural lighting throughout the day-light hours. We all know that beauty under candlelight is simply enhanced, but how about a gold lined shade? These details matter and according to lighting designer, Barbara Cosgrove, "sitting near the right proportioned shade with a gold lining can make the person's skin it look positively radient!" (I have personally noticed the difference and am converting all of my shades at this time!)  Shades also do not all need to be the same color, height or size. In fact, that should be avoided and variation here, is actually key to creating more interesting effects. Also, "everyone should have a lamp with a black shade, but many avoid it. In my mind it is like the little black dress," according to Ms. Cosgrove.

Keep in mind, the goal for almost every room should be to apply direct, indirect and accent or spot lighting, but first consider the source. Different bulbs (lamps) cast different qualities and colors of light. Whereas incandescent bulbs create a yellow and warm cast, halogen creates cooler, whiter and sparkling effects. Frosted bulbs create less shadow lines while smaller bulbs create more. Natural lighting is more cool and blue when north facing and warm towards south facing walls. Fluorescent's are blue and will make you look blue too. Since there is a  fairly wide variety of bulbs it may be necessary to buy a bunch in different strengths and flavors and simply try them out for effect. Since each room functions differently, apply the following requirements:

1. Provide enough outlets in all the right places
2. Determine the main source of light, it's appropriateness and style
3. Light up dark corners
4. Provide task lighting for work-related applications
5. Avoid glaring examples
6. Integrate dimmers on entrance switches for more control
7. Add a little dramatic lighting for high impact

A basic rule of thumb is that if one lamp in a room is providing most of the light then more lights are required. An unequal distribution of light can create glare while inefficient levels of lighting will render shadows in the wrong places. In either case, the eyes are strained. Although the room shouldn't be lit up like a bonfire, varying levels of voltage and light sources will have a strong impact on the overall effect. Here are some more considerations:

• Provide wall-washers or up lights to open the space or draw eyes upwards.
• Provide accent lights behind plants or shapely accessory to create good shadow lines.
• Provide attractive and low glare task lighting for work spaces.
• Provide low-voltage, small halogen ceiling lighting in areas where functions are fixed, such as hallways, over kitchen counters, or bathroom sinks.

Usually, if a space is lacking, the lighting plan is a key to the problem.
