Lighting Your Home
According to the first podcast, light can make a big difference in the way people feel about their homes. It help them to perform tasks more easily, makes them feel safer and comfortable, and allows to enjoy the home to its full potential.

Light can also add beauty and drama to a room, making small rooms to look open and airy, and large room to 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.

Lighting can really make a difference and it is less expensive than other home decorating or remodeling option.

Lighting Needs
In the second podcast, light should be planned to complement the life style, so the first need is to develop a whole individual lighting plan that suits the individual needs of each family member.

When planning the lightening there must be considered the activities that occur in each room, the atmosphere that the user want to create and the decorative elements he wish to emphasize.

Light can be absorbed o wasted in dark colored rooms, or reflected and used as additional illumination in light colored rooms. Also is important to take notes of those areas serving more than a single purpose. Those areas require more than one type of lighting.

Fundamentals of Lighting
There are three basic types of lighting that work together to light the home: general, task and accent. A good lighting plan combines the three types to light an area according to function and style.

General lighting provides an area with overall illumination. It is also known as ambient lighting. It radiates a comfortable level of brightness and enables one to see and walk around safely. It can be accomplished with chandeliers, ceiling or wall mounted fixtures, recessed or track lights. And with launders outside the home, a basic form of lighting that replace the sunlight, general lighting is fundamental to a lighting plan.

Task lighting helps the user to perform specific tasks such as reading, sewing, cooking, homework, or games. It can be provided by recess or track lighting, pending lighting and portable lamps. Task lighting should be free of distracting shadows and should be bright enough to prevent eye strain.

Accent lighting adds drama to a room by creating visual interest. As part of a decorating skin, it is used to spot light paintings, sculptures and other precious possessions, to highlight the texture of a wall, drywall or outdoor landscaping. Accent light requires at least three times as much light at the focal point as the general light around it. This usually is provided by track, recess, or wall mounted fixtures.

=Interest Facts About Light=

**Light Spectrum**
 * Light waves of a specific energy level will emit a particular color.
 * Sir Isaac Newton recognized the visible light spectrum in 1666, and he identified seven colors: red, orange, yellow, green, blue, indigo, and violet.
 * Newton’s colors are arbitrary segments of the continuous spectrum of color.
 * When all of the spectral colors travel together, they combine to make white light.

The Speed of Light

 * Transparent materials cause light to refract, or bend its path, because light travels at different speeds in different mediums, like water or glass.
 * The speed depends on the composition and density of the medium, how many atoms are getting in the way.
 * The reduction in speed causes light to bend upon entry into that medium. Since different wavelengths of light bend at different angles, certain materials can act as prisms, causing white light to visibly split apart into its spectrum.

The Properties of Light

 * Light can also reflect, or bounce, off objects. This is what causes us to see.
 * Light rays emitted from a light source reflect off objects in all directions and transmit the image of that object to your eye.
 * Objects with very smooth surfaces, like mirrors, reflect light so well that they redirect it in a single direction.
