DISCUSSIONS:

Lighting or illumination is the deliberate use of light to achieve a practical or aesthetic

effect. Lighting includes the use of both artificial light sources like lamps and light fixtures, as

well as natural illumination by capturing daylight. Day lighting $($using windows, skylights, or light

shelves$)$ is sometimes used as the main source of light during daytime in buildings. This can

save energy in place of using artificial lighting, which represents a major component of energy

consumption in buildings. Proper lighting can enhance task performance, improve the

appearance of an area, or have positive psychological effects on occupants.

Indoor lighting is usually accomplished using light fixtures, and is a key part of interior design.

Lighting can also be an intrinsic component of landscape projects.Table $6\mathrm{.}1$ Reflectances of Typical Paint and Wood Finishes
