The report discusses the benefits of natural light over artificial light. Natural light has positive effects on human health like improving sleep and reducing depression. It also benefits plant growth and allows for inexpensive natural-light photography. Daylight is sometimes used as the primary light source in buildings to reduce energy consumption from artificial lighting. Proper lighting, whether natural or artificial, can enhance performance and well-being.

2. NATURAL LIGHT : Daylight provides a better lighting environment than cool white or
energy-efficient fluorescent
electrical light sources because “daylight…most closely matches the visual response that,
through evolution, humans have come to compare with all other light” (Franta and Anstead
1994). The majority of humans prefer a daylit environment because sunlight consists of a
balanced spectrum of color, with its energy peaking slightly in the blue-green area of the
visible spectrum
USES OF NATURAL LIGHT:
Health Benefits
UV radiation from the sun causes skin cancer, but only in high doses over many years. Small daily doses of natural light help
you sleep, according to Deborah Kotz in a June 2008 article for "US News and World Report." Exposing yourself to natural
light tells your body to stop melatonin production. This prevents daytime drowsiness. Exposure to sunlight also causes the
body to produce more serotonin. Low serotonin production is believed to be a cause of depression. People who suffer
from Seasonal Affective Disorder find relief by using lamps that mimic the spectrum of natural light in the winter, when less
sunlight is available.
Plantation
Plants grow best in natural light, which contains a broad spectrum of
colors. House plants often grow slowly or lose leaves due to inadequate
light. Southern-facing windows provide the most natural light for indoor
plants, says the Texas A&M University Agricultural Extension Office.
Eastern and western-facing Windows may also work, but they only
receive 60 percent of the light a Southern-facing window does.
Fluorescent lights provide the blue spectrum of light most plants use for
leaf production, but are missing the infrared wavelengths of natural light,
which stimulates flowering.

3. Photography
Natural-light photography takes advantage of the abundant sunlight available during the
day. Shooting in natural light prevents the need for expensive artificial light, which can be
difficult to set up. Different conditions, such as cloud cover or a setting sun, change the
color and intensity of natural light.

5. 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.
Daylight (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.
