The reflector had found favor where the choices of artificial light provided poor illumination compared to modern electric lighting. Light shelves are an effective way to enhance the lighting from windows on the equator-facing side of a structure, this effect being obtained by placing a white or reflective metal light shelf outside the window.

The main source of natural light on Earth is the Sun. Historically, another important source of light for humans has been fire, from ancient campfires to modern kerosene lamps. With the development of electric lights and power systems, electric lighting has effectively replaced firelight.
Lighting or illumination is the deliberate use of light to achieve practical or aesthetic effects. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight.
The northern lights are returning for an appearance over North America Saturday night. The states that will likely see the natural light phenomenon, known as the Aurora Borealis, are Washington ...
This is a list of sources of light, the visible part of the electromagnetic spectrum.Light sources produce photons from another energy source, such as heat, chemical reactions, or conversion of mass or a different frequency of electromagnetic energy, and include light bulbs and stars like the Sun. Reflectors (such as the moon, cat's eyes, and mirrors) do not actually produce the light that ...
These properties make it the natural light of choice in certain styles of architecture, [1] painting [2] and photography. [3] In addition, the cool colour of north light has been studied for its effect on our perception of art in galleries and museums. South of the equator (in the Southern Hemisphere), the same characteristics are seen in south ...
