This is a list of sources of light. Light sources 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 comes from them.

Incandescence

Incandescence is the emission of light from a hot body as a result of its temperature.
