This is a list of sources of light, including both natural and artificial sources, and both processes and devices.
A typical "light source" emits electromagnetic radiation in the visible spectrum. The list is oriented towards visible light: nearly nothing emits photons through blackbody radiation. See also List of reflected light sources
