This is a list of sources of light, including both natural and artificial sources, and processes and devices that emit light. In this list, light is considered to be electromagnetic radiation that is visible to the human eye, and not blackbody radiation in the more general sense. The list is also limited to sources of light, as opposed to objects such as the Moon that provide light by reflection.
