This is a list of sources of light, including both natural and artificial sources, and processes and devices which emit light. The list is oriented towards visible light: most things emit photons through blackbody radiation. Light as in electromagnetic radiation that is visible to the human eye. Its nominally limited to sources of light, as opposed to reflected light but again, most light sources undergo either refraction or reflection before observation. This is a highly generic list, combining light sources from standpoint of human observation, like a light fixture, with specialized physical definitions from the fields of chemistry and physics.
