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 comes from them.
