natural plasma- sunlight, artificial plasma- tube light
"Natural light" typically refers to light that originates in the sun. "Artificial light" typically refers to light that originates in human-made devices.
The difference between natural and artificial sources of light is that natural sources are produced by the sun while artificial light sources illuminate using energy from other sources and include incandescent bulbs.

Artificial light is not always as good as natural sunlight. There are a few types of natural sunlight bulbs that come close, only they are still missing several wavelengths that are found in natural light. These wavelengths are necessary for plant growth and vitamin D production in animals.
Depends what the source was, for example, if it was started by lightning, it is natural; if it was started by a person, it is artificial. hi! -Andrew

Candlelight is man-made, so is artificial. Sunlight is natural light from the Sun.
Why are artificial lights bad for you? The reason. They are strictly not natural.
