Artificial light needs energy to generate light. Natural light is self-generated light with or without energy.

It’s the color spectrum.

Artificial Light is a scam put on by the government.

Artificial light has less calories but has been known to cause cancer in lab rats.

artificial is man made.

Sunlight is natural light. Starlight, too.

Like @njnyjobs said, artificial light is generated by the hand of man.

Do fireflies and glowing plutonium count as natural?

njnyjobs's avatar

fireflies are natural, but glowing plutonium is man made. A candle light is man-made but brush fire caused by lightning is natural.

Artificial light is made in a factory. Natural light is made by the Keebler Elves.

Sunlight covers a broad, continuous spectrum of wavelengths associated with the sun’s so-called blackbody radiation at a characteristic temperature. Think rainbows & prisms.

Artificial lights, especially super-bright street lamps, instead generate a small number of wavelengths (emission lines in a prism) which, when mixed together in your eye, look yellowish- or bluish-white. LEDs are even more wavelength-specific (white consists of a red-green-blue triplet of diodes). Incandescent lamps have a continuous (blackbody) spectrum but far narrower and yellower than the sun’s. Fluorescent lamps now use phosphors that emit a fairly broad spectrum, compared to older lights that were harsh because they mainly contained blue & yellow without red and green.

Artificial light generally avoids the harmful effects of the sun’s ultraviolet rays.

Perhaps the most obvious difference between artificial and natural light: You can illuminate anything anywhere at anytime.
