Full-spectrum light

Full-spectrum light is light that covers the electromagnetic spectrum from infrared to near-ultraviolet, or all wavelengths that are useful to plant or animal life; in particular, sunlight is considered full spectrum, even though the solar spectral distribution reaching Earth changes with time of day, latitude, and atmospheric conditions.

"Full-spectrum" is not a technical term when applied to an electrical light bulb but rather a marketing term implying that the product emulates natural light.

Products marketed as "full-spectrum" may produce light throughout the entire spectrum, but actually do not produce an even spectral distribution, and may not even differ substantially from lights not marketed as "full-spectrum".

Measurement

Color temperature and Color Rendering Index (CRI) are the standards for measuring light. There is no technical definition of "full-spectrum" so it cannot be measured. To compare "full-spectrum" sources requires direct comparison of spectral distributions.

Full Spectrum

Full Spectrum is a series of five anthologies of fantasy and science fiction short stories published between 1988 and 1995 by Bantam Spectra. The first anthology was edited by Lou Aronica and Shawna McCarthy; the second by Aronica, McCarthy, Amy Stout, and Pat LoBrutto; the third and fourth by Aronica, Stout, and Betsy Mitchell; and the fifth by Jennifer Hershey, Tom Dupree, and Janna Silverstein.
