Fullspectrum

Full spectrum is a term used across disciplines to describe a range that includes the majority of wavelengths or components within a domain. It typically implies capturing or presenting the widest practical combination of elements, rather than a selective subset.

In lighting and color science, full-spectrum light spans a broad range of wavelengths in the visible spectrum, and sometimes beyond. It is used to approximate natural daylight and to improve color rendering. Lamps marketed as full-spectrum aim to produce a more even distribution of wavelengths and higher color rendition indices.

In cannabis and nutraceutical products, full-spectrum formulations contain a broad array of cannabinoids, terpenes, and other plant compounds in addition to the primary active ingredient. They are contrasted with isolates or broad-spectrum products that exclude certain components. Proponents cite the entourage effect, though research in this area is ongoing.

In photography, film, and displays, full spectrum can refer to sensors, films, or displays that respond across nearly the entire visible range, enabling broader color reproduction. It is often used in marketing to indicate superior color accuracy relative to narrow-spectrum options.

The term’s usage varies by field and there is no universal standard for what constitutes “full spectrum.” Definitions typically depend on practical considerations, industry norms, and regulatory context.
