Despite the variations in spectral distributions of sunrays reaching different parts of the Earth. But when used in relation to electric lights, It is more of a marketing term so that even products not recognized as full spectrum may not differ substantially from the ones recognized as such.
Light is considered full spectrum when it meets the measurements of 90 or higher on a Color Rendering Index,(CRI), or 5000 K on Kelvin Color Temperature ratings. These lights are used a lot in art. They are used by artists who work in studios at night or in places where there is no access to north sunlight.
Use of these special lights helps the artist make sure that the colors appear as they will when the works are displayed in a home or an art gallery. They are also used by scientists or for color-matching in paint stores where north sunlight is unavailable.

In medicine, full-spectrum lamps are used in treatment of SAD,(Seasonal Affective Disorder), by use of ''light boxes'' which mimic sunlight during winter. Doctors have recognized that light is a natural stimulus for regulating circadian cycles.
Attempts have been made to independently verify the efficacy of using full spectrum light in various places. Utility companies, government agencies and experts have come together under the umbrella of the National Lighting Product Information Program (NLPIP), to conduct this research. Their research findings do not find full spectrum lighting to hold any advantages over other lighting systems
