Different Color Wood Floors Next To Each Other – Full spectrum light is light that covers all wavelengths from infrared to near-ultraviolet. Despite the variations in spectral distributions of sunrays reaching different areas of the planet. But when used in relation to electrical lights, It is more of a marketing term so that even products not recognized as complete spectrum may not differ considerably from the ones recognized as such.
Light is deemed complete spectrum once 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’re used by artists who work in studios during the night or in areas where there’s no access to north sunshine.
The use of these special lights aids the artist be certain the colors look as they will when the works are displayed in a house or an art gallery. They’re also used by scientists or to get color-matching in paint stores where north sunshine is unavailable.
In medicine, full-spectrum lamps are used in the treatment of SAD,(Seasonal Affective Disorder), by use of “light boxes” which mimic sunlight during winter. Doctors have proven that this light is a pure stimulus for regulating circadian cycles.
Attempts have been made to independently confirm the efficacy of using full spectrum light in a variety of places. Their study findings do not find full spectrum lighting to maintain any benefits over other light systems
