there was lots of talk lately about full spectrum light bulbs. These are light bulbs which cover the entire light wavelength from infrared to near-ultraviolet. Natural daylight is said to be full range light even though we can find variation in the sort of light reaching numerous parts of the earth. When the term is used to refer to light bulbs it is more of a selling label than a scientific term.
To be considered full spectrum light wants to register 90 or higher on the Color Rendering Index or 5000K on the Kelvin Color Temperature rating. Full range lights are regularly employed in situations where you want superior color rendering or don’t have satisfactory access to natural light. Artists will quite regularly employ full spectrum lighting so that their art will look the same in their studio as it’ll when hung in a studio. Paint stores will infrequently use full spectrum lighting to help with color matching if there is not enough natural daylight available.
Full spectrum light bulbs are also thought to help with a spread of health concerns. One reason folk have for choosing full range light bulbs is help with symptoms of Seasonal Affective Disorder. This is a depression many folks experience during the winter months when there is less access to natural sunlight. Many doctors have related that full spectrum light bulbs are a way to help regulate your natural circadian cycles and help with Seasonal Affective Disorder.
Many companies have conducted studies to prove the efficacy of full range light bulbs. To date there has not been any decisive explanation that a full spectrum light bulb is any better at dealing with health issues than other types of light bulbs. There is , however , heaps of apocryphal evidence of people who feel better when they employ it.
