Natural full-spectrum light offers a wide range of benefits for a variety of applications, from industrial facilities to schools and hospitals.
Below are five of the top benefits that full broad-spectrum light can provide.
Increases Sales Figures
Implementing natural lighting into a retail facility has been shown to improve sales. A case study by the California Energy Commission found that, on average, facilities that made use of broad-spectrum natural light had sales numbers up to 6% higher than facilities lit by artificial lighting. Another study, conducted by Walmart discovered that the same product, when displayed under natural light, would consistently outsell an identical item in a non-daylit section of the store.
Enhances Interior Design
Full-spectrum light enhances the appearance of spaces, making them appear larger and more vibrant. Under commonly used fluorescent lamps the human eye is only capable of differentiating about eight shades of each color. On the other hand, under natural light, our eyes can recognize up to 50,000 individual shades. Natural, diffused light also makes spaces appear cleaner and more spacious by eliminating shadows that naturally occur at the corners of a room.
Maintains Nutrients in Food
Research show that foods like leafy, green vegetables respond to the same day-night light cycle as human bodies. When vegetables are stored under artificial light, these plants have a tendency to go bad faster. However, when these plants are stored under full-spectrum natural light during the day they are to last longer and retain metabolites like glucosinolates and chlorophyll, which can have powerful detoxifying and anticancer effects on the body.
Boosts Learning Rates
Artificial light could actually be damaging students’ academic progress. Comparative studies of schools in both Sweden and the United States show that students absorb and process information faster when they receive ample natural light. One study found that students whose schools used natural lighting progressed 20% faster on standardized math tests and 26% faster on reading tests than students who learn under artificial light.
Improves Occupant Health
Exposure to full-spectrum light has long documented benefits. Moderate exposure to sunlight is shown to help improve visual health and aid in the prevention of medical conditions including seasonal affective disorder, pre-diabetes, multiple sclerosis, hypertension, and some autoimmune diseases. Natural light is so beneficial that workplaces who integrate it experience a decrease in employee sick days of up to 6.5%.
While artificial bulbs are getting better at duplicating natural light, currently the only way to ensure consistent full-spectrum light for your facility is by incorporating daylighting into the building design.
