To fight light pollution
Light emitting diodes (LEDs) produce a whiter light than traditional lighting. The LED white spectrum has a significant blue component. Since blue light tends to diffuse in the atmosphere, choosing good quality LED outdoor lighting is key for reducing light pollution.
To avoid health issues
Humans, animals, and plants are being exposed more and more to artificial light, leading to a loss of four to seven hours of rest per day. The blue waves in light prevent the secretion of melatonin, keeping us awake and throwing off our circadian rhythm or biological clock. Melatonin is a hormone that serves several purposes—combating aging, acting as an antioxidant, promoting sleep, regulating blood pressure, and increasing sex drive.
Tests have shown that the negative effects of being overly exposed to the blue waves in artificial light include fatigue, depression, and hormonal cancer. Since LEDs have a significant blue wave component, there is some concern that they increase disease, disorient animals, contribute to the disappearance of insects, and disturb the balance in ecosystems.
Lekla has therefore developed an optical filter that eliminates blue waves and infrared light while maintaining the quality and efficiency of its lighting systems.
