The first is to use light fixtures that are capped. The most important feature of any approved light fixture is its ability to shield light from escaping upward and outward beyond its intended target. ![]() They have a great infographic that demonstrates “acceptable” versus “acceptable” light fixtures. The International Dark-Sky Association is the global leader in light pollution awareness. Light pollution can be greatly curtailed by using the right kind of light fixtures. Light Fixtures That Decrease Light Pollution By altering the appearance of light, human physiology is altered, resulting in sleep disruptions, increased stress, and other physical and psychological maladies. Like most other living things, humans function on a 24-hour natural cycle that is closely tied to the changing light of dawn, midday, dusk, and night. Depriving these species of darkness can alter their life cycles and reproduction. Many animals also use the nighttime for breeding rituals. By turning night into day, the food chain is drastically altered. Both predators and prey use darkness to their advantage, avoiding detection as they hunt or hide. Nocturnal animals are the most drastically affected. Light pollution also creates giant islands of light that disrupt wildlife and entire ecosystems. All that extra light translates into billions of watts of wasted electricity and tons of carbon emissions. First of all, light pollution is defined as light that is excessive or escapes its area of intended use. In addition to the aesthetic effect of losing the night sky, light pollution has a serious impact on the environment. If you look up at night and don’t see a sky full of brightly shining stars, you live in a bubble of light pollution. Unfortunately, as human populations spread and industrialize, light pollution has grown. When light pollution is bad enough, it can change the color contrast of the night sky, eclipse natural starlight, and disrupt the circadian rhythm (natural 24-hour cycle) of humans and wildlife. It is the result of interior and exterior lighting in populated areas. ![]() Light pollution is the excessive, invasive, or misdirected use our artificial lighting. If you’ve ever noticed the difference between looking at the night sky in a city and deep in the country, you’ve seen the effects of light pollution. At Night Vision Outdoor Lighting, we take light pollution seriously and always design to reduce light pollution from outdoor lighting. ![]() But that doesn’t mean that it should be ignored. Light pollution just doesn’t get the same press as other types of pollution, and in most places, it is still entirely unregulated. But one source of pollution has only recently begun to be acknowledged. Better insulation, double-paned windows, and more efficient heating and cooling systems make keeping cozy more environmentally friendly. Energy-efficient appliances and lighting options, like CFLs and LEDs, have become the norm. New technologies have also made it easier to reduce our carbon footprint. Responsible homeowners make sure to separate out their glass, plastic, paper, and metal to keep it out of landfills. Of course, many municipalities have made recycling available for decades. Consumers are becoming more and more environmentally conscious.
