Dark sky lighting refers to a style of light that preserves nighttime environments. There is a non-profit organization that has thousands of members in over 70 countries throughout the world that comes up with solutions for outdoor illumination. This group raises awareness and educates the public about the value of maintaining the natural night sky.
This group works alongside companies to create products that have shielded designs and are efficient to direct the light source down where it is needed rather than up where it can contribute to light pollution or sky glow. Community awareness is built in order to affect legislation for the reduction of light pollution. They have an education arm that offers tools to create awareness through brochures, activities, presentation and lesson plans for children.
Working with astronomers, industry professionals, ecologists and communities there is a collective approach to advocate the quality of outdoor lights. Members of the organization receive a subscription to their newsletter, discounts on events, conferences and materials, and opportunities to participate in local chapter activities.
Negative effects in the health of humans, the disruption of wildlife balances and ecological balance, and wasted energy are all light pollution results. It affects night visibility, produces light trespass and clutter, night glow and glare. It adversely effects astronomers and scientists in their work.
Circadian rhythms are good for human health, exposure to artificial light reduces the human body's ability to produce melatonin, a hormone that is responsible for telling the body that it is dark. Artificial light can come from indoor sources or careless outdoor lighting from a neighboring property which is disruptive to sleep patterns.
Astronomers are affected by sky glow and light trespass, to prevent this shielded designs are recommended that direct the light source down to the needed area and deflect it from shining up and out to places it is not needed. When a fixture is pointed upward it contributes to sky glow which accumulates and creates an orange glow over towns and cities interfering with scientific instrumentation.
Ecological imbalances occur when lighting confuses the migration patterns of birds, mating behaviors are interrupted and light from buildings can confuse birds to the point of their dying from exhaustion as they collide into each other. Sea turtles are confused when they see shore lights as they are attracted to the moon to guide them into the oceans, this causes them to encounter predators and walk into roadways. The mating of frogs is disrupted when bright night and stadium lighting is near their habitats. The communication of insects that use bio-luminescence is disrupted by artificial lighting.
