admin Do you want to light up your deck without lighting up the neighborhood? Then you need to look into low voltage outdoor deck lighting. It is possible to get the security of outdoor lighting without compromising the beauty of the night sky with dark sky lighting.
Dark sky lighting is designed to reduce the glare and light pollution from normal home landscaping. An estimated 30% of all outdoor lighting is wasted, costing Americans millions of dollars each year. Using low voltage outdoor lighting certified by the International Dark Sky association saves you money without sacrificing aesthetic beauty.
The economic dangers of standard outdoor lighting go beyond the waste of money and energy. It effects the wildlife, too. Large amounts of artificial lights have an adverse effect on migratory birds and mating habits of tree frogs. Poor hatchling turtles can be spotted easier by prey when attempting to return to the sea.
Light pollution did not happen overnight, it slowly increased over time. However, with the explosion of suburban homes, light pollution exploded to the point that it is now considered an environmental hazard. The problem has become so bad that 50% of Americans cannot see the Milky Way from their homes. Due to the increasing problem of light pollution, many states have enacted dark sky laws.
Unfortunately, in the past, light pollution was not a high priority. Thankfully, this is changing. With the increasing availability of low voltage outdoor deck lighting and the increasing awareness of light pollution, more and more people are choosing the energy efficient and aesthetically pleasing dark sky lighting fixtures.

Yes, there are many locations where you could find smiler ecosystems one near a source of light pollution and the other far away from it, you could take such a situation and compare the biodiversity, rate of plant growth and animal reproduction in the two locations, as well as many other factors, however there is always the fact that the two locations can not be the same in every aspect (elevation, precipitation, CO2 levels, etc.) so the most accurate way would be to take a set area say 2 acres and divide them up so that one side is subject to light pollution and the other is not, and to see how the sides change from the original survey
