This curated assortment of Dark Sky conforming lighting is designed to minimize light pollution. You can control light pollution by selecting Dark Sky conforming fixtures. Dark Sky fixtures avoid glare, reduce light from spreading and keep the night sky dark. Some coastal areas in Australia and New Zealand also require Dark Sky fixtures (called turtle friendly) to protect the breeding area of sea turtles from artificial light at night… turtles come onshore to lay eggs at night, with hatchings returning to the sea at sunrise.
