Ida’s fixture seal of approval program certifies outdoor lighting as being dark sky friendly, meaning that they minimize glare while reducing light trespass and skyglow. All products approved in the program need to be fully shielded and have less blue light in their output.
“We are pleased to announce that we have been approved by the U.S. Environmental Protection Agency (EPA) for the use of LED lighting in our outdoor light fixtures,” said Michael J. O’Brien, President and Chief Executive Officer of the National Park Service.

What does it mean to be dark sky compliant?
When an outdoor lighting fixture passes the ida fixture seal of approval program, it is called dark sky compliance. Association is the voice for light pollution. They educate designers, manufacturers, committees and the public about controlling the use of artificial light in the night sky. For example, some people thought that if a light was on 24 hours a day, it would be a violation, but that is not the case.
In fact, if the light is on for more than 12 hours in a 24-hour period, then it is considered a non-light-pollution violation and will not be reported to the National Park Service (NPS) or the Federal Aviation Administration (FAA).
FAA are responsible for enforcing the Light Pollution Control Act (LPCA), which is a federal law that regulates the amount of light that can be emitted from buildings, structures, vehicles, and other sources in order to reduce the number of stars and constellations that are visible from the Earth’s surface.
Why is Dark Sky important?
Without artificial light, a night sky is vital to the proper functioning of natural ecosystems. Some of the consequences of artificial lighting include species migration patterns, predator-prey relationships, and the rhythms of many organisms. The effects of artificial lighting are not limited to humans, however. A recent study published in the journal Nature Climate Change found that the amount of light emitted by a city’s streetlights can have a significant impact on the health of its residents.
The study, conducted by researchers from the University of California, San Diego, looked at the effect that light pollution has on people’s health, as well as their exposure to harmful ultraviolet (UV) radiation, which can lead to skin cancer and other health problems. States alone, more than 1.5 million people die each year as a result of indoor air pollution, according to a recent report by the American Lung Association.
Are string lights dark sky compliant?
String lights may be allowed in occupied dining and entertainment areas only and must not exceed three thousand (3,000) Kelvin. Landscape lights will not be used with string lights. This doesn’t apply to seasonal or special event lighting.
The lighting requirements for dining areas shall be as follows: (a) All dining area lighting shall comply with the requirements of Section 6.5. (b) The maximum number of string lights permitted in an entertainment area is one (1). (c) A minimum of two (2) string light fixtures shall illuminate the interior of each seating area, except that a maximum of four (4) strings may illuminate an area of up to two hundred (200) square feet (100 square meters) in area.
Each string lighting fixture shall have a minimum height of twenty-four (24) inches (610 mm) above the floor, and shall extend at least six (6) feet beyond the edge of the area to which it is attached to the ceiling or floor. A string lamp may not illuminate more than one area at a time. All string lamps must be of a type approved by the Department of Building Inspection.
Are gas lanterns dark sky compliant?
The lighting open flame burners do not emit enough light. The open flame burner is suitable for areas that recognize “dark sky” ordinances as it is not visible to the unaided eye.
“Lighting‖ ”open flame‗ is a type of light source that is used to illuminate the night sky. Open flame ‖breathes out light in the form of a flame that can be seen with the naked eye, but is difficult to see in low light conditions, such as at night, or when the sky is obscured by clouds, fog, smoke, haze or other obscuring objects.
Do LED lights cause light pollution?
It’s hard to stargaze because of light pollution, particularly the blue light emitted by led bulbs. It can cause serious consequences for wildlife, whose biological rhythms and nocturnal instincts are disrupted when they are near artificial light.

Is it important to save dark skies?
Reducing light pollution can result in a decrease in energy consumption. Improvements to lighting design, technologies, and efficiency can conserve energy and reduce the amount of light that reaches the Earth’s surface. Visibility is one of the most important factors in determining the quality of a night sky. If you can’t see the stars, you won’t be able to appreciate the beauty of our night skies.
In addition to improving visibility, improving lighting can help you see more stars and constellations. For example, a brighter sky can make it easier for you to spot the Milky Way, the Andromeda Galaxy, or the Pleiades, all of which are among the best-known and most-studied stars in our galaxy.
What causes sky glow?
The sun’s light is the most important source of light in our sky, but it is not the only source. The moon, planets, stars and other celestial bodies also emit light. In addition, sunlight is scattered and absorbed by clouds, snow, ice, rain, fog, smoke, dust and so on.
What is wildlife friendly lighting?
Wildlife lighting from access fixtures uses leds that emit light in a wavelength safe for wildlife in coastal areas, roads, walkways, and parking lots. The effect of light pollution on wildlife is mitigated by the use of these light fixture.
