What is “DarkSky Approved”?

When it comes to landscape lighting, homeowners often prioritize aesthetics and security. However, another crucial aspect to consider is the impact of outdoor lighting on the night sky and the surrounding environment. This is where the term “DarkSky Approved” comes into play. But what exactly does it mean, and why should you care about it when planning your landscape lighting?

What is DarkSky Approved? Understanding Light Pollution

Before exploring the meaning of “DarkSky Approved,” it’s important to first grasp the concept of light pollution. Light pollution happens when artificial lighting, such as streetlights, outdoor security lights, and landscape lighting, spreads into the sky, diminishing natural darkness. This excessive, poorly directed, or intrusive artificial light disrupts ecosystems, negatively impacts wildlife, and reduces the ability to appreciate the night sky’s beauty.

Light pollution is not just an aesthetic issue; it can also have real consequences on human health, wildlife behavior, and energy consumption. For instance, nocturnal animals, which rely on darkness to hunt or avoid predators, can be disoriented by excessive lighting. Humans, too, are affected, as improper lighting can disrupt our circadian rhythms, potentially leading to sleep disorders.

The Role of the International Dark-Sky Association (IDA)

The International Dark-Sky Association (IDA) is a nonprofit organization dedicated to preserving the night skies and reducing light pollution. The IDA works with communities, municipalities, and manufacturers to promote responsible outdoor lighting practices. One of the ways they do this is through the “DarkSky Approved” certification.

What Does “DarkSky Approved” Mean for Lighting?

“DarkSky Approved” is a certification given by the IDA to outdoor lighting fixtures that meet specific criteria designed to minimize light pollution. These fixtures are designed to reduce glare, light trespass, and skyglow while providing the necessary illumination for safety and visibility.

For a lighting fixture to be “DarkSky Approved,” it must meet several key requirements:

• Full cutoff design: The fixture must have a full cutoff design, meaning it directs light downward rather than allowing it to spill upwards or outwards. This helps to reduce the amount of light that escapes into the sky.
• Shielding: The fixture should have adequate shielding to prevent light from trespassing onto neighboring properties or into the eyes of passersby.
• Appropriate brightness: The fixture should not be excessively bright. Overly bright lights can cause glare and contribute to light pollution, so the IDA sets limits on the amount of light a fixture can emit.
• Color temperature: The fixture should emit light with a color temperature of 3000K or lower. Warmer light colors are less disruptive to the night environment than cooler, blue-white light.

Why Choose DarkSky Approved Lighting?

Choosing “DarkSky Approved” lighting for your landscape not only helps protect the night sky but also ensures that your outdoor spaces are illuminated in a way that is both functional and environmentally responsible. These fixtures can enhance the beauty of your property without contributing to light pollution, allowing you to enjoy your landscape while being a good steward of the environment.
