The dark sky movement has grown tremendously in recent years in strength, capabilities, and popularity. It has been our experience that 'dark sky' is now a lighting phrase that is an integral part of almost every exterior project. Not just lighting designers, but more and more architects and engineers have not only heard of the dark sky movement, but are very involved in implementing and advancing the dark sky cause.

As a manufacturer of quality lighting fixtures and as a responsible and socially aware business organization, Selux Corporation recognizes and understands the importance of dark sky, both the International Dark-Sky Association and its goals. We consider it our responsibility to design, develop, and manufacture lighting fixtures that have optics with excellent control. Selux has no less than 10 fixtures in its portfolio that are dark sky certified by the Association.

Today, outdoor lighting design is vitally concerned with dark skies and affecting light pollution issues. Many of the new luminaires are designed and manufactured with full-cut-off optical systems. While these new lighting regulations started in the southwest-Arizona, New Mexico, and Southern California-the movement continues to expand eastward.

Industry standards on luminaire efficiency once were measured by the amount of light luminaires can throw down and the distance by which they can be spread apart. Today, the requirement has become much more sophisticated. Now we address the performance of light as light pollution, cut-off and veiling luminance, and glare.

The main purpose of the dark sky movement is to preserve and protect the nighttime environment through quality outdoor lighting. By eliminating light pollution we are able to find another solution to protect and enhance our environment.

Uniting our environmentally friendly clay lights with the 'dark sky' initiative was a natural collaboration. It makes me feel that in a small way we are making a difference. The International Dark-Sky Association has been supportive and helpful through the certification process.

Dark sky technology is the driving force behind all of our outdoor product development. The dark sky philosophy of directing light only where it is needed forces manufacturers to carefully consider the following:
• maximum reflector efficiencies
• lower-wattage lamp alternatives, such as the new 20W metal halide lamp
• the removal of all unwanted glare and wasteful spill light above the horizon

Dark sky-compliant luminaires are beneficial to the environment and automatically elevate the overall quality of outdoor products in the market.

Glenn Heinmiller, Senior Associate | Lam Partners
In general, high-quality outdoor lighting is also low-polluting outdoor lighting, so the impact of design practices on some lighting designers is minimal. With that said, I think it has made most designers more thoughtful about the potential negative consequences of their actions. ('Do we really need 400W floodlights on that façade?') All lighting designers have a responsibility to minimize the negative impact of our designs on environmental quality. For manufacturers, I think there is a great opportunity to develop and market new products, but I am suspicious of the proliferation of 'dark sky friendly' labels popping up in advertising. I sense that some manufacturers just see dark sky as a burden to hype their way out of, rather than a great opportunity to develop innovative products. (The equivalent in the automotive world would be: 'Instead of complaining about gas mileage standards and trying to convince us you are doing something, develop a hybrid car!')

Scott Davis, COO | International Dark-Sky Association
Today there are fewer consumers, designers, engineers, and electrical contractors who just 'stick up' any old light. Increasingly, more conscientious lighting design considers and incorporates sustainability in its criteria. Local governments are beginning to recognize the need for good holistic design, and more focus is being placed on lighting that enhances the urban night environment.

Individually, people are becoming more aware that the dark skies of their youth are disappearing for their children. As concern grows, so does the understanding of what prevents a clear view of night skies-glare, light trespass, and sky glow-and why. Citizens are requesting that their local and state governments develop dark sky legislation, which encourages good lighting practice. As a result, manufacturers are designing a wider range of fully shielded fixtures, while designers are responding to codes and lowering wattage requirements, lighting only when and where necessary. Our years of interaction with the public has indicated that even in areas lacking dark sky legislation, a growing number of consumers are demanding fixtures that will effectively and efficiently light their property while remaining ecologically responsible and cost effective.

The International Dark-Sky Association's mission of preserving and protecting the nighttime environment is emerging as a valued priority in all aspects of our society-from the homeowner to the business owner to the manufacturer to the government official. And when we share common goals, there is hope for substantive change.
