Clayton Bay Dark Sky Community Consultation

LED Lighting Installation Update

As the new streetlights in Clayton Bay get switched on by SA Power Networks, we want to take a moment to share some important information with you.

Following community consultation in 2019, Council endorsed the installation of 58 warm- white (3,000 Kelvin) LED lights that meet the International Dark Skies organisation guidelines on 18 July 2022. (Council resolution ACM221597 Item 8.9.1).

We heard and acknowledged the strong desire to protect and celebrate Clayton Bay’s naturally dark skies, and we're pleased to say that this upgrade addresses those concerns.

The upgrade predominantly impacts on land developments where lighting has been designed and built to the lighting standard (AS/NZS 1158) on Alexandrina Drive and north of Alexandrina Drive. Existing lighting on stobie poles has also been upgraded.

The International Dark-Sky Association (IDA) guidelines recommends all outdoor lighting to have a colour temperature of no more than 3,000 Kelvins. That's why Council specifically selected the Sylvania Street-LED Mk3 streetlight in a 3,000 Kelvin warm-white 24 watt configuration. The luminaires are flat-bottomed and point the beam downward to avoid light spill and therefore target and control lighting to where it is needed.

The streetlight upgrade involved removing existing 80 watt mercury vapour street lights in a white 4,000 Kelvin colour temperature, which were responsible for the escape of more blue- light and shorter wavelength light pollution as potential threats to local night-time environment.

This project is a suitable solution to preserving the low-light ambitions of the Clayton Bay community and protecting the natural beauty and dark skies of the area, while meeting the requirements of the Standards Australia (SA) for lighting of roads and public spaces of new developments.

The new lights also increase visibility and safety in the area, making it easier for pedestrians and motorists to navigate the streets at night.

We hope this information has been helpful in understanding Council’s obligations behind the activation of the streetlights.
