interest in LED road lighting luminaires. Many suppliers see it as a business opportunity, but don’t really understand the primary purpose of the luminaire, and how it puts light onto the road – right light, in the right place, at the right time. Luminai res are continually being submitted for consideration. Both AT and CCC have broadly similar approved luminaire lists, ensuring that New Zealand’s roading infrastructure network will utilise the right level of quality and high-performance luminaires equipped with the latest LED technology. Comprehensive review The current NZ Transport Authority (NZTA) road lighting specifications do not reflect the significant technological advances in street lighting. It takes time for Standards (AS/NZS1158) to catch up with advances in technology, and thanks to the introduction of LED technology over the past five years, this change has been particularly rapid. With the long-term whole-of-life benefits achieved by the application of this new technology, demonstrated recently by LED street lighting designs undertaken by the Auckland Motorway Alliance (and subsequently approved by NZTA), there is an extremely strong argument for a comprehensive review of the current NZTA road lighting specifications. NZTA has risen to that challenge. The soon-tobe published NZTA Infrastructure Design Standard 64 SEARCH | SAVE | SHARE AT IDS M30 – Specification and Guidelines for Road Lighting Design combines the respective work commissioned by both Auckland Transport and Christchurch City Council, and encompasses it in one document. The approved list should form the foundation for councils across New Zealand to adopt with a high degree of confidence that they are utilising the best available technology. M30 doesn’t just consider LED technology, it addresses road lighting design in general and provides guidance in support of AS/NZS1158 set of standards. In effect it is an all-encompassing document that is up to speed with the latest technological developments. Summary So, back to the question – is New Zealand backward in terms of LED Road Lighting technology take-up? The answer is an emphatic no. The missing piece of the puzzle is funding. Initial capital cost is the challenge but it is the long-term savings that need to be the focus. Councils across the country are eager to embrace the technology revolution and to push the “Green for Go” button and implement wholesale change to the benefit of communities across New Zealand. save | share Search 44558 at Below left:This image shows a typical New Zealand street with high-pressure sodium lighting. Top right:LED lighting offers substantial environmental benefits and long-term cost savings for councils. But the recent proliferation of businesses looking to supply LED lighting means new standards are required so councils can adopt the best available technology. The NZTA is about to publish the NZTA Infrastructure Design Standard IDS M30 – Specification for Road Lighting. Lower right:Light pollution has become a concern for councils. LED lighting offers dimming solutions, whereby lights can be dimmed at pre-set times without compromising safety and security.
