Ventia's seven-year contract with Dunedin City Council covers lighting design and installation across the city and state highways, operation and infrastructure upgrades including LED replacements, Central Management System (CMS) implementation and renewals.
A key part of this contract is the design and installation of world-class street lighting.
The replacement of 14,000 high-pressure sodium streetlights with a full network of LEDs brings significant benefits to the people of Dunedin, including increased road safety, reduced energy usage and cost, and the ability to tailor lighting levels street-by-street.
The luminaires are all 'night sky rated' which means there is no up spill of lighting, and light fitting design is being adapted to match certain areas - for example, heritage-style fittings around the train station.
Not only are LEDs far more energy efficient than traditional street lighting, but importantly their accurate colour rendering makes it easier to see, which is a major factor in increasing road safety. They also have a much longer, more predictable lifespan than traditional bulbs.
Ventia will replace 14,000 high-pressure sodium streetlights across Dunedin with a full network of LEDs
Twenty base stations have been installed around the Dunedin area that 'telecells' on each individual light communicate with, allowing our team to manage each individual lights.
One of the most innovative parts of the project is the use of adaptive lighting for certain areas such as the sports stadium. This technology means that when an event is on the maintenance team can set the nearby street lights to maximum brightness for public safety, then at a certain time the lights return to their default settings.
