  • Lamp efficacy

    Lamp efficacy

    LED solutions are replacing old and inefficient halogen lamps and standard florescent lamps.

  • Ballast classification

    Ballast classification

    Replacing the existing magnetic control gear with highly efficient electronic LED drivers reduces electrical losses and therefore energy consumption and costs.

  • Luminaire distribution

    Luminaire distribution

    Controlling light emission using optics which bend and shape the light to the correct location.

  • System efficacy

    System efficacy

    Combining optical and thermal control within the luminaire (luminaire lm/W).

  • Presence/absence detection

    Presence/absence detection

    Presence: Lights automatically turn on/off with movement. Absence: Lights automatically turn off and must be manually switched on.

  • Daylight detection

    Daylight detection

    Artificial lighting which responds to the natural light conditions.

  • Constant illuminance

    Constant illuminance

    A function designed to produce correct light levels for the duration of the maintenance period.

  • Task-scene setting

    Task-scene setting

    Allowing the user to set scenes and adapt the lighting to different tasks.

  • Timed off

    Timed off

    Automatic cut-off can be installed to turn all lights off during unoccupied hours.

    Results of actions can be quickly seen as increased or decreased energy use to encourage responsible energy consumption.

Nestled in Sydney's Ku-ring-gai Chase National Park, Australia, Kalkari Discovery Centre is brimming with plants, animals and Aboriginal history to offer a centre for learning through a range of educational activities. A favourite among locals and visitors alike, the centre combines nature and important history with fun games to inform and inspire both adults and children.


The existing lighting at Kalkari Discovery Centre used 50W halogen lamps with magnetic transformer and 36W T8 fluorescent tubes with magnetic ballast. The objectives for the refurbishment were therefore to achieve low energy consumption and reduced maintenance as well as a refreshing new look.

Offering a flexible solution for the centre's displays, D-CO LED is specifically designed as a halogen replacement offering very easy installation. With efficient LEDs and a long 50,000-hour lifetime, D-CO LED ensures the targeted energy savings and low maintenance solution.

For the centre's offices, Polar LED was selected because the troffer offers uniform vertical and horizontal illumination. The light distribution not only provides the correct lighting levels on the desks and task areas but also offers good levels of vertical illuminance, correctly lighting occupants' faces and room walls without the need for additional luminaires.

For a warm, aesthetically pleasing effect, LED lamps are used for general lighting in the main area to highlight displays and add ambience. This LED's large globe was particularly ideal for the existing antique style fitting.

Results and benefits

The new lighting installation has reduced Kalkari Discovery Centre's energy consumption by 74%, which will reduce annual energy costs by $874.76 and create a total carbon emission saving of 0.69kg per annum. Maintenance is also cut from every 3,000-9,000 hours for the halogen and florescent solutions to every 25,000-50,000 hours (8.6-17 years) between the different LED solutions, significantly reducing the associated costs and inconvenience.

Overall, the lighting refurbishment is forecasted to deliver a lifetime net cost saving of $7,489.42 and a payback time of just 3.2 years. There are other areas in the Centre with a lighting refurbishment opportunity too. In terms of lighting controls presence/absence detectors could be installed to further increase energy savings.

Kim Prodanov, NSW Project Lighting Consultant, says: "Ku-ring-gai Chase National Park is really going green, supporting its mission to protect the environment and establish an environmentally friendly reputation. This is just the first stage of the refurbishment project. There are further energy savings to be achieved in the theatre, in all service areas and in the rangers' office. There are many similar facilities across Australia that could soon follow the example of Kalkari Discovery Centre."
