The City of Lights

On 20 February 1962, Perth became known worldwide as the “City of Lights”, as city residents lit their house lights and streetlights to celebrate American astronaut John Glenn on his orbit around the earth on Friendship 7. The city repeated its feat as Glenn passed overhead on the Space Shuttle in 1998.

The City of Perth is undergoing significant change and the city urban designers wanted to know the lighting levels within certain areas of Perth, including Northbridge and the CBD and be able to explain those changes to all its stakeholders.

The project achieved the following:

  • Presenting light results in a simple format for non-technical stakeholders to understand
  • A tool for the city to plan for lighting into the future
  • A tool to understand the lighting footprint of the city

Explaining the Dark Art of Lighting

Lighting is often represented by numerical numbers. Combing customised software, high accuracy illumination meters, GPS and Google Earth®, Citelum have translated this lighting number into a colour and then scaled the average illumination to demonstrate which roads and areas within the city are lit to higher levels of illumination than others.

The audit was conducted using our GPLux® photometric mapping method
