IDA  is an authoritative voice on light pollution around the world.
Our IDA Vic Chapter was formed in February 2015.
IDA Vic  educates lighting designers, manufacturers, technical committees and the public about controlling light pollution mainly in Victoria and where appropriate at a Commonwealth level eg AS/NZ Standards.
We recognize that the best way to accomplish our goal of protecting and restoring our natural night environment is through the promotion of quality outdoor lighting. We provide objective, third-party information and resources for lighting that minimizes glare, reduces light trespass and doesn’t pollute the night sky and support lighting with a correlated color temperature configuration of 3000K and lower. Full cut-off lamps should be implemented as best practice.
France has legislated to turn all unnecessary lighting off 1 hour after close of business and after 12:00 midnight.
This is critical for the protection of wildlife and in particular the Pygmy Possum.
Insect populations world wide have declined and responsible lighting installers and planners need to proactively address this issue and educate their clients for the best outcomes environmentally as well as economically.
IDA and IES have partnered to produce five principles for Responsible Outdoor Lighting.


The Parent Body of IDA Vic is began in America.  IDA have a Dark Sky Approved list of Dark Sky Friendly Lighting including Australian Lighting.

The knowledge surrounding Light Pollution is changing rapidly and how the Community responds at all levels is also changing.

LFA Guidelines Address Colour Temperature

With the advent of the LED, IDAVic is concerned about the potential negative effects of blue-rich white light, even from fixtures with proper shielding. You can find articles concerning the potential hazards of blue-rich white light sources on our Resources page. The scientific evidence has solidified around its conclusions.

The case against blue light is well founded with regard to discomfort glare, circadian rhythm disruption, light scattering, skyglow and biological system disruption in wildlife.

Outdoor lighting with high blue light content is more likely to contribute to light pollution because it has a significantly larger geographic reach than lighting with less blue light. In natural settings, blue light at night has been shown to adversely affect wildlife behavior and reproduction. This is true even in cities, which are often stopover points for migratory species. There is now evidence that blue light can damage cells in the human eye leading to macular degeneration over time.
