The International Dark-Sky Association Victoria is an authoritative voice on light pollution in Australia. IDAVic educates lighting designers, manufacturers, technical committees and the public about controlling light pollution. 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. To achieve this, we developed the Light fixture Accreditation program to provide objective, third-party certification for lighting that minimizes glare, reduces light trespass and doesn’t pollute the night sky.

IDAVic does not sell lighting. Our first accreditation for Products available in Australia is for handrails as listed below.
LFA Guidelines Address Color 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. The is now evidence that blue light can damage cells in the human eye leading to macular degeneration over time.
The IDAVic Light Fixture Accreditation program only accept products that offer a listed correlated color temperature configuration of 3000K and lower.
