Good work Julian. In my own local fight against a nearby development i encountered the Australisn Standard for Outdoor Illumination. AS 4282-1997. It is badly out of date (like 20 years ) and does not mention LEDs at all. But it is all there is and it gets cited in every DA where lighting is used. My local government area just fell back on that Standard and showed no interest with more recent findings on LP impacts. I wish you good luck in the fight.
