Yes, a sizeable estimation could come in handy at some point when dealing with
official bodies when one deals with light pollution.
Iceinspace claims a membership of some 14.000 members I would have thought more like a thousand plus might reside in and around Sydney.
Never mind, this info was just out of interest.
By the way, planning, and testing is under way where app. 45 % of NSW will have its 80 Watt street lights replaced with 18 W LED's with no spill light above the horizontal and with an expected 'option' of a rear shield preventing any light entering private properties should the owner so desire.
