I'm sorry; but I'm still skeptical. That study was for 9000 homes in
Sidney Australia. They're just measuring the total power used in the
home; lighting is not separated. The report even says that gathering
decent data is very difficult and error-prone.
So it says *nothing* about how many light are on in buildings.
