I have recently renovated my Brisbane house and being an eco-geek took the opportunity to make my lighting as energy efficient as I could afford and live with. Here is what I found and some tips if you are looking at the same thing.
A graduated scale for efficiency is here but this is heavily effected by cycle period and the fixture. You generally need more downlights than open bulbs. Some colours are more or less efficient. Frosted covers impact brightness.
