Talking to my sparky yesterday and he said that there were new rules comming out in SA restricting the installation of downlights.
Things like
They cannot be located within 300mm of a flamable material.
Must have complete covers to stop heat escpaing
and a few other things.
At last someone is doing something to stop the risk of these sort of ligths as well as a side effect (maybe intended) it will reduce the power they are capable of using.
