Hi,
There are two companies I know of in Sydney that have successful installations of multi-function LEDs (with in-built rather than separately wired sensors) in residential strata buildings.
enlighten Australia http://www.enlighten.com.au
LED Direct Solutions http://www.leddirectsolutions.com.au
We also have a number of written and video case studies on such lighting and the results that have been achieved at http://www.greenstrata.com.au
Cheers
Chris
