Ms Elaine Dennehy:

I wish to respond to a question Senator McGreehan asked about the best sources of lighting. They would be the old incandescent bulbs and for our streets generally it would be the sunbeam street lights we have had for decades. They are considered the most healthy light sources. I will pass over to my colleague, Ms Levin, who will comment further on this as she would have more expertise in that area than I would have.
