Not sure about space but it's definitely visible from the top of Mt Wellington and also from a few points across the other side of the River Derwent.
There's a possum that normally walks along the back fence at night - it knocks the occasional light out of place but no issues apart from that. This possum is a brush tail but I've previously had ring tail possums around - for reasons I'm not sure of they seem to be particularly fond of the red globes (but not other colours) and sit next to them when they're on. I assume they like the warmth and are attracted to the red ones for some reason.
Only other issue is those lights in the bedroom window. About 700 bulbs in the window and they do light up the room quite well.
