Hey #Australia, naive household question - how do I replace this bit of a light, just the translucent bowl that screws in around the actual light bulb? Are there standard sizes, if I take this to a lighting place are they likely to have the same one on the shelf? Or am I going to need to get someone to install whole new fixtures? Our place was missing a few of these when we bought it several years ago and it's finally bothering me enough to do something about it.
