Coles sells their own-brand bulbs in packs of 2 for $10 (per pack) but the similar Mirabella model is $10 for one.
These are non-dimmable and not smart downlights (cue jokes about being neither dim nor smart).
Apart from any performance difference, is there any safety concern with the Coles brand?
I know there were reports some years ago about similar lights from China and cannot find any assurance through Googling. I would hope Australia and Coles has improved their QA after such reports.
