Those 3 LED halogen replacement bulbs may well be a particularly cheap/poor quality type - likely supplied to the building for free under some government energy saving initiative. At least they're easy enough to replace.
I don't like the ones that are sealed and the whole fixture has to be replaced when it fails (and by a licensed electrician, at least officially).
I've actually repaired a couple that were flickering by resoldering dry joints on the driver board, but to get at the board I had to drill out all the rivets.
