To be fair, once I had done some fine adjustment over 3 seasons, mine has been fine for years.
Nightmare for an electrican to install though, as they can’t be around during/after showers to adjust ;)
I have both the first eBay link and fillament ones and can confirm they DO put light out towards the base. And will light a ceiling just like an incandescent. That why they are marked 330 deg
Buy the eBay one then. Cheap and good light output all directions
buy yourself one of these and try it.
I don't think you will be disappointed.

though The ebay deal I posted at the start of this thread is better value
While not filament, these are good for a 60W replacement. 330° light output.
If you want more than one, just ask her how many you require and she will sort it...
yes, filament LED's can come in low output versions, but they don't have to! You can get bright ones too! Their main advantage is when you want light to come out the sides.
If you want light to some out the top, go for the traditional LEDs ones
