My flat's main room ceiling lighting is OEM, apart from adding shades and replacing bulbs. It has two dangling lights controlled by a 2-spst switch pair by the door.

The main room of the flat of my next-door neighbour (not the recently aforementioned neighbour) would originally have had the same. It now has a double-dimmer switch pair by the door, a dangling light at one end with a bulb which works, and at the other end a three-bulb ceiling-mounted fitting with no bulbs.

The dimmers would have been installed for/by the previous resident, meaning at least eight years ago, and therefore designed for incandescent filament bulbs.

She wants to have bulbs in the three-bulb fitting.

I remember that nowadays one must be careful about compatibility between bulbs and dimmers.

She is out now, and I have not yet looked at the dangling bulb.

I have not yet found anything up-to-date-looking about this in the Wiki-FAQ..

So, what would it be best to do?

P.S. I'm still catching up on recommendations for Win7 - Win10.
