We had a Hollywood style Vanity light (i.e. bulbs plugged into a row of bayonet connectors) which over the years was starting to drop bulbs into the vanity basin. Not great.

Replacing with a LED light was a "no brainer".

Only problem with the light was that as it has a low profile back, our electrician had to carve a channel in the brickwork wall to make a connection at the end placed connector from the centrally located wiring.
