Hello, I would love some interior decor lighting advice. We have the attached fittings in our living room - 4 x bulbs hanging from loops of cord with a marble collar around a bare decorative screw-in bulb. They look very bright and glare a lot (particularly as they reflect in the glass wall of the extension). I’d rather not pay an electrician to change the fittings and was wondering if small shades could help…. But I don’t know what shades would work on these fittings (eg work with existing marble collar). Any suggestions very gratefully received! Thank you!
