Hi chittering5 we used the 25.5cm lights. Our island bench is fairly small at approx 1800x900mm. I actually purchased 3 (at much better price than currently listed) but felt it was too many for the space when I mocked up the (widest) diameter of the lights with paper cut-outs. Trying to decide if I can use the 3rd light in the bathroom or something without it looking lonely....

It might be worth while to consider the rest of the space also. Your breakfast bar/kitchen is located quiet closely to your dining table so depending on your kitchen space (apologies, I can't see too much of your kitchen from the photo) you might want to think about the overall style you want to achieve for you entire open plan space, and select pendants that would work for both your kitchen and dining. This is a project I worked on recently that shows how two different types of pendants can work harmoniously in the one space that is most similar to your kitchen and dining set up. Keep us posted on what you decide!

Couple of things to consider..... 1. With any lights above a stainless steel sink, the reflection appears on the ceiling, I don’t like it so I installed a black sink. I added very minimal pendant lights, basically they are spotlights on a stick but they can be dimmed. Also I placed mine off centre. Saying that, spotlights can also be dimmed and sometimes, less is more. 2.Pendants in the bedroom can be quite tricky.. Example...they have to be the perfect height, width and as far as a reading light, they’re not adjustable. They cost more as they need to be installed. If you don’t like them, you need to get an electrician to change them. I originally wanted pendants but opted for lamps, happy I did as my bed couldn’t quite be centred so it would have been a mistake. Good luck, hope this helps.

I like option 1 too, if you are worried about them not being big enough, can you find something like that, but that is bigger than the 16cm? Also, you could go three, I'm posting our former kitchen reno for you, the bench length is 1600 and our pendants were probably around a similar diameter, possibly slighly bigger, and given how heavy ours were in comparison to what you have chosen I definitely think you could get away with three if you liked the look better.
