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....

Looking at your lighting plan, it isn't not enough lights, it is where they are positioned. The three lights above island should be spaced directly above island for task lighting. Your plan has them across the kitchen, the same as other three in the middle of the kitchen. If you look at the photos that have been posted with pendant lights, they are all positioned over the island bench, not spread over ceiling. Hope your choice of lighting works well.

Depending on your taste of course, I would introduce some colour - either as tiles or a glass splashback. Personally I think you will need to fill the entire area otherwise there are simply more lines to take in and will create an unwanted feature. We've had a glass splashback painted back and it was super easy to clean. For one kitchen, we've gone for a bright yellow to give it some pop. You can also have photos too but it's not as easy as the file sizes mean that they need to be taken/supplied by a professional photographer. If tiles is your preference, there are many great patterned tiles out now. Good luck!

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.
