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....

I would highly recommend redesigning the ceiling fixtures, rather than working around what's already there. It's cluttered and lopsided; and you will probably regret it, or spend much more $ fixing it afterwards. I'm 1/2 way through my kitchen project with a large island hub. To make space for the pendants, I removed two round fluoro's, moved an A/C outlet (and another in the adjacent room with a sky-light), then patched and painted. It's all simple stuff, you just have to design around the ceiling joists, and usually the previous cut-outs are left in the roof (makes it easy to patch). I also installed an electronic sky-light from Bunnings for the in-laws, which is perfect for small roof-space issues. A very small PV panel goes on the north-side of the roof, a slim LED panel goes in the kitchen ceiling, and a long power cable links the two.

They look great in that photo, Northstar! Works beautifully. Will be fine over your bench. Didn't realise how large your p really space will be. Wow! No, if you replace pendants that have staggered drops, the fittings are completely removed and new pendant fittings are installed in their place. The electrician just shortens the drops without cutting them & the extra lenth is hidden away in ceiling.

What is the length of your kitchen island bench? I would suggest it depends on the shape of the pendant lights, but usually they are installed 900-1000mm apart. So in general terms, 2500 bench have two, 3500 bench have three pendants. It seems like you have enough colour going on already. Have you thought about brushed chrome. This would then match your rangehood, fridge and other appliances.
