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....

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.

We had a similar dilemma and ended up going with a lighting track and it’s great. Good lighting and looks way better than we expected.

Its very like a Beacon one... https://www.beaconlighting.com.au/bellay-5-light-pendant-in-antique-black
