New Downlights Slightly Too Small For Original Holes

I'm trying to replace some old downlights with new GU10 ones. I think I may have measured the holes wrong, so the holes are slightly too big for the new d/lights. The springs on the new ones would probably be ok to hold the new lights in the holes, but the fitting is going up inside the hole.

The instructions say they need 90mm holes, but the holes I have are 100mm. Is there some kind of chrome finisher/ring, etc that will solve the problem? It's only a small difference in size.

These are the lights -

Thanks for any advice.

P.S. The old lights were eyeball type - if this is the right description.

Or some plasterboard and a plasterer.

But seriously, yuou could use these

But then you'd be throwing away/returning the lights you have bought.
Thanks, I was worried someone would say that. So there's no other solution like a conversion ring/bezel available?

If I do have to get bigger lights, where can I get chrome GU10 downlighters similar to the ones in my link, suitable for a 100mm hole? I've only looked in Toolstation and Screwfix, and the ones I have are the biggest they do.
