Recessed ceiling spotlight diameter extension

I needed to change some spotlight at home. Couldn't find the exact match so I ordered slighlty smaller (new standard diameter from what I understood). Off course some part of the ceiling were damage under the old spots or event not painted… so… here you have my simple solution. I think pictures are enough to describe the topic.

Had it since more than a year now, no issue at all, no one ever noticed my trick secret !

Hope it helps someone !

Note : I have LED lighting, which is relatively cold compare to old light bulbs. Do not install it if you have hot light source.
