I chose a 4" (4-1/4") hole to replace the standard lights that came with my new home were delivered. None of the stock lights had ANY marks or markings and we replaced three sets in 9 months under warranty at home. We were able to grab them at Prime Days this year at a very attractive price and they fit perfectly. They're significantly brighter than the bulbs they replaced (which still worked, of course), and the hidden mount was very attractive compared to the OEMs. We chose an oiled bronze as it matches the other lights we added for the pot stands and dining table chandelier. Installation was easy as these units have quick connectors for three position cords in addition to the light itself.
