Hi guys. I need to install some downlights but don't have enough space in the void above. The lights that were there before had a white spacer slightly larger than the lights that lowered them by about an inch from the ceiling so creating a bit more headroom. Does anyone know what they are called or where i could source them please. going round in circles on google. They are eyeballs so needs a 90mm hole in it. Cheers. Gary
