Hi anybody have experience DIY down sizing the downlight hole by 2 inch? Recently changed the recessed ceiling light to led but size much smaller size.

its easier to buy bigger led. 6inch
its brighter too.

Yes easier if just buy bigger size but in terms of luminescence this size 12w is good enough. Currently with this 12w size already way brighter than before. 😂 so just need to resize the ceiling Hole.

i tried that.. its a big mess. and i absolutely hated fiberglass
end up buy 6" easier.

i am hunting for 6" recessed casing for e27 bulbs. so i dont have to open the plaster ceiling everytime change the lamp.

Resizing need to cut a new piece to fit along w existing hole, then drop in w backing support n mud back the lines

Measure the hole size and cut a portion of plaster ceiling according to the hole size. Then cut the required new lighting hole out of the earlier piece.

Then use plaster ceiling stopping compound to attach the piece to the hole. Prolly can't attach steel support since the difference is small.

I did mine the same way but mine is round shape (changed from 4" to 3" as 3" looks more modern).

I thought of it but 18W is a little too bright considering the number of downlights output i have in the room size.


I thought of buying a sheet of plaster board then cut out a small L piece and join it back to the ceiling. Not sure whether that is how it works though. Does it need steel or something to reinforce?

The L piece is unsupported. Please note gypsum board doesn't "glue" to themselves that well.
I suggest making an "adapter" with border around it as the NEW light spring clips also need a surface to bite onto.

The adapter you are referring to is the wooden sticks that is to be reinforced against the L piece? any suggestion on hold the L piece board against the wooden stick? should i screw it together?

I suggest to cut the whole outline (square to fit existing old hole) and new hole inside it (round or square but for simplicity I draw as green circle - rather than L piece. Because (if u installed these drop in lights) each time u replace them the hole gets looser and more condemned every time u pull out the old light the "outline" of the hole gets damaged by the spring clips.
Whole outline one, can treat as sacrificial outline. Want to revert back to old hole also easy.

You can screw them together (wood sticks to the adapter) by using screws in the gypsum board of the adapter. Plywood adapter also can if u can get the same thickness as existing board. How to attach it to the existing plaster ceiling u can hot glue or just leave it as is.

try do one first.
remember to put on mask and full cover clothing.
later wash the cloth separately.

else itch die you

Could you move the location of the new lights slightly? Cut new holes for them, and completely patch back the old holes. This might be easier to do than making the existing hole smaller with the "L" piece.
