Putting new light into a joist

[Gio M]

hi all.
My renovation isn't going according to plan. Everything that can annoy me is annoying me.

Hope someone can help. I have a light fitting for my living room. It's 9.8kg so the instruction make it clear that it needs to be in a joist. If it was lighter I'd maybe use plasterboard anchors but I think at 10kg it's asking for trouble.

As per the image I have a joist running approx 9cm to the left. I could easily attach the light into this however it won't be in line with the downlighters on either side. Is there a safe way to brace onto the joist 9cm away to bring the light fitting in line with the downlights.

The irony is the original light fitting was in line with the joist but the electrician moved it because obviously the downlights could not be fitted in line with it.

Last thing I was to do is tear a larger hole in the ceiling than I need to and have to get the decorator back in to patch up and paint.

lift the floor above and fix a noggin exactly where you want the light to be, fixing it firmly to the joists.
you might find it easier to channel out a cable route in the wood before final fixing, can't tell from they picture

Gio M, good evening.

How about you consider fixing a ceiling "Rose" made of timber?

The rose could span and fix to at least one Joists, the Light could then be suspended from the Rose?

If the rose is of sufficient thickness it will be able to support 10 kg

But all depends on the possibility of introducing a Rose into your ceiling configuration? the Rose could be any shape at all?

An offset [eccentric] load of 10 Kg that is 100.mm away from the fixing of the Rose is just about doable you could also add glue to the interface of the Rose and the Plasterboard?

Just a possible way around your problem??
