Installation methods 100,101 and 102 all show the cable laying on the plasterboard.

Hadn't come across that! What a bizarre and unfortunate combination of faults.

Hello - me again!

I'm planning to install 9 low-voltage (12v) fire-resistant LED downlights in our kitchen ceiling and have noted with interest all of the comments so far made to my original posting.

I'm now wondering if there's any good reason why I can't use just one suitably rated 240v - 12v transformer mounted above the old centre-light position, supplying all 9 of the LED downlights using low-voltage cabling.

This low-voltage approach would obviate the possible problems associated with running AC mains cabling through the joists to feed the downlights with 240 v, and the installation of the wiring could then be done much more safely using the 'cut slots in plasterboard, run wiring, and replaster over' technique.

Any thoughts/comments on this alternative approach?

TIA - Dave.

It might be SELV (extra low voltage) but don't overlook the fire risk that still exists.

My honest opinion is - Go for it.

Make sure the transformer is replaceable -ie it fits through a spotlight hole.

Good luck with it.
