The final chapter in the Halogen to LED replacement project.
It's always the last one, isn't it?
A single halogen downlighter in the downstairs shower cubicle.
Simply replace the lamp: really bad flickering.
No problem: just replace the PSU. The old one will be on flying leads, and I can just pull it down through the ceiling hole, right?
Wrong.
The transformer unit has been screwed to the top of a joist some 6 inches away, and the wiring is in a junction box screwed to the joist beside it.
This was fine when there was access to the top of the joists.
But the loft space has since been converted to living space, so access from above would involve cutting into expensive flooring!
So I need to cut an access hatch in the ceiling from below. Fine.
Turns out the ceiling above the shower has undergone several revisions over the years, each layered over the previous.
Working my way up, like the Very Hungry Caterpillar, I had to cut through:
2 layers of plasterboard;
1 thickness of ceramic tiles ( avocado coloured );
The tile cement, and then a cement or very hard plaster layer;
A steel mesh;
More cement;
2 further layers of plasterboard.
The total thickness was over 3 inches, and it's taken me several hours to cut the access hatch.
This is the only time I've ever has to use an SDS drill to gain access to a ceiling void!
