Lowering ceiling like Martin Timell. How does he do it here?

[Dagwood]

Planning to lower the ceiling and install spotlights and found a good episode of "Äntligen Hemma" with Martin Timell where he does just that. I was thinking of doing this in the bathroom as well as in the hallway. The bathroom is also going to be renovated and tiled up to the ceiling. My logic tells me to lower the ceiling first, then tile. How should I address the issue of moisture between the wall and ceiling? Plasterboard and filler and painting (possibly a silicone strip between wall/ceiling), is that enough water protection?

Regarding the title, I have these pictures of 3 moments that I don't quite understand.
1. Is this a screw that is simply drilled into metal to metal and stays there?

2. Does he attach this in the same way? That is, he doesn't need a nut or anything on the other side?

3. Same thing here. Is it always the same type of screw?

Grateful for answers

On 1 & 2, yes, a regular drywall screw works, but preferably one with a flat head.
On 3, he uses a drywall screw for metal studs.

You can also install a vertical frame around the walls if you have a smaller distance. Then you don't need to attach it to the ceiling at all. See distance tables at: http://www.norgips.se/getres/index1,530.htm/5f40bc310f2d4c79e802623d545434c4e351fd22.pdf

Best regards,

Oh, a thousand thanks! That was quick you might say
The ceiling in the hall looks like this.

The distances aren't huge so maybe I can avoid fastening to the ceiling.

Thanks

This is part two of the video.
It looks like there is FK pulled in the ceiling or RHH (which would be okay if so).
Also a bit funny because at one point (04:00) where the wires hang, i.e., the placement for a spotlight. Timell places a rule there. Couldn't he have made the board a bit shorter so he could place the rule a bit before the spotlight?

FK? RHH?

Thanks!

Ha ha what a lovely video with a young Timell from the time when people put spotlights in the ceiling

 

[Dagwood]

What, do you mean people don't use spittoons anymore?

Sure, I just mean that in 2004 spotlights were all the rage and people wanted them everywhere. I lowered the ceiling in the hallway myself and installed spotlights because of the prevailing hype. It was the first and last room in my house to get spotlights. You'd be hard-pressed to find worse general lighting, a spotlight lights up just a spot and not much else...

*Clears throat* Poor lighting planning. *Clears throat*

Hmm... I know we have spotlights in the kitchen at my parents' place. Never thought they would provide worse lighting than a "regular" lamp instead.

FK? RHH?

Thanks!

FK are the wires that run in conduits and RHH is a similar cable but heat-resistant. Heat-resistant cables are needed for halogen spotlights.

Spotlights are still in style. However, we have moved from large 50W models to LEDs and smaller spotlights that are used to illuminate things, walls, window recesses, etc.

I don't do many kitchen and bathroom renovations that don't include spotlights. If I don't, it's mainly because the ceiling is not being modified.

shit, better not open doors and windows to create a draft, did you hear a few minutes into the second part that Patrik linked to?

Can a draft really make the roof sag? Can that really be true?

*Cough* Poor lighting planning. *Cough*

Oh well, I set them according to all the rules and sure they light up, but I can never get used to having 9 shadows everywhere I turn. Probably some hidden phobia or something...
