Lighting design for a multi-story apartment with indirect LED lighting

always in the center of the intended space. Centered toilet and centered shower.

Always preferably so that you yourself are not between the spotlight and "where I want light" Then rather one more spotlight in small rooms. Otherwise, your own shadow can be disturbing

The visible is in the area of ~100 Hz, sensitive eyes can manage up to ~400Hz.

100Hz PWM is quite common with poorly dimmed LEDs, often even far below.

Where would you place the spot?

If you look at recessed ceiling lights and light bulbs, you will get a specification for the beam angle. This then determines, together with the ceiling-to-floor distance, the illuminated area on the floor. We have installed lights from Luxvenum and Ansorg in the ceiling at some places. On the latter manufacturer's website, you will find very good technical drawings that help you to estimate beam angle, illumination area, and amount of light at which power. Don’t make the same mistake I made at the beginning and think "more is better, I can just dim". Also remember that there are recessed lights that have a design that allows adjusting the light outside the "plumb line".

So, I have adjusted the planning again. In the sanitary rooms, I went over the mirror lighting and excluded spots for this. In the study, I have planned 3 spots in the center – task lights will then be realized via sockets as desk lamps or similar. In the living room, I am relying on 4 spots in combination with an L-shaped LED aluminum profile. The dining table will then be illuminated by its own light source (possibly a pendant lamp). In the kitchen, I am still unsure about the positioning of the lights. My idea was rather directly above the countertop so that it is well illuminated; however, you often stand directly at the countertop, so there might possibly be shadows on the surface. In the hallway, I have also added a mirror, possibly with lighting.

I'll comment:
Bedroom: You can skip recessed ceiling lights if you hang a good central light for functional lighting. I imagine the positioning of 1 and 2 to be uncomfortable; I would work with "bedside lamps" there. Socket or wall outlet.
Dressing room: Functional lighting counts here. Take several recessed ceiling lights positioned so that they lie between you and a mirror surface. It's good to recognize colors when dressing. Therefore, high-CRI and a neutral light color are especially important here. The positioning of 5 and 6 does not fulfill this.
Bathroom: You can do it like this. I would place 8 and 10 closer together and align them geometrically in the center. Remove 9. If you have a lit mirror, then you can also skip 11.
Study: Thinking of recessed ceiling lights without the furniture usually goes wrong. It will look "random."
Living-dining area: Recessed ceiling lights in the living area wouldn’t be my favorite. You get some flexibility with adjustable models. Two outlets above the dining table seem sensible.
Kitchen: Not easy to assess without seeing the kitchen. In some places, under-cabinet lighting is advantageous, then no ceiling light is needed in addition.
Hallway: Deviations from symmetry need functional or optical integration. Of course, I can’t recognize that.
WC: one central light is enough. Consider a wall solution above the sink.

thanks for participating in my post, I’m very happy about it!
Numbers 1-2 are planned as wall lights - I haven’t picked a model yet. We’ve planned sockets here anyway :)
The ceiling lights were mainly planned in case a wardrobe ends up in front of the bed, as the lady might not manage with the space otherwise.
Dressing room: I will probably place the ceiling surface-mounted lights centrally, since the wardrobe will be flush against the wall towards the bedroom on one side and placed against the outer wall on the other.

The positioning of 5 and 6 does not fulfill that.

5 & 6 are in different rooms - I think 6-7 was meant, but I see the issue.

Bathroom: You can do it like that. I would place 8 and 10 closer together and align them geometrically centered. Remove 9. If you have an illuminated mirror, you can also save yourself 11.

With 11, it’s simply a light source, in this case an illuminated mirror.

Office: Thinking about recessed ceiling lights without the furniture usually goes wrong. It will look "random".

So I’ll try to briefly share my current thoughts. I will place two desks on the wall side towards the living room (No. 165) so that we have a “workspace.” On the other side, there will initially be a wall cabinet for documents, cleaning supplies, etc. How we plan this so that it can later become a children’s room without completely throwing out the lighting concept, I don’t know yet.

Kitchen: Without seeing the kitchen, it’s hard to judge. In some places, under-cabinet lighting is advantageous, then no ceiling light is needed there.

In the ground floor apartment with an island - upstairs only as a U-profile. Front colors can be ignored for now.

Hallway: Deviations from symmetry require a functional or optical integration. Of course, I can’t see that.

So 36 would be an illuminated wall mirror here again. I still have to decide what light sources 14-16 will be, which optically fit best.

In general, we are coming closer! :)
