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

Bathroom: 1 spotlight for the toilet, 1 spotlight for the shower, 1 light in the middle of the bathroom, and otherwise mirror lighting.

Where would you place the spotlight? In the toilet and the shower? I find it uncomfortable directly over the head. We also have a half-height parapet in the shower with a glass wall above it.

I would do it like this. And if the spots are strong enough, leave out the 9er as well. You will probably illuminate the mirror separately anyway.

There is also an illuminated niche installed in the shower. The mirror is also illuminated. Presumably, two spots will be sufficient.

Four dimmable 155mm panel lights fit pretty perfectly for me. My bathroom is designed almost identically. And if you're still looking for a bathtub... take a look at the freestanding laufen pro. They also come relatively slim. It's not the cheapest option, but mineral casting is quite nice.

Light in the house has several functions. already described this at the very beginning. Think about what kind of light you need in which room and at which spot. If you want to vacuum in the late afternoon in winter, when it is already dark, you need different lighting than if you sit in an armchair to read. Your recessed ceiling lights will be able to illuminate the house quite well purely functionally. Expect that you will want additional light sources for non-functional requirements and plan accordingly many light points/outlets. For functional light, a neutral light color and an even beam pattern (flood instead of spot) are useful. In addition, I would definitely pay attention to a PWM-free control (pulse width modulation --> leads to unpleasant flickering, especially when dimming). The recessed ceiling lights are one of many design options for installing lights. If that suits your aesthetic preference: go for it.

Well, I consider my eyes to be good, but I cannot manage to see flickering with PWM in reasonably state-of-the-art equipment.

We have strips and spots here that run with 24V and are dimmed via PWM. They are almost always dimmed on. So far, I have not found anyone who sees any flickering there. These are 1kHz and 1.25kHz dimmers from MDT and Enertex.

At Prediger, you can order a pretty good "Lighting Planning Manual." I believe it was free of charge.
