Spot planning - But how? Problems in some rooms

Voltus has 60° as well

Except Voltus. I am looking for one that can be integrated into Dialux...

So in the KNX forum someone has the 60° in Dialux;)

Maybe take a look at Opple.

Good that a floodlight for Dialux could be found. As an alternative to these recessed ceiling solutions, there are also quite affordable proper flat LED panels. We have oriented ourselves towards functional lighting in the commercial sector and will use Ansorg or Zumtobel. By the way, the vendors' websites are excellently informative; prices are available from the electrician. Also really nice and good is Prediger's house brand, although it gets a bit more expensive there.

Now I have found from Osram what I was looking for, but unfortunately the download file for Dialux is defective and I can't find any other alternative...

I have now also found one with 60 degrees and planned accordingly. The rooms look quite good so far, only the living/dining/kitchen area is extremely difficult to implement because you have to go around 2 corners and everything should still be a bit symmetrical somewhere.

Remember that you need more light in the kitchen to be able to cook comfortably - accordingly, size them stronger or position them closer together. In the kitchen, I recommend a cooler light color than in the other areas.
