I don't find the 150 € particularly expensive.
If I roughly calculate the approximate prices for the concrete box + hole at the filigree ceiling manufacturer + GU 10 spotlight + wiring, depending on which concrete box and spotlight are installed, I easily come to 150 €. An LED panel costs me 75 €.
For consideration in the kitchen, I would also make sure not to cast a shadow on myself while working. So a nice bright work light from slightly in front and a large light source in the middle of the kitchen for the rest of the light.
