Hello,
we have now been informed by the contractor that they will not be using prefabricated ceiling panels, but will instead cast the ceilings with in-situ concrete.
This makes it relatively easy to install conduits for recessed ceiling lights.
I find it quite difficult, though, to decide on the placement in advance.
Maybe you could share some photos of your lighting setups? I’m especially interested in the living room, dining room, and bathroom ; )
And if you can recommend specific spotlights, I would be grateful for any tips ; )
We also have an internal staircase that doesn’t get much natural light. Perhaps someone has ideas for that too ; )

A quick note on lighting design in the kitchen. Be aware that your kitchen may look quite different in color than it did in the showroom. I recommend testing the cabinet fronts, carcass, and countertop samples under the new lighting conditions, otherwise there is a risk that you might not like the result.
I am currently working on this as well. Meetings with four electrical companies haven’t provided a clear solution, but I have gathered some useful information from each and am trying to base my own planning on that.
One said: You need to specify how many spotlights and where they should go. Another said: I’ll install them for you, but the planning needs to be done by a lighting designer. The next said: No problem, I’ll make a proposal.
On the ground floor, we want to equip the hallway, open kitchen, and living/dining area with LED spotlights. A typical power seems to be around 3.5 watts. The ceiling height is 2.50 m (8.2 ft).
The hallway is 1.88 m (6.2 ft) wide and 6.20 m (20.3 ft) long. I am currently planning a central line of 4 spotlights here. That means 0.94 m (3.1 ft) from each wall to the left and right, then one spotlight every 1.24 m (4.1 ft) (at 1.24 / 2.48 / 3.72 / 4.96 m).
In the kitchen, according to one electrician, the spotlights should be closer together because more light is needed there, and 60 cm (2 ft) away from the wall, right above the countertop edge, so you don’t cast shadows on your work surface. The kitchen has an L-shape, approximately 3 x 3 m (9.8 x 9.8 ft). One spotlight every 60 cm (2 ft), arranged accordingly in an L-shape = 8 spotlights.
The living-dining area is 6.50 m (21.3 ft) wide and 5.00 m (16.4 ft) deep. I was advised to highlight certain zones with lighting, such as the dining table or the stove. However, I prefer a uniform layout regardless of the current furniture plan, as nothing will remain permanently in place. The plan is for 4 rows of 4 spotlights = 16 spotlights for this 32.5 m² (350 sq ft) area.
6.50 m (21.3 ft) : 5 = 1.30 m (4.3 ft) — 5 sections, one spotlight every 1.30 m (4.3 ft) = 4 spotlights
5.00 m (16.4 ft) : 5 = 1.00 m (3.3 ft) — 5 sections, one spotlight every 1.00 m (3.3 ft) = 4 spotlights
This effectively creates a uniform grid over the 6.50 m x 5.00 m (21.3 ft x 16.4 ft) area.
The guideline was that with a ceiling height of 2.50 m (8.2 ft) and a power of 3.5 W per spotlight, the maximum distance between spotlights should be 1.50 m (4.9 ft) to ensure their light cones overlap for even illumination. If it doesn’t look quite right later, it’s still possible to adjust by using bulbs with 4, 5, or 6 W.
That totals 28 spotlights on the ground floor for us. According to my research, this should provide sufficient lighting—neither too little nor unnecessarily excessive. I’m curious to see if it will actually work out that way.
