ᐅ Recessed Ceiling Spotlights in Thin Concrete Slab – Drilling?

ScratchiHello!
We have just started the groundworks, and I am currently in the middle of planning our ceiling spotlights. These should fully illuminate the living, dining, and kitchen area. We plan to attach KG caps to the precast concrete ceiling and lay the cables directly through conduits before having the concrete poured. We will handle drilling through the precast ceiling ourselves later on.
Now the question is how to arrange the spotlights. We are a bit uncertain about this. Our current idea is shown in the drawing! Is this sufficient? Which type of spotlights would be best to achieve an even, full illumination?

Hi,
I am interested in the construction using the KG lids.
Which lids, how deep and with what diameter?
Drilling from below according to the marked measurements?
Thanks
AlexejThey will probably be 100mm (4 inches) lids with a height of 5cm (2 inches).
Apply reinforcement from below and then drill through. Place the lids in those spots and later perform the core drilling from below.
Hello,
here are three tips from me:
1.) Sketch the planned furniture layout on your floor plan. A lot depends on that.
2.) Have proper electrical boxes installed by the ceiling installer. The extra cost of about 30 euros per box is definitely worth it to me. Additionally, the components will then be installed precisely according to the manufacturer’s specifications. My recessed lights required an opening diameter of 86mm (3.4 inches). With ceiling cutouts of 100mm (4 inches) and a depth of 5cm (2 inches), there isn’t much room for adjustment. I would also consider the height concerning heat development.
3.) Install a pendant light above the dining table. I was also against it at first, but it looks much better that way.

Hello,
here are three tips from me:
1.) Try drawing the planned furniture layout into your floor plan. It actually makes a big difference.
2.) Have proper electrical boxes installed by the ceiling contractor. The additional cost of about 30 euros per box is definitely worth it to me. Also, these components will be installed precisely according to the manufacturer’s specifications. My recessed lights required a cutout diameter of 86mm (3.4 inches). With 100mm (4 inches) covers and a 5cm (2 inches) height, there isn’t much allowance. I would also reconsider the height regarding heat dissipation.
3.) Install a pendant light above the dining table. I was initially against it too, but it really looks much better.The pendant light is already included in the plan. The boxes cost about 1 euro each, and I can install them after the ceiling panels are mounted. I can be sure that they will all line up accurately. The planning is therefore deliberate and proven.
Ok, good luck with that.
Are you drilling the positions from above with a small hole? Are 5cm (2 inches) in height enough for your lights?
By the way, in my case, the positions matched the concrete factory’s measurements down to the millimeter.
But here’s a tip again: draw your furniture into the plan. And consider when you would like to have which lighting (ambient).
