Core drill sizes for 68mm LED spots

We were thinking of about 35 spots. Yes, the core drillings should be done from below and then the electrician would come from above and do the wiring. So it would only be a small hole.

After several consultations with various lighting companies and our construction company, core drilling is questionable. Some could be made, but they would not be allowed to be in a line. In other words, that looks totally stupid. Besides, we really need the large drilling, because these get hot. I’m quite disappointed that unfortunately the spots are no longer possible. We will suspend part of the ceiling, but not too much, since we only have 2.40 m ceiling height. Due to the central ventilation, we have unfortunately lost another 8 cm. I will have to live with it, willy-nilly. Through the partially suspended ceilings, we will still manage to get some indirect lighting. My consolation :-((((

I installed the new Ikea light panels at my buddy's new build over the weekend. They are a cool alternative to the spotlights. They come in 3 sizes: 30x30 60x60 90x30 They provide an awesome flat light. I have almost only installed spotlights myself.
