Position ignition points / LED spots / LED panels

Hello everyone,

we are building a single-family house, currently the ceiling is being done on the upper floor. Now we have to determine the exact position of the light sources or spots or panels as well as the cutouts etc.

Here is the current plan: top left is the bedroom, below are 2 children's rooms, attached is also a picture from the perspective to get a feeling of what the rooms look like. Due to the 6 degree pitch of the roof, the room height is quite large, especially in the bathroom and hallway.

Currently, I have planned many smaller (6cm diameter) spots that can also be tilted/rotated up to 30 degrees. In the bedroom, there is also an additional surface-mounted lamp (yellow circle) (e.g. chandelier etc.)

For the ceiling, a 30mm layering will be done and on top 12mm drywall panels, so that the total depth is only 42mm.

Now we are unsure whether we should go with the many spots or rather use smaller / medium-sized LED panels that look more modern. I have shortlisted the panels from EVN, which are available in sizes 12cm, 17.2cm, 22.5cm, and 28cm in diameter and provide good lighting. Dimmable lights are planned for all rooms; all rooms are wired star-shaped with 5-core cables (from the distributor), so that either DALI or several groups (maximum 3) can be formed, which can be switched separately. The lighting is completely with KNX.

We are interested in ideas and suggestions, somehow we want to completely revise the current plan and go with the panels instead of spots. In the children's room, for example, 2 panels of 22.5cm or 28cm in the upper and lower area, which can be switched/dimmed separately. One panel in the middle would probably be too little to nicely illuminate the room.

Also unsure whether we should really make the cutouts for the panels or just a cable outlet so that we remain flexible later and do not create facts now... how big the panel should be etc. The surface-mounted version can also be considered and the rooms are quite high.

Thanks already!

Regards, Remus

I have had LED panels in the apartment for years and we will also use them again in the new house. We will also use surface-mounted ones because we first want to see if the planning works out. However, we are laying some cable loops in the suspended ceiling on the ground floor and the upper floor so that we can possibly install spots or additional panels later.

Yes, that is a good idea! Unfortunately, with us the ceiling is not suspended but there is only the lathing + drywall:



The electrician said a few cable loops wouldn’t help much here because you would have to put a junction box if you cut the line later and you can no longer fit it in here because the 30mm height is not sufficient (you need about 50mm). Otherwise, you would have to run 2x5-core cables in and out to the lamp, which is hardly possible. But I will ask if there is another solution here. The idea that you can later add any spots or panels is definitely good. Especially because I made everything 5-core, so you could also control the respective light via DALI.

Yes, that is a good idea! Unfortunately, in our case the ceiling is not suspended but there is only the battens + drywall

Hm, ok that is then quite tight. Since you are apparently already quite advanced, I assume that suspending it afterwards is not an option?

Hm, ok that is quite tight then. Since you are apparently already quite far along, retroactive lowering is not an option I assume?

Actually, you could add a second battens (+30mm) and then screw the ceiling on. That would bring you to 60mm, which would be fine. But as it often is when building with GU, they all just want it "quick, quick"... In the bathroom, we will definitely do the double battens, since no panel has been installed there yet. In the other rooms, the ceiling has partially already been installed, so I think they won’t want to take it down anymore.

So, here’s a brief "interim feedback": we also think that we will work with surface-mounted lights. You really don’t want to decide now which size and also whether round or square or something completely different.. Cable outlet is certainly more flexible, you can later "try out" 2-3 lights or vary them. Otherwise, you’ll have to live with the recessed spots/panels forever.

Bathroom might possibly be the exception where you could work with recessed spots/panels, but even there you could basically use surface-mounted lights.

In the bedroom, we are also undecided whether to install a nice chandelier and then bring in light with a ceiling uplighter or something similar. I wired all sockets with 5 conductors, so you can set up two circuits per room, which you can then switch on/off with a light switch. This way, you could also flexibly add more light sources later.

Do you have any idea where the light points could be positioned in the bedroom?
