ᐅ Lighting design on the ground floor – Are there any planning guides or resources available?

I would also plan several cables for wall lamps for indirect lighting.

Recessed spotlights remind me of the 1990s, when halogen was new and still up to date.

Furthermore, determine which lights should be dimmable (DALI control often requires 5-core cables).

Also, don’t forget ample power supply for outdoor use (on a separate circuit), as well as separate house number lighting next to the entrance light.

The frustrating thing is that I’m an electrical engineer and covered all of this during my studies… but when do you really apply lighting design in practice?

We will consider the typical ceiling outlets. In everyday life, we usually have indirect lighting on, except when vacuuming or similar tasks.

That means we will use floor lamps as well as wall lamps.

In the attachment, we have marked the points (in red) for the ceiling outlets. Do you have any comments on that?

We also find surface-mounted LED spotlights/downlights quite appealing.

What are your thoughts on this?

Are you serious? That’s far too few—only one vent per room? Five in the bathroom, five in the downstairs hallway, four in the kitchen, and so on.

It depends, since she wants a lot of indirect lighting, which is quite reasonable in my opinion, so it could actually work. In the planning phase, you only see the direct lighting.

We faced the same many questions.
At first, I also calculated using the common online formula, but in the end, contrary to the calculation (60 degrees beam angle), I installed LED spots (230 volts, about 3.5cm (1.4 inches) flat) with a 110-degree beam angle that are dimmable. In my opinion, the difference between 40 degrees and 110 degrees beam angle is quite significant.
I also ordered several spots as samples and chose the best ones. It’s not only the beam angle that matters here but also the color temperature (Kelvin) and personal comfort.
Otherwise, I recommend arranging the spots visually pleasing (symmetrically, with consistent spacing).
Then nothing should go wrong.
Good luck

Thanks for the info, so at least we probably aren’t going wrong with the beam angle.

Do you remember how many lumens you used per square meter per room or how many lumens the spots have? Would 200 lumens / sqm be enough for a hallway, for example, or would that be too “dark”?

Also decide early on which luminaires should be dimmable (DALI control often requires 5-core cables).

Don’t forget plenty of power for outdoor use (separately fused) and a separate house number illumination next to the entrance light.

Tastes vary so much, I find nicely and symmetrically placed spots quite timeless.

Dimmability and outdoor power are good points to consider early on.

The ceiling outlets refer to traditional light fixtures.
If using downlights, obviously more should be installed.

How much did you have to pay per additional ceiling outlet?

60 € plus VAT. 1 switch
95 € plus VAT. 2 switches
