we are currently in the construction phase and are considering how many LED spotlights we need in the living room.
The living room is 40 m² (430 sq ft) and has a terrace window about 5.40 m (18 ft) wide on the south side.
Since I’m not familiar with electricity, volts, and watts, I have a question for the building professionals.
Would someone be willing to take the time to help me plan their placement?
The TV will be mounted on the right wall in the middle.
Thanks in advance.

Hello,
yes, nowadays you really have to study lighting. We first had to think about how much light we actually need. What about halogen bulbs? How do I know how bright they are? It’s a mess. There is only one solution: you have to know the lumen output of the light sources. Nowadays, you can find comparison tables on some websites. A good reference point is that a 100-watt incandescent bulb had about 1500 lumens. Since my eyesight is quite poor, I needed the equivalent of two 100-watt incandescent bulbs to light a room of about 20m² (215 sq ft). That means for 40m² (430 sq ft) I would try to reach at least 6000 lumens. So, 6000 divided by the lumens of the chosen light source gives you the number of fixtures needed (for visually impaired people like me).

Hello
I am also interested in this topic. Our builder has included a fixed number of 30 ceiling spotlights for the ground floor. The builder installs the appropriate halogen profiles in the concrete ceiling. We just need to specify in time where and how many spots we want.
Even after extensive searching, I can’t find any guideline on how much lighting per square meter is recommended for a living space. If I had that information, I could easily calculate how many spotlights I would need, for example, in the living room...
Can anyone help me with this?

What I don’t understand either:
According to Wikipedia, the recommended illuminance for bedrooms, bathrooms, living rooms, and children’s rooms is between 50 and 300 lux.
For a 40m² (430 sq ft) living room, 50 - 300 lux corresponds to a recommended luminous flux of 2,000 - 12,000 lumens.
This means that if I want to use an LED spotlight with 280 lumens, I would need to install 7 to 42 (!!) spots in the living room to achieve the recommended illuminance...
What kind of recommendation is this 50 - 300 range? Why is the range so wide? A recommendation like 50 - 80 or 250 - 300 I could understand, but not such a large range.

Hello aytex, lighting intensity often depends a lot on personal taste when designing a house or apartment. My in-laws sit almost in the dark during dinner, while I prefer it quite bright.
What I did was first decide on one type of LED (for me, 230V 4W GU10 LED spotlights), then I ordered several samples from different manufacturers and tested them at home in the dark. This helped me get a good feel for the required spacing.
The room and furniture layout also plays a role. In my living/dining area (42m² (452 sq ft)) I installed 20 spots arranged in a 1.50 x 1.25 meter (5 x 4 foot) grid, and in the kitchen (14m² (151 sq ft), where I like it a bit brighter) I used 8 spots arranged in a 0.80 x 1.00 meter (2.6 x 3.3 foot) grid.
You can also drive yourself crazy spending hours with lumen specifications and software (Dialux), but honestly, how do most people do it in their apartments? Usually you have a ceiling outlet in the center of the room, buy a lamp from the hardware store, and that's it.
