Hello everyone,
I’m new to this forum and hope you’re all doing well.
My wife and I are currently building a house in Austria; we are constructing a timber frame house with cellulose insulation.
My question:
I plan to install large areas of LED spotlights on both the ground floor and the upper floor (see plan). Attached is a small layout showing my ideas. I intend to use spotlights from the company Ledando (I hope it’s okay to mention the name here), specifically the GX 53 base (due to the limited space in the ceiling) with 5.5 watts, 400 lm, a 120° beam angle, direct connection, and 230 V power supply. In the living room, I want to be able to dim the spotlights.
The points marked in purple are planned as recessed wall spotlights along the staircase.
Can anyone tell me if the number of spotlights I am planning is roughly appropriate, if there are any special points to watch out for, or if there are better alternatives for spotlights?
Many thanks and happy building!

Here are a few additional thoughts on the placement of the spotlights based on what we considered for our own home:
In the kitchen, we moved the spotlights more towards the countertop to prevent your head from casting shadows on the workspace while working. You might want to align the upper spotlights near the wall cabinets with the other lights in the room to maintain symmetry, in case that is ever noticeable.
In the living room, the spotlights are positioned directly above the seating area, so leaning forward towards the coffee table might cause your body to cast shadows.

For recessed downlights (you chose surface-mounted downlights), there are no dimmable options above 5W in warm white.
With a beam angle of 110°, the calculator shows an illumination of 22 lux. On the countertop, you still get around 60 lux.
Of course, there is some overlap with other lights, but with only three additional lights nearby, the total brightness reaches a maximum of about 200 lux.
I would say that sounds unusable.
If I stick to a 36° beam angle, the light will stay where I want it.

Ok, a compromise with the provider you mentioned would be 420 lumens at 60°. This results in about 450 lux on the countertop and 150 lux on the floor in overlapping areas.
At 36°, you would reach 600 lux, which would be too much and too focused.
So at 60°, a correspondingly stronger light source is required. At 36°, less power is sufficient.
At 60°, however, the rest of the room also receives some light.
At 110°–120°, I suspect the spots would need to be more than 7W or installed every half meter (about 20 inches).
