Lighting planning - mixture of spots, strips, and lamps

LED floodlights with 4000 lumens, dimmable, 3000K, that is completely sufficient as lighting

Which ones are those exactly? (a few more characters)

BEG, 30cm diameter, 5cm height,
bought from Obeta 2-3 years ago

We had considered going with 5 spots due to the 36° beam angle and the fairly long corridor to achieve a somewhat more homogeneous illumination.

Your consideration is good but incomplete. If homogeneity is important to you, you cannot just take any fixture, but should look at the light cone that this fixture produces before purchasing. Often the inhomogeneity is already built in. Artifacts, donut holes, strange edges...

LED light gap 25W per/m 2700K warm white, 2000lm/m

2000 lumens per meter is quite a lot. Plan a dimming function. Note on light color: Unfortunately, alone does not provide a reference value for the appearance of the light. 2700K fixtures from different manufacturers can look very different. This is partly because the color rendering usually varies - illuminated materials then look very different despite identical light color. There is a color rendering index (CRI), which is often chosen high (90+x) - but even this does not guarantee identical light. Therefore, visually match the fixtures if homogeneity (see above) is important.

UG:

Garage:
I would reconsider the lighting here.
One LED panel on the left and right side next to the car to illuminate the aisles.
One LED panel horizontally approximately in the middle of the trash bins. This way you have enough light in this area.
I would like the garage to be nicely bright.
At the moment, I have 6 provisional lights with 4000 lumens each on 36 sqm and reach about 400 lux.

Apartment:
Position the light source above the work table. Otherwise, you get shadows.
Possibly additional lighting above the kitchenette.

Technology:
Possibly additional lighting above the laundry room.

Hallway:
Is a mirror planned in the hallway? If yes, then consider additional mirror lighting including a switch.

Our hallway on the ground floor is 1.8 m wide and has a ceiling height of 2.7 m. I have GU10 recessed spotlights with a 60° beam angle, CRI=98, and 480 lm spaced about 1.1 m apart. A 60° beam angle is optimal for our hallway. I can measure how much LUX actually reaches there if you want.
I have also planned with Dialux and measured after installation. Dialux is quite accurate.

As K1300S already mentioned, with interchangeable lamps (at least GU10), 500-600 lm is usually the limit and most have only a 40° beam angle.
The high-quality models naturally have a "nicer, homogeneous light." Unfortunately, they are also very, very expensive.

Stairs: Are these surface-mounted lights?

Ground floor:

Office:
Definitely additionally illuminate the workplace properly.
The light source in the middle of the room is not sufficient.

Living room:
I am a fan of recessed spotlights and think they look nice, but I wouldn’t want them in the living room.
I would tend more towards a floor lamp, dimmable wall or pendant lights.

Pantry: No window? I am glad we planned a window.
If possible, I would not plan windowless rooms.

Upper floor:

Bedroom:
Bedside lamp?

Dressing room:
Mirror with lighting?

Bathroom:
I would additionally consider pleasant lighting.

We have three lighting groups in our bathroom:
1.) Basic lighting with recessed spotlights
2.) Mirror lighting with an extra switch
3.) Cozy lighting with wall and pendant lamps.

Children’s room:
Definitely additional lighting for the workspace.
At the bed a wall, pendant, or floor lamp.
A switch at the bed to turn off the main light.

Otherwise, you have already put a lot of thought into lighting planning. Great!!!
Have seen completely different plans here before.

I currently have 6 provisional lights on 36 sqm with 4000 lumens per light and achieve about 400 lux.

How is that possible? Six lights amount to 24000 lumens, divided by 36 makes 750 lux. Okay, it won't be exactly uniform, but then some areas might be at 400, while others at 1100. That is enough for fine mechanical work. :oops:

How does that work? The six lights provide a total of 24,000 lumens, divided by 36 equals 750 lux. Okay, it won’t be exactly homogeneous, but then some areas might be at 400, while others at 1100. That’s already enough for precision mechanical work. :oops:

Exactly!! That’s 24,000lm. It does sound like a lot, but it is not perceived that way. In my mini workshop, I have about 700 lux. Since I often tinker in the garage, I need decent lighting there. The lights will later be replaced by LED panels and will be at least just as strong.

Since I do photography as a hobby and among other things work with flashes, I own a light meter that can also measure illuminance. Just measured again. On average, I measured 350-400 lux at about 0.9m above finished floor level. What I have to mention is that the walls are still gray and the garage is quite cluttered. Tidy with white walls I should get a higher result.
