ᐅ Number of recessed ceiling lights in the upper floor hallway

Yeah, that’s more of a nightlight than actual lighting.
In the bathroom, at least 3x3 rows, possibly 3x4.
Use light sources with 450 lumens or more, you want plenty of light in the bathroom.
For the hallway, I would also distribute around 8 spots; they can be a bit dimmer, but having plenty of light doesn’t hurt there either.

They look quite randomly placed in the hallway to me.
I would create an isosceles L-shape with 5 spotlights arranged in a straight line. Perhaps the last spotlight in the hallway could then extend into the bathroom?!

Yvonne, yes, the asymmetry was a suggestion from the electrician. There is a metal profile running exactly/about in the middle of the hallway for the drywall. This means one spotlight would be positioned slightly to the left and the other slightly to the right of the profile, rather than both being aligned but not centered.

Are you referring to the spotlight at the height of the bathroom door? So that the row of spotlights continues in a straight line into the bathroom...

I’m now considering having four spotlights in a row, with two on each side of the metal profile.

I will be at the construction site anyway and will try to capture this visually.

I was just about to be really clever when I noticed the retractable attic ladder. I would skip the spotlights. If they can’t even be installed centered and evenly in a hallway like this, it ends up looking poor.

Here is the situation on site:

1. View from the bathroom direction
2. Opposite view of image 1
3. Looking upward; in the lower left of the image, in front of the bathroom and where the other two loops are located, you can see the staggered ones

We have four lights with 800 lumens each in the bathroom, plus an additional lamp at the mirror.
