ᐅ Planning Recessed Lighting / LED Spotlights

Hello everyone,

I need to finalize the planning for the recessed downlights in our new build this week. Everywhere there will be suspended drywall ceilings. I know you can calculate everything using beam angles and so on, but I don’t have the time for that. Therefore, I followed the rule of thumb of “double the distance between the spots compared to the distance from the wall” and tried to ensure the number of spots provides adequate lighting for the rooms (hallway 100 lumens, living room 200, bathroom 300 L/sqm² (30 lumens/sqft)).

Could you please take a look and let me know if anything stands out, also regarding the dimensions? The attachments are somewhat simple, but I think everything is understandable.

Kitchen:
Spots are positioned directly above the countertop to avoid shadows cast by people. There will probably be 3 pendant lamps over the island. The question here is whether the lighting will be sufficient or if I should install additional spots for the walkway between the kitchen worktop and the island?

Bathroom in a T-layout
The row of spots in the shower and toilet area should be clear. The question is whether just one row of spots near the vanity and bathtub would be enough?

Hallway:
This is a bit tricky since we have the stairway and additionally a recess in the ceiling for the attic stairs. Also, the hallway extends further at the bottom of the plan, but here the sloped roof begins. Is a 1.35m (4.4 ft) distance from the wall too much, and do I need to install more spots in the 47cm (18.5 inches) niche between the wall and the RuckZuck stairs? Is one spot sufficient for the corridor to the left of the stairs?

Living room:
Here I used two colors because the spots should be switchable separately. The outer red ring will mainly provide indirect lighting. All spots will be dimmable. Unfortunately, I can’t provide the horizontal dimensions yet because they depend on the beam spacing.

I appreciate any suggestions, criticism, or feedback.

At the moment, I am leaning towards version 2 from my post #5. If I use ones with a 120° beam angle there, I should be on the safe side, right?

At 120 degrees, with the same thickness and version 2, you will have good lighting.
Possibly also consider an illuminated mirror...

Yes, a backlit mirror will also be installed.

I think I will go with version 2. One last question: 1 or 2 spotlights in the shower?

I would choose option 2 because of the shadow cast.

Small feedback:

In the bathroom, we implemented version 2, but added one more spotlight in the shower area. We used light bulbs with a 60° beam angle and a color temperature of 3000K. The light refracts a bit oddly on the wall, resembling water reflections on pool walls. I might try bulbs with a 120° beam angle here, but overall, we are satisfied with the lighting.
