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.

Sorry, it is hardly possible to evaluate a mounting location without knowing the fixtures being used. Diameter, luminous flux, luminous intensity, beam angle, color temperature, CRI, control method... Of course, you can use these mounting locations. Whether it will work out or not also depends on other parameters.

In any case, make sure to plan for space on both sides of the countertop in the kitchen.
In the bathroom, I would only use two rows of three lights each. Two rows in the shower area below and one by the toilet. Then place the other row of three centered between the exterior wall and the T-wall.
I don’t quite understand the staircase/hallway drawing. There is a short line marked 0.57 on top and a longer one marked 0.42 below?
I would arrange it roughly like this.

0.42 - O O O
0.42 - O
0.42 - O

or like this

0.42 - O - O

0.42 - O

In the living room, I would consider adding another row. The current layout of the furniture is almost determined by the spotlights. You could also place the sofa freely in the room, but it would still be easy to install two additional spotlights later if the furniture is rearranged. So for now, you might skip that.

As someone mentioned a post before me... there are so many different solutions and approaches when it comes to lighting. It’s really hard to give a simple answer.

I have two other versions here. Do you think one row in the bathtub area would be enough?

Have you already completed the bathroom design with furniture, fixtures, and so on? In the end, we completely changed the bathroom layout and then had a huge problem with the spotlights...

Hampashire has raised some good points. Without the exact data on the spots, ceiling height, and surface reflection behavior, you cannot make a proper plan. I assume that the floor plan and the locations of the furniture are final.
