Hello everyone,

Our single-family house construction will start soon. It has now become clear that the exact positions of the LED downlights need to be specified at short notice, as their housings will be cast directly into the ceiling. Since this is quite costly, I don’t want to install more downlights than necessary. However, having too few would of course be even worse…

On the one hand, I have already read through several forum posts on the topic. On the other hand, I have determined the light cones for downlights with 90° and 120° beam angles and found that these would overlap nicely on the floor.

Nevertheless, I’m still unsure whether my “lighting plan” includes enough LED downlights and whether they are arranged sensibly.

Since many helpful suggestions have already been made in other threads, I would appreciate any good tips you might have for me as well 🙂

Ceiling height: 2.47 m (8 ft 1 in)
Downlights: e.g., the Luxvenum downlights recommended here with 90° and 120° beam angles

Not shown on the attached sketches: under the upper kitchen cabinets, there will be LED lighting for the countertop. In the gallery/void area, one spotlight each will be installed on the left and right sides to illuminate upwards for indirect lighting.

Many thanks and best regards,
Jörg

I won’t comment on the spotlights. For me, they are once again unnecessary to excessive, except for the hallway itself.
But overall, I think the design is quite well done. It is clear and open, with a sensible flow and good zoning. The only issue is the short wall in the hallway, which I find bothersome.

Too many spotlights.

Spotlights extending down the hallway are unnecessary, and the four spotlights in the living area are also unnecessary. Where are the wall lamps?

I’m not a professional, just speaking from my own experience.

Depending on how bright you want it, I think the spacing of the spotlights in the hallway area is almost a bit too wide. The one in the cloakroom will probably not provide enough light. Either go for two or use a ceiling outlet without a spotlight.

For the guest bathroom, the one above the sink may or may not be necessary... I assume a mirror light will be installed there, right?

I wouldn’t extend the hallway, I think. (If you do, you’d probably connect them together, hopefully not otherwise. Also, consider that depending on the setup—KNX, conventional, motion sensors—this has implications. Separate control groups, more switches or push buttons, etc.)

Kitchen, hmm... is it going exactly like that? With the counter? I would distribute the three ceiling outlets more evenly over the counter. It looks a bit cramped as it is. I actually think the kitchen spots are too few. If you want spotlights there, I’d rather go with six. Even if they have a wider beam angle, I imagine that four spots won’t be enough.

I wouldn’t put any spotlights in the living room at all. I’d use wall and floor lamps instead. I find that cozier.

Edit: I just noticed there is a void above the sofa. Is that right? You have to really want that... some might find it uncomfortable. Most voids are usually seen in entrance areas or near the dining table. Also keep in mind that the TV volume will be heard quite directly up there (kids?).
If you keep it that way, you could also consider hanging a cool pendant lamp down from the floor above, like a Hope or something :p

I would agree with almost everything said so far. Overall, there are too many spotlights. In the living area, it’s awful.

Edit2 (today is not my day):

I don’t understand the two ceiling outlets in the bathroom.

Uplights rely on illuminating a wall and reflecting the light back indirectly. I’m having a hard time imagining how this would work here. What does the “gallery” on the floor above look like? If there isn’t a solid parapet or wall, the uplights would only shine onto the ceiling recess. Or am I missing something?
