ᐅ Lighting Design for Spotlights on Exposed Beams / Sloped Ceilings

Hello everyone,

We will start building our new single-family home next March.
At the moment, I am working on the lighting design. Here are the conditions and preferences:

- Recessed spotlights/downlights should be used throughout for general lighting
- In the dining/living/kitchen area, we will have a white-washed exposed beam/board ceiling (the purlin runs along the length of the room)
- In the rest of the house, there is also a sloped ceiling up to the roof. It will not be suspended.

I have already prepared a rough first lighting plan. Due to the limited installation depth, my current favorite are the new Paulmann coins with 110° beam angle and 460lm (white, matte), requiring a 68mm (2.7 inches) cutout.

Question to experienced lighting planners and experts: What do you think about this plan?
The yellow dots indicate the spotlights, the orange ones are additional pendant lights.
Regarding the light output, I aimed for about 300lm in the bathroom and kitchen, and 100-150lm elsewhere.
Since the ceiling is higher and angled at 20°, I expect somewhat less light compared to a standard 2.5m (8 ft) ceiling height. That’s why I chose adjustable beam angles for the fixtures. Is that necessary?

Finally, as a supplement and to illuminate the beam ceiling, I plan to install LED strips of 7m (23 ft) and 5m (16 ft) along the purlin, hidden from view. What do you think about this? Would it be a good addition or part of the general lighting, or rather choose either downlights or the purlin lighting? For example, dimmed to about 25% in the evening while watching TV.

I look forward to your tips and opinions.

Good luck

Konstantin

In the living room, I have now reduced the number of spotlights next to the kitchen to 8–9.

When do you need this lighting in the living room?

I’m not sure, it’s hard to estimate. It just shouldn’t be too dark—that is, for general lighting. So I based it on the guideline of 100 lm/m² (9.3 lm/ft²) for general living room lighting.

Do you still think that’s too much?

I’m asking you, when do you plan to turn on this lighting?

Ah, sorry, I understand now.
For example, at this time of year, in the morning or evening when the children are playing or when setting the dining table.

When watching TV or wanting a cozier atmosphere in the evening, the lighting will be dimmed or turned off. For that, ambient LED light strips will be installed on the purlins to illuminate the beams.

I see what you mean; that makes me think. When and how much lighting do I really need... hmm.

My concern is planning it wrong, because everything has to be installed in the beams or wooden boards!

For the kitchen area, the spotlights should be positioned so that they illuminate the countertop. I would therefore place them slightly more directly above the work surface in your plan. Since you stand in front of it and often lean forward a bit, shadows can be cast easily.

LEDs on the purlin? Well... I am a big fan of floor lamps, table lamps, pendant lights over tables, and so on.

LED strips will be installed along the bottom beam in an angled aluminum profile with a diffuse cover, running along both sides of the room. I have seen this on Pinterest before and want to use it to highlight the exposed beam ceiling and create indirect ambient lighting.

This setup is intended for use, for example, when watching TV or when stepping out onto the terrace and fetching something from the kitchen inside. It provides a nicely highlighted ceiling!

This is roughly how I imagine it.
