I plan to purchase and install LED spotlights myself in my prefabricated house. The lighting outlets will be prepared by the house manufacturer. Can anyone recommend LED spotlights with a good price-performance ratio and possibly a suitable online store? Preferably both dimmable and non-dimmable options. Are there general guidelines on how many LED spotlights should be planned for a certain living area?

And which suitable sockets/frame holders do you have? There seem to be considerable differences in price and quality here as well.

Are GU10 bulbs used – sockets/frame are a completely different matter, although I personally place more importance on the bulb itself.

We ordered our LED lights online. There are many suppliers that offer good quality products for a relatively low price. However, like the previous commenter, I am a fan of Philips.

At what distance have you installed your LED downlights? (I am planning to use GU10 LED spots, each with 5 watts).
What do you think about GX53 recessed lights? Does anyone have experience with them?

The distance depends on the beam angle and the ceiling height.

This can be calculated quite easily using the tangent function.
Tangent alpha = Opposite side / Adjacent side

Opposite side = Radius of the illuminated area on the floor
Adjacent side = Room height
Alpha = Half of the beam angle

Rearranging the formula a bit:
Radius of the illuminated area = Tangent (beam angle / 2) * room height

I then drew a sketch of the room, arranged the ceiling spots "as desired," and used a compass along with the radius calculated above to mark the illuminated areas. If there are any dark spots, the position of the ceiling spots needs to be adjusted or additional spots added.
But be careful: if the spot is supposed to illuminate, for example, the countertop, then the distance from the ceiling to the countertop must be used in the formula instead of the full room height.

Wow, we didn’t do this work ourselves. We spent one day on the shell construction with our electrician, and we were done.
Before that, we had to mentally arrange the furniture.
