Light Track System - Experiences, Recommendations, etc.

Hello,

we are planning track systems for the lights in the living room and kitchen.
Currently, I would prefer a 3-phase 230V system.
Does anyone have experience or purchasing recommendations for the tracks? Or further tips? Or even pictures. :)
Somewhere I had once read the tracks from Eutrack as a recommendation.

Eutrac or Nordic Trac are very solid standards with high variability. Installed 8m of Nordic Trac rail in white and still have 2m left. You can have it if you want. Simple and good.

Thank you for the offer, but we are looking for ones in black ;) Have you already posted pictures of your rails anywhere?

If I have read it correctly, the profile is standardized for the 3-phase rails, so that I can slide lights from different manufacturers into the rails. Right? Does this also apply to (LED) lights that are then in the rail? So preferably not "surface mounted"?

If 2-PH is enough: we have the Molto Luce Volare with Litin AC spots. Very small rail (1.6x1.6 cm) with a central feed that looks just like the rail (no ugly "lump") and the whole thing is also phase dimmable. I just need to cut and mount the cover strips as soon as I am satisfied with the position of the lights.

Do only lights from Molto Luce fit into the track?
