Since the layout is L-shaped, the tracks were installed on the ceiling, following the outer perimeter of the layout. I placed an additional track in the middle of the L to accommodate additional spotlights if needed.
The solution adopted allowed me to position the light points as I wished. The spotlights can rotate on both axes. For now, I've used simple E27 LED bulbs.
Important: Please check with the seller to ensure the selected light model isn't about to be discontinued...
... unfortunately, my choice, although functional and in line with my requirements, fell on a series that was discontinued a year after purchase. It's therefore necessary to purchase a few extra spotlights in advance to avoid any surprises later.
