What ribbon should be matched with the white ceiling light trough

It's best to use that light strip because it's soft, it can change with the shape of the roof you hang, and it's easier to install. Just like the side-lit headlights of the EHLTECH, they also use light strips.

This is called the built-in light trough.

If you want to do it, it is more troublesome - you need to divide the ceiling into two ceilings and two edges. Wiring and installation of built-in lights are required. >>>More

The light trough is calculated by meters, and the secondary top is calculated by square Generally speaking, it can be calculated like that, depending on how you negotiate.

The light-colored ones are better, beautiful and generous.

I think it's better to pair it with a white cotton sofa. If you're not satisfied, look it up online. Thank you.
