Perifo直式天花板底座套件（1支燈條）

Installing it was straightforward since the connectors click together solidly, and that 59.1 inch rail gives you a lot of flexibility to span the room. The black finish looks sharp against my white ceiling, and the light bar itself is nice and even with no flicker.

Ended up swapping out my old recessed cans for this and the difference is night and day—the light bar sits flush against the ceiling and the black finish disappears into the room. The PSU at the end of the rail is a bit of an eyesore at first, but once you angle it toward the wall it's barely notice

The two 59.1 inch rails clicked together so cleanly I thought I'd done something wrong, but the straight line looks seamless. Black finish matches my matte hardware perfectly.
