Perifo 直式天花板底座套件（1支大型燈管）

The gradient on this large tube is the standout—it shifts smoothly from warm to cool light, which makes the whole room feel more dynamic. Setup was straightforward with the two 39.4 inch rails locking together cleanly, and the PSU placement at the end keeps everything looking tidy.

The PSU tucks neatly at the rail's end, so the whole straight line looks clean even though the tube itself is pretty chunky. Wiring the two 39.4 inch rails together took me under ten minutes, and the black finish matches my ceiling perfectly.

The gradient on that single tube is what sold me—it throws a smooth wash of light across the whole living room without any harsh hotspots. Setup was straightforward with the two rails and the PSU tucked neatly at the end, so the whole straight line looks clean against the ceiling.
