Perifo 直式天花板底座套件（1支緊湊型燈管）

The two rails and the PSU clicked together effortlessly, and the 39.4 inch plus 19.7 inch combo covers my hallway perfectly. The gradient light is warm at the ends and bright in the middle, which makes the whole ceiling feel deeper than it is.

The gradient tube gives off a really even light, and the black finish looks sharp against my white ceiling. The two rails plus the PSU in the middle made it simple to get a clean 59-inch straight line.

Installed it in about twenty minutes and the gradient light tube looks far more expensive than it is. The 39.4 inch rail plus the shorter one gave me exactly the straight-line look I wanted in the hallway.
