The luminaire is suspended by an aluminium rod along a concrete or brick wall. The length of the rod is that of the stand as indicated for a possible stand in the mounting instruction. The luminaire is lifted until the rod is in the horizontal plane and then allowed to fall freely against the wall.

然后(注意蓝字)再将灯具提起,直到铝杆达到水平。如28楼说,可以用手提起灯具一端,铝杆的另一端应是用可以绕轴旋转的方式固定在墙上。然后放手,让灯具与铝杆自由向墙体落下。
