As shown in Figure 1, I created three spaces of the same length and width, set up workbenches of different heights, and installed identical lighting on the workbenches

As shown in pictures 2 and 3, the mounting heights of the two lights I placed on top are not positioned on the work surface they belong to, but on the lowest work surface created at the very beginning, and I don't know how to position the lights on the work surface they belong to, and what I need to do about it.
