1 terminal block
Step 1: Cutting the frame
* Cut two arm parts to the preferred length
* On 1 arm part: cut a hole for the plastic end cap, such that is angled 90 degrees to the other plastic end cap (opposed to being on the same side as they are by default).
* On the other part: cut the hole at a 270 degrees angle, such that when both lamps hang down from the arm parts, the wires exit the arms at the same side in the middle.
* Drill a hole in each arm to mount the arm to the ceiling
