The installation on the ceiling is very very simple. Since the power supply is a separate module and bit larger than the ceiling, this is simply tighten here. The bar has three brackets, which are also easy to assemble. Small disadvantage: the three rod holders have a diameter of about 5mm. Thus, when the hole in the ceiling is higher (almost unavoidable in a concrete ceiling), you can see on the bracket, the hole. I shims mounted here; these look like part of the bulb and cover the holes.
The lamp itself is absolutely recommendable!
