First, I have to disagree with where the ceiling installation was described as problematic some reviews.
There is a built-in lamp for Fake ceiling as is more common in offices as in the household. Therefore, you have to improvise something at "normal" suspension directly to the ceiling, of course. The 6-mounted suspensions I checked them for to fix a corresponding suitable depending on the application substructure, especially since you can break away from the lamp, each with a small Phillips screw the angle side.
The lamp itself was very slightly warped here, what is owed to inadequate packaging. While the lamp is packed in total in a profiled foam, but there is no additional stabilizing packaging aids in the form of wooden beams or the like in a box. Another part is due to the transport company that sends the goods. The cardboard came here the way to absolutely intact.
I have the lamp mounted to a subframe at the ceiling, and then the ballast takes place. The 36W LED panel produced a very uniform, diffusely radiating light in a rather cold white tone. However, that was so wanted and is not a criticism. There are alternatively a warm white version. There are no striking differences in brightness of the panel, the entire surface radiates the light absolutely evenly. The processing of the lamp can be described as quite good.
The large surface area, there is less shadow effect than with a single central light source. The light output I feel personally very high, almost garish, which speaks for the lamp. All in all, I would buy the lamp at any time. Possibly I'll buy another one for another room. In terms of durability, I can not say anything, I will add a response in case of problems or failure, of course.
PS: I had problems with the first delivery after a short consultation with the seller, the problem was quickly resolved, however, and my lamp came a few days later on here. Thanks again for the quick response.
