There was a quick delivery. Ordered Sunday and already delivered on Wednesday. The ground (yellow-green cable) is connected to the chassis. The light output is as verprochen very good. I can not say anything because I have the emitters connected only today about the life. Major shortcoming is the too short line. Although I have the junction box mounted next to the lamp, I could not connect the radiator with no extension. The lines in the enclosure are very short, so it is not possible to turn the rear panel to move the Außgang the line from top to bottom.
