The power supply of the lamp makes an extremely annoying sound. Depending on is in what stage the lights dimmed, it is louder o. Quieter but still audible even though it is inserted under the desk in the amount of carpet strip and my PC is powered by audible but not loud o. Annoying fans directly on the floor beside the desk , Also in the second model the same problem, so others reported the same thing seems to be set and not an isolated case. The rubber material is a total dust magnet and difficult to clean. Changing the position of the gooseneck is only possible with both hands because the base is too light and otherwise just like kippt.Gut has given me the stepless dimming. The lowest dimming level is unfortunately still a bit too bright, but that is perhaps a matter of taste and does not flow with in my review here. Unfortunately, the lamp smells unpacking extremely Rubber, after two days at the slightly open window it was better.
