I have delighted this lamp on my desk in use and am. The lamp is equipped with a very solid and heavy foot. This gives it a high level of stability. The base of the lamp is equipped with touch panels for operation. The LED array is really very large and the work area lights on my desk outstanding. Thanks to the lamp arm with its joint functions all be needed to adjust positions to take care of each one good illumination of the work surface. The lamp has various setting possibilities with regard to the lighting. You can adjust the brightness individually. In addition, you can change the color temperature and so cold white light (Book icon) to change continuously very pleasant warm light (coffee cup icon). Did they each reached the maximum position, there is a slight vibration alarm. This I find very original. Also you can adjust the lamp a light sleep function. These are a very strong dimmed, slightly shimmering, subtle lighting. Really very pleasant. The energy demand of the lamp is 10 watts. Thus, the lamp is very energy efficient, despite the great luminosity. At the lamp there is a USB socket. It smartphones, tablets can be loaded, etc. This I find very convenient. As a little extra, a cleaning cloth is included. So you can keep the particular lamp base clean and blank. He has a kind of piano lacquer style. I am absolutely convinced of this lamp and forgive 5 Stars.
