The lamp has a nice, futuritisches design is, however, built a little too big for my taste. For the size it should shine much brighter in any case. The lamp can be controlled very cool with your phone. There are many millions of colors and many brightness levels possible. There are already numerous apps and you can z. B. with Android smartphones even create the Start Screen Widgets, set with one touch preset settings. Unfortunately, the lamp can not be without smartphone up / turn off that I find very ill-conceived. Would be convenient if at a touch the last selected setting is turned on and in a further touch the lamp goes out. The install would probably not have been so difficult to incorporate.
