Qualitatively not well made, light effect is but ok.

After unpacking you have only once a massive stainless steel lamp in her hand. One must then side 2 Allen screws (tool is included) around the lamp to even pull out of the case, which takes you to the electronic zoom. There, the power cables are connected and the wall fittings used (plugs and screws are included). Thereafter, the lamp housing is fitted again.
Striking is the quite poor workmanship of the lamp. For me, some of loosely laid cables were factory already significantly squeezed by the construction of housing and lamp board and the insulating silicone strips for housing seal was pretty full of holes, so could be bad fit. The whole construction between the lamp housing and base plate is downright wrong. Actually, for almost 40, - unacceptable.

The two small SMD LEDs, one for each side, develop a fairly weak light, which really only comes in almost complete darkness, but then very nice advantage. The three different, always two times (for each side) executed screwable filter, thereby producing various effects (a matter of taste). The filter can be combined differently. One can also operate both sides not having a filter or darken one side completely, but this is a shame, because the two LEDs will always light up anyway and a darkened LED then yes nothing 'burns'.

Conclusion .:
Massive partly incorrectly processed the lamp (in my case) is worth the price but not. If you look on the qualitative shortcomings of time, you get very nice lighting effects that would be sufficient as eg TV backlight or as 'signposts' in stairwells or outside areas for me subjectively. Is time a SMD-LED broken, can this not replaced without soldering. Actually, one acquires a disposable lamp here.
