Bought two copies in January 2015 One is completely open at the reception. The half sphere transparent stood and left appear the printed circuit supporting the diodes .. (of SMD5630). She has just the soul after 2 months and few. As the upper sphere detaches easily I could check with multicontrolleur with control diode according to two diodes were burnt. We see a very light black dot in the center of the two diodes. One might think that a slight boost is the cause of so many problems (see comments). By trying to push the diodes, their service life is affected. The light is powerful, roughly as a 75 W incandescent and very white, almost bluish making it a little sad but it is a subjective appreciation. In summary, bit expensive but not very solid.
