The lamp had given at the beginning of an outstanding Einruck. Since I can only agree with all the positive reviews here. The day before yesterday then said goodbye to the lamp. We thought at first that it might be the light source, if necessary, and promptly ordered a new one. Today we went on a real light. Used the replacement bulb teamed up .... nothing. So lamp turned off again, unplug and times closer inspection. When speisung alimentation of the bottom cover then turned the lamp ballast as evildoers. On the side of a hole was burned and melted the plastic. After a simple opening of the ballast finally showed the remains of the defect. A small fire had raged here apparently or were overly "warm" become individual components. Blessing in disguise: it is more nothing happens.
Conclusion: From this company we will not buy more products. I do not know what caused the defect cause, but the trust is gone.
Addendum: We had noticed for some time that the lamp flickered on switched off from time to time slightly. Apparently the whole thing was a slowly emerging process. Caution
