This lamp had 3 weeks in use. Then began one of the lamps to flicker and a deafening bang the cover glass was thrown across the room and the fuse in the fuse box was thrown out. Incredible stuff. On the (plastic) glass clear burn marks can be seen. Had then the entire shipment sent back, because I did not want to risk that I therefore abfackelt the apartment. On products of such quality I can do without you and I do not want to try because when the next lamp goes off well. Confidence in this manufacturer is far so shaken that I sent back a different type of lamp from this order.
