I was skeptical at first as to whether the price of these lamps is justified - but I am pleasantly surprised. The exchange took place without any problems (the LED lamps are a bit longer than the old halos, but that does not). The Aluummantelung addition still looks great. Only the viewing angle is a bit short, but I accounted for as a learning experience for the next purchase. The light color is still pleasant (more white than yellow).
