After I ordered a trial basis this pears in cold white and this fitted well, I have ordered these here because my cold white version was a little too "cold". These here make beautiful light fit well into the socket. For long-term experience they are far enough in use but for the first few weeks is far everything well.
These bulbs now replace my old high-voltage halogen lamps, which have just a little consumed me with 50W per piece too much.
