So far I am very satisfied. A good LED alternative for G9 40 watt halogen.

My first impression is very good, even if the delivery took very long. Behind the seller seems to be a company from China stuck to.
The Hellingkeit corresponds diekten compared my halogen lamps with 40 watts of Osram. Since no distinction is absolutely recognizable. The light color is at full power also absolutely identical and pleasant, only the dimming down you can see a difference because they are in comparison much white then. The dimming function works fine with me. Sometimes, however, briefly to flicker, but stops after a few seconds. In sum, I am very satisfied so far after a day.

Parallel I tested the LED lights in the bedroom lamp. There they strangely do not fit into the socket ... for whatever reason. I can not tell the difference.
Ultimately, now the question of durability open. But I can say something only after a few months.
