Commissioning:
By being too large lamp housing (plastic housing) I took some time and some skill, until I was able to place the lamp in the round covers the lampshade. When org. Halogen bulb could put this into the socket and only then unscrew the cap of the lampshade. That, unfortunately, was no longer possible in this size of the new G9 LED and so I had the lamp only then stuck with a lot of tact in the socket.
After commissioning the first time lit only 3 of 5 G9 LEDs.
The reason turned out that G9 versions (at least my) rather side contact in the socket.
Original G9 lamps have at the contacts a small loop bent down which allows the lateral contact in the socket.
With caution, I turned on the LED lamps the two towering straight down contacts slightly to the side so I could also solve this problem.
This problem is likely to be generally applicable to LED G9 base and is not only limited to this model!
Luminous efficiency:
Many a time I've had LED lamps which absolutely did not keep what they promised, but it comes to light output and color I was very pleased with these G9 lamps. Of course, the light color is not quite comes close to the original, but it is acceptable, warm and very close to the original.
The light intensity (brightness) corresponds approximately to the original.
So on the whole, a relatively cheap and good G9 LED lamp
