Light is actually good base seem untested industry default

I have five of these LED lamps ordered for my lamp with four G9 sockets, all function properly with G9 halogen.
Result was tested by 3 LEDs: a shine as they should, the second shone when she moved a little !!! -> So as a loose connection, the third
not illuminated.

My experience I summarize as follows: If the LED is bright and pleasant. However, I think the base tests in the development of bulbs for pretty sloppy. When you buy these bulbs should not be surprised if they do not work in their lamp although these G9 base has.

The order is therefore revoked and goes back.
