3 not einsetztbar of 3

LEDs are super to power-saving! These LEDs but unfortunately I can not recommend. I have 3 pieces at the seller sebson (also the owner) bought. Unfortunately, all 3 LEDs are not available.

The LEDs cause a very loud and very unpleasant continuous pipes. Approved for use in living rooms can these LEDs not used.

Furthermore, these LEDs cause interference in nearby devices. When turning on / off the LEDs, a master / slave power strip has caused disturbances in the same circuit.

The same errors occurred in all 3 LEDs purchased.

The lamps in which these LEDs should be used, allow only a certain size of the light source. These LEDs were perfect. Too bad that you can not use due to defects.
