From the luminosity ago these LEDs are quite with the previously installed 20W halogen bulbs comparable, but the light is not quite as warm as we were used by the halogen lamps. The pins I had to do something so that shorten the lamps completely fit into the socket. To ensure a long service life of the halogen transformer was immediately replaced by a sebson LED driver, this done now unobtrusively his services in combination with the LEDs. All in all, the sebson LEDs better than several competitors that I have already been tested.
