The ordered products came from China and was late, but sent within the specified delivery time. The 6x "MR16 60 3528 SMD LED lamp Spot Spot Light Spot Light Warm White 260LM" replace me 20V halogen lamps and even a bit brighter, but still quite pleasant in the light color. With the transformer I had no problems, however, in a lamp with only 2 sockets in a lamp with 6 sockets. There I could only exchange a Stromfesser. When replacing both lamps, the LEDs remain dark.
