A star deduction is available for the non-uniformity of light color. From 6 LED (1x5er Pack and a single), 2 lights up from the 5-pack in a different, cooler color. They are used together in a lamp shade that looks impossible. Apart from the cooler light is no longer beautiful and reminiscent of the LEDs of the first generation.
Two other star deduction is available for the poor durability. An LED on the 5 pack is instantly explodes at power (no dimmer), while the base is with a bang by braised (clearly visible on my picture). The second LED, which I had bought individually at Amazon is expected after about 15 hours. First she flickered as in a loose contact, then she was completely out. The LED was operated in a completely open lampshade.
I'm going to do my best to spare and sincerely hope that the manufacturers still get the quality problems under control.
