Unfortunately, the disillusionment followed a few minutes later to hours. From 6 LEDs purchased this variety 2 were broken very quickly (after about 1 hour). Something apparently blown and since then they flicker. More 2 pieces have partial failures of individual LED series. A flickering sporadically and a single (!) Work so far (yet).
Conclusion: A world first that nobody needs. Unspeakable scrap would be the more appropriate description. Please do not buy and save yourself the trouble.
