Service None

I have 5 pcs. bought these lights for a kitchen lighting. Processing looks at first glance look good, the installation worked well so far good. Only the first LED was already after 4 weeks break. After initial flicker and then significantly reduced power, the lamp no longer went to. Quick to replace the last remaining lamp (I only needed 4 and had one in reserve). After another 2 weeks, then the next LED was kaputt- own fault. When Amazon was not me so helped werden- manufacturer by mail first (no response) and then by letter tried to contact (recipient at the address not known). Conclusion: externally satisfactorily technically a catastrophic failure, service not available. It's really nasty when 2 of 5 LEDs for a short time are broken!
