I got me 3 pieces of these lamps ordered and after 4 months were all broken! That is why I am very disappointed by the company Lumíra this article. Because I was curious and electronics have learned I opened these lamps and realized that with a capacitor on the Vorschaltplatine had burst, with the other two are on this very Vorschaltwiederstände Board burned !! See attached Kundenbilder !!!!! Something like this circuit must not be and I can not believe that the May carry GS mark. If anything I'll try LED lamps another company. 1 star because it worked well for a few weeks !!
