The lamp is dangerous, where the 220V voltage is applied to the palm when screwing in and out of the socket. Here you could get a strong Storm beat easily. Such a thing must not receive a CE mark Good, and should not be sold on Amazon.
A much better experience we got with another LED lamp. The lamp Item no. BK579 of Blypower is miles better combination of luminous efficacy, light color, construction method and security, and also consumes only 15 watts.
A big disadvantage of two lamps, the size of which precipitates much bigger than any normal light bulbs, and thus does not fit in many light sockets.
