Attention cable suitable with switches and plugs, not for ceilings in Germany

This is not the first puzzle lamp that I purchased. It was striking to me that the plastic this lamp is thinner than that of the bulbs that I bought some time ago times more expensive.
Whether this is an advantage or disadvantage I do not know, the build is easier with thinner plastic. In the old lamp but a part is already torn, whether the then happens faster when thin, could be.

Caution Caution: The cable has a plug and a switch. So no use in Germany as a ceiling lamp, it is necessary to buy a separate version.
Unfortunately, this is not described as accurate, therefore only 3 stars.
(In Italy I've seen on the ceiling connector for lamps, because the would presumably).

Otherwise, the lamp is super visor - free, have no other found where you never daily in the bulb. Therefore, I love these bulbs like this.
Assembly instructions rather poor. In Youtube there are better for people who have difficulties.
