The pins of the outlet-to-lampholder thing look awfully safe!
I just started browsing through de.sci.elektrotechnik
Lots of interesting information! Worst thing seems to be the old german grounding method. They just pull a jumper from the PEN to the ground at each individual Schuko receptacle. This is also the only legal way of replacing an ungrounded receptacle.
One guy complained about the ground of one of his receptacles being live @230V!
30mA RCD protection is required in bathrooms and for outdoor receptacles (maybe kitchens as well, didn't get that sorted out) since 1986, in other areas recommended.
