From Switzerland.

This lamp from Switzerland is frequently seen at trade fairs, museums and other public buildings all over the world. For this reason, it have rarely been available for private households, although - with its consistent light - it is ideally suited for homes, entrance areas, staircases and offices. The lampholder is pressed aluminium and has a porcelain fitting. The reflector shade is made of triple-layered opaque glass and is held in place by three screws.
