This hanging lamp and 2 matching wall lamps were manufactured in the 1960s by the German manufacturer ME Leuchten. The light bulb inside is surrounded by a glass chalice that helps to ensure that the light is nicely distributed by the plastic-enclosed edge. 
The matching wall lamps ensure that the lighting in your room forms a beautiful whole.
 
The lamps are in beautiful condition; both the plastic and the glass are still completely intact. Price is for the whole.
