These perforated ceiling lights made of brass-plated aluminum were manufactured by the German company Hillebrand in the 1950s. They are extremely decorative and cast a beautiful light. There are a few small areas where the brass finish has chipped off, as well as some minor dents; however, these are in no way distracting and do not detract from the beauty of the lights. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution, Up to 250V (Europe/UK Standard).The wiring of this item may be original and might need replacement, if not specified otherwise.
