This pendant was made by Ateljé Lyktan in the 1970s. It features a plastic shade with diffuser fitted with two E27 sockets, one can be switched on separately on the lamp. Excellent vintage condition. 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, European Plug (up to 250V).The wiring of this item may be original and might need replacement, if not specified otherwise.
