Structured glass shade in cage: pendant lamp Zac The pendant lamp Zac combines round and angular shapes as well as glass and metal as materials. The inner shade of the lamp consists of a glass cylinder, which is finely structured and thus only allows a shadowy view of the illuminant. The glass shade is then framed by a cuboid black steel frame that hints at the modern cage look. The Zac pendant lamp can be hung individually or in multiples, for example in a row above a counter or an elongated dining table.
