Ring-shaped LED pendant luminaire Ring of Fire by RZB with cylindrical attached diffuser The silk-matt, mouth-blown opal glass of the diffuser, which grows cylindrically on the outside, is combined with an inner ring of naturally anodised aluminium. This design makes the pendant lamp Ring of Fire look particularly modern and elegant. The light of the integrated LEDs is evenly diffused by the opal glass. The light output can be controlled via external dimmers via DALI if required. Ring of Fire is infinitely height-adjustable from 50 to 120 cm, with power being supplied via the wire pendant. If the pendant length is extended to over 2 m (available on request), power must be supplied via a separate supply cable. The luminaire also allows the integration of TouchDim, brightness and presence sensors.
