The Marset Plaff-on 50 is a wall and ceiling lamp with a diameter of 50 cm. It consists of a lacquered aluminum ring with a mouth blown opal glass diffuser. Most of the light is emitted directly. The aluminum ring around the diffuser also directs the light indirectly, creating a halo on the ceiling or wall. In addition, the ring also directs the light emitted by the diffuser to the side, so that it is emitted directly. From the inside the ring is always white, from the outside it is available in silver grey or black. The Plaff-on 50 is available as a halogen or LED version. The halogen version can be operated with halogen lamps, LED retrofit lamps or compact fluorescent lamps. The LED version has an integrated LED module. Both versions can be dimmed on site. On request, the LED version is also available as a DALI dimmable version.
