The Vistosi Bot PL 35 ceiling lamp has a lamp shade made of white, mouth-blown crystal glass. The shade is 34 cm high and has a diameter of 35 cm. The lamp radiates its light directly downwards and into the room. The light is reflected from the ceiling, creating a halo effect around the lamp. The Bot PL 35 is available in three versions: a halogen E27 version and two LED versions. The halogen E27 version can be operated with halogen lamps or LED retrofits. One LED version is dimmable with a trailing edge phase dimmer, the other is 1-10 volt dimmable.
