Vibia Link XXL Ceiling Lamp Ramón Esteve

Link XXL lamps are a Ramón Esteve design.
The Link XXL collection includes four elements
of different size and heights allowing users to create
bespoke silhouettes and volumes on the ceiling as required.
Each potential composition of the Link XXL ceiling light collection
simply requires a single electrical point which makes it a highly
versatile fitting appropriate for all kinds of environments based
on the interconnectivity of the modules. The LED light source can
also be dimmed.
Vibia manufactures the Link XXL lamp in matt lacquered
white and matt lacquered graphite.
