At the Marriott Hotel in Berlin, light and copper have created quite a chilled atmosphere. The entrance area of this hotel in the Beisheim Center is illuminated by a 10-metre wide and 30-metre high light installation made of copper and yellow/gold light. Light shimmers over the level surface in gentle wave movements. Expanded metal panels with LED side trims have been fitted in 72 subdivisions in total while DMX-control devices and LED dimmers ensure simple programming. This enables various lightflows using gentle, infinitely dimmable sequences.
