The German manufacturer Nimbus has existed for more than 25 years. Founded in 1988 by the architect and toolmaker Dietrich F. Brennenstuhl, who at that time created his first lamp in a garage in Stuttgart-Botnang, the Nimbus Group now employs about 160 people, and has grown to become one of the leading suppliers of energy-efficient residential lighting, while its sister Rosso, who is dedicated to acoustics, is a distinctive architectural brand for the private, the office and the public sector. Architect and company founder of the Stuttgart-based Nimbus Group Dietrich F. Brennenstuhl describes the philosophy of the company as follows: "We go through our lives with open ears and eyes, looking for opportunities". The combination of high-quality materials, clear, simple forms, and a high degree of technical finesse can be seen in the halogen light Cirrus 0, Brennenstuhl's first light design. Quickly, however, Dietrich Brennenstuhl became unsatisfied by the heat development and light emission of conventional lamps and began to deal intensively with LED technology: the tiny LED lamps offering much more freedom and control as a designers, while at the same time offering the potential to fundamentally change lighting technology, electronics and production processes. After five years of intensive research and development the Nimbus LED was ready for the market in 2005. At the time, one of the pioneers in the area of LED design, Nimbus lighting has been used in more than 10,000 projects around the world.
