We love light and the challenge of creating innovative lighting solutions that set rooms and objects in the perfect light.
Our guiding principle is to provide light for people, planning and designing our lighting solutions accordingly. We use the simple effect of intelligently placed lighting to intensify architecture and the ambience of a room. With our intelligent lighting solutions, we want to positively influence people’s biorhythms, which are influenced by light.

We demand and expect high quality: our internationally experienced, multidisciplinary team works with the latest computer programmes and uses innovative technology. We develop uniquely distinctive, forward-looking lighting solutions at the highest technical level for discerning customers, architects and investors. We exploit the possibilities of the latest lighting technology and combine it with good design. Technically, there are hardly any limits to what we can do. We select optimal products for convincing results, independent of manufacturers.

To protect the environment, we take care to avoid light pollution. We attach great importance to energy-saving lighting management. By choosing optimal equipment, we help to reduce electrical network pollution.




The LIGHT ON team consists of internationally experienced, inter-disciplinarily trained and carefully selected lighting specialists. They demonstrate a high level of competence in lighting technology, creativity and experience. We inspire our numerous clients, some of whom have been with us for many years, with creative and technically sophisticated lighting solutions. With a lasting enjoyment for this exciting work and high expectations of quality in all areas, our LIGHT ON team, together with CEO Felix Kessler, are known for “the art of fine tuning light”.




The history of LIGHT ON is inextricably linked with that of its founder, CEO Felix Kessler: He graduated as a precision mechanic from the Physics Institute at the University of Zurich. During his further training as a lighting designer, which he completed at the same time as his classical ballet training in London, his special talent for light became clear. He sees and feels the subtlest nuances of light, intuitively combining natural light and artificial light into a coherent whole.

Thanks to various sponsors, this special talent led him to the State Opera of Pretoria in South Africa. At the age of 24, he was already responsible for the lighting of his first opera. During his 7.5 years there, he worked his way up to the position of first lighting designer. In his spare time he lit open air concerts and film productions. After returning to Europe, his passion for classical music and perfectly lit productions led him to the Salzburg Festival in Austria. He then studied to become a lighting technician at the Hanseatic Academy in Hamburg.

At a time when few architects and clients were aware of the importance of light for architecture and the ambience of rooms, Felix Kessler founded his company LIGHT ON in 1992 – Switzerland’s first full-service architectural lighting company. His decades of experience, his pioneering spirit when it comes to the use of innovative technologies and his extensive professional network have made Felix Kessler and his LIGHT ON GmbH one of the top Swiss addresses for projects that are demanding in terms of lighting design and lighting technology.

Painting with light and enhancing the special features of a room or architecture is like designing a stage set for me“.

Felix Kessler, CEO LIGHT ON



For 35 years, LIGHT ON has always been at the forefront of technical innovation. As Swiss lighting experts, we share this innovative spirit with LED Linear – one of the innovation leaders in the field of new LED technology. We were already involved in the development of the first ULTIMA prototypes as “early adopters” and therefore know the product with its outstanding properties down to the last detail. At LIGHT ON, we know how this new nanotechnology can be used to perfectly implement customer wishes. Or how architects can successfully integrate this forward-looking lighting technology into their architecture or into special luminaires. Because the minimalist designs open up a completely new world of light. LIGHT ON will be happy to help you discover and get to know this world.
