Good lighting – pure and simple

Troldtekt® lighting Good lighting – pure and simple Troldtekt lighting is a series with fitting armatures specially designed for instal­ lation in Troldtekt acoustic ceilings. The solution allows for architectural ­simplicity and pure lines – aesthetics and acoustics in perfect harmony. Troldtekt lighting is a complete ceiling system, consisting of special-cut Troldtekt panels, fitting armatures, all necessary installation fittings, glass etc. The Troldtekt panels are delivered with lamp holes, facilitating installation and saving time at the building site. The design is basic and elegant, the possible combinations are many and installation is simple.

Design and models The Wave lighting series is designed by the Danish architectural company CUBO Arkitekter A/S. The series is characterised by its wavy glass that offers exciting design and optimum light distribution without blinding. The lighting is integrated in the ceiling solution, because the fitting armatures are flush with the ceiling, providing an aesthetic ceiling impression without installed armatures.

One of the major construction challenges today is to make good acoustics, architecture and aesthetics come together in synergy. Troldtekt acoustic panels with integrated lighting ensure good acoustics and good lighting with ceiling and lamps appearing as a single entity. In our inspirational section at, you can find a number of exciting case studies and pictures – here are a few examples:

and Christian Cold continues: „This building has no clinical walls or drab plaster ceilings. The oak wood floors and the large cementbonded wood wool faces create a warm, golden frame around the union. The lighting consists of more than 230 transversal armatures which are beautifully inte­ grated in the Troldtekt panels. The architectural firm CUBO designed the solution and the special wavy glass that shields the armatures to provide optimum light distribution without blinding.” Tailor-made house The users of the building are extremely happy about the design. Helge Geest is CFO of LPSF and says: „It was a very positive experience to move into a tailor-made house with room for our administrative functions, meeting activity and large events. The sound quality is second to none, which to a significant degree is due to ceilings and walls of certain rooms being clad with Troldtekt panels.”
