LED downlights

Symmetrical narrow beam, symmetrical wide beam or asymmetrical light distribution

A new group of very narrow, linear LED recessed ceiling downlights. These luminaires are optionally available with symmetrical narrow beam, symmetrical wide beam or asymmetrical light distribution and in different lengths for your lighting applications. Shallow installation depths, high light output and the high protection class make these luminaires durable and reliable lighting tools for indoors and outdoors.


Protection class IP 65

Cast aluminium, aluminium and stainless steel
Safety glass
Reflector surface made of pure aluminium

DALI controllable

We offer an installation housing for the installation of the luminaires in concrete ceilings and an installation frame for suspended ceilings.

The required installation depths can be found in the instructions for use for these luminaires.

The luminaire luminous flux and the luminaire connected wattage quoted in the table might change as a result of technical progress. On our website you will find data sheets with information on each luminaire concerning not only the current values but also the LED service life and the luminous flux in relation to the respective colour temperature.

Planning examples

On the basis of our empirical values and the suggestions of architects and planners, we have compiled room situations for which lighting design is frequently required. In the following, we shall present possible illumination solutions for these architectural situations. It goes without saying that all technical lighting standards are complied with. In some cases, the degree of illuminance proposed by us may even exceed the standard. For us, the aesthetics of light and a high level of visual comfort are important criteria for such decisions. At the same time, the form and the size of the luminaires must fit into the architectural surroundings. For example, we often recommend larger models if a structure has large dimensions – even if smaller luminaires with lower output would be enough. In such cases, the degree of illuminance can be reduced to a suitable level by means of a light control system.

Staircase with gallery

An open staircase leads into an air space that spans the entire height of the building. The generously dimensioned staircase is illuminated with LED recessed luminaires. Adjustable luminaires are installed in the underside of the stairs, from where they emit their light directly downwards. At the level of the storeys, long, narrow LED recessed ceiling luminaires ensure a pleasant light...

Conference room

The conference room is flooded with daylight through a large window. If required, this window can be darkened. Downlights in the ceiling illuminate the room uniformly and create a pleasant degree of illuminance of 500 lx on the table. On the end wall of the room, there is a presentation screen which is illuminated with surface washers from the ceiling. To be able to work with different media...
