LED compact downlights

Rotationally symmetrical narrow beam or wide beam light distribution

A series of very efficient downlights which set new standards of compactness and efficiency with their different housing sizes, light distributions and light outputs.

These luminaires are optionally available with narrow beam or wide beam light distribution for your lighting applications.

The high protection class and excellent workmanship make them durable and reliable lighting tools for indoors and out.

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.

Commercial building entrance

The covered area in front of a commercial building is illuminated from a great height with efficient downlights. The focus is placed on the square pillars supporting the roof using very narrow beam in-ground floodlights on the front side. On the sides and at the rear, they benefit from the light of the downlights. A roof panel projecting over the entrance is fitted with recessed ceiling luminaires...
