LED compact downlights for external power supply units

Recessed ceiling luminaires with symmetrical light distribution · Trim ring made of stainless steel

LED recessed ceiling downlights for external power supply units, optionally dimmable 1-10 V or DALI controllable. These luminaires are available with different LED outputs, half beam angles and dimensions.

The luminaires and the external power supply units required for your lighting systems can be connected by means of a simple plug connector.

Luminaires suitable for integration in light and building control systems. For integration in an LCN or ZigBee-controlled building management system, we recommend the BEGA Control light control system.


Protection class  IP 65

Cast aluminium, aluminium and stainless steel
Safety glass
Reflector made of pure anodised aluminium
0.5 m connecting cable with plug

An external power supply unit is required to operate these luminaires.
We supply the luminaires 55 821 · 55 822 with an external, non-dimmable power supply unit.

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.


The pleasant illumination invites visitors to enter the building. The forecourt is arranged and structured by LED light building elements. The massive structure, for example a theatre, becomes accessible via a generously dimensional staircase entering the building. Most of the light in this area comes from the ceiling. Efficient LED floodlights guarantee imposing light and give the staircase and...
