The SIEBE is a recessed downlighter for general lighting applications in an architectural environment. The design of the SIEBE is timeless and pure, it just gives an idea of a hole in the ceiling. The fixture is a well balanced compromise between efficiency and light comfort due to its innovative reflector. The diffussor is recessed in the fixture which gives the SIEBE also good anti-glare properties. The SIEBE is very easy to install in all types of ceilings (plasterboard, concrete, system, rockwool, etc…) without the need of extra accessories. Lamp replacement is also a piece of cake.

The SIEBE is standard available in textured white finish, other colours are also available on demand.
Dimming is possible by simply connecting the dimmable ballasthousing to the fixture.

Materials and finish:

Installation bracket: Galvanized Steel
Housing: Powdercoated Aluminium
Diffussor: Tempered float borosilicate glass
Reflector: Silver/Alumium + Mirror polished

Installation and lamp replacement:

First of all is installing the installation bracket on the ceiling, this can be done without extra tooling for all types of false ceiling systems by simply clamping, for other ceiling systems the bracket can be attached with standard screws or a fixation kit. In this case the ceiling needs to be finished by plaster.
Second thing is connecting the ballasthousing to the lamphousing. This lamphousing can now be fixed on the installation bracket and with the 3 screws you can also adjust the fixture to correct level.
After this you can install the lamps and then you can snap on the diffussor on the housing.
Lamp replacement: Removing the diffussor by pulling , changing lamps, and refitting the diffussor (diffussor fits with snaps)
