The U36.41 profiles are available in an integrated version with a C-Shade diffuser frame, BB-Elite modulesand BB-Tube modules.

The BB-Elite modules are based on LFO technology with 30 and 60 degree beam spread angle and with an anti-glare raster.

The BB-Tube module uses LFO optics developed in the Bartenbach lab. Beam spread angle of 30 or 60 degrees. The light source can be adjusted vertically or horizontally by tilting it up to 90 degrees or rotating them up to 355 degrees around their axis.

Researchers at the Bartenbach laboratory in Austria have developed the technology to create a line of modern BB-Elite and BB-Tube luminaires. Its greatest strength lies in what cannot be seen, as light is emitted in a way that is invisible to the eye. Its innovative optics design ensures that light is focused in a as small space as possible and then disperses unobtrusively throughout the room.

Connector designations refer to the shape of the letters of the alphabet or their arrangement against a surface, e.g. ML refers to the letter L. The MH connector refers to the horizontal alignment of two segments joined at 135 degrees.
