Adequate room lighting has a positive impact on the comfort of everyday life for household members. A flexible light transmitting tube with a diameter of 350 or 550 mm effectively redirects sunlight to the ceiling diffuser, ensuring even illumination of the interior. Thanks to the option of using the SLO light kit, the light tunnel can also function as a traditional light source after dark.

The light diffuser, installed in the ceiling, gently and evenly distributes natural light without causing glare. Its elegant appearance and modern design perfectly complement both modern bathrooms and more tradditional interiors, such as corridors. The SFZ light tunnel is suitable for roofs with pitches from 15° to 60°. Integrated flashings ensure not only tightness, but also quick and easy installation. Carefully designed installation components guarantee reliability, and the absence of mechanical parts means that the product requires no maintenance or servicing.
Glass
The upper section of the SFZ light tunnel is equipped with 4 mm toughened glass, resistant to changing weather conditions and guaranteeing high tightness. Set in a durable aluminium frame, it effectively protects the interior of the building from rain, wind and dust. The flat form of the structure allows the light tunnel to blend harmoniously with both modern and traditional roof architecture.

Light transmitting tube
The key element of the SFZ light tunnel is a flexible light transmitting tube, whose task is to effectively redirect sunlight from outside to inside the building. Thanks to its multi-layer surface with a high light reflection coefficient, the tube effectively transports daylight to the diffuser installed in the ceiling. Its flexible design allows it to easily bypass structural obstacles, facilitating installation even in hard-to-reach places. This solution provides all-day interior lighting, reducing the need for artificial lighting. The 210 cm long tube can be extended using additional SLM modules – up to a maximum recommended length of 400 cm for a tube with a diameter of 350 mm and up to 600 cm for a diameter of 550 mm.

Diffuser
The lower section of the SFZ light tunnel, visible from inside the room, is finished with an aesthetic ceiling diffuser that evenly distributes natural light throughout the interior. The diffuser with a white, matt cover eliminates harsh reflections and shadows, providing soft, pleasant lighting. The diffuser also has a decorative function, discreetly blending into the interior design. It is also possible to install the SLO light kit, allowing the light tunnel to function as a lamp even after dark.
