Style + performance for every space

Designed to balance architectural presence with lighting comfort, this transparent tubular luminaire offers 3 diameters and 5 lengths to match different building standards and design intents.

With UGR < 22, it delivers comfortable, glare-controlled illumination for circulation areas and shared spaces, while the compact form integrates cleanly into tight corners and linear corridors.

Flexible, project-ready installation

Install wall-mounted, ceiling-mounted, or suspended to suit the site layout. It works equally well as a single fixture or in continuous runs, supporting fast deployment across multiple zones.

From standalone accents to long, repeated compositions, the system keeps the installation neat and consistent. Ideal for project execution and ongoing maintenance.

Wall-mounted and suspended installation tubular luminaires installed on a residential building façade, demonstrating clean, project-ready outdoor lighting application
This project features wall-mounted architectural tubular luminaires designed for outdoor residential environments. The solution ensures consistent light output, long-term durability and seamless integration with modern façade systems.

Built to last

Engineered with a fully sealed structure and rated IP67, the luminaire offers reliable protection against dust ingress, water splashes and humid environments. It combines stainless steel end caps (SS304L / SS316L) with an impact-resistant PC diffuser (up to IK10) to ensure long-term mechanical and environmental durability.

Designed to withstand daily wear, UV exposure and accidental impact, this robust construction reduces maintenance requirements and supports a lower total lifecycle cost.
