Steelis Core
Transparent Tubular LED Light for Comfortable, Reliable Illumination
Steelis Core is designed for flexible vertical or horizontal installation across architectural and commercial projects, including stairwells, train platforms, parking areas, public spaces, apartment common areas, school playgrounds, bus shelters.
Its defining feature is a high-transparency tubular housing with a uniform opaline diffusion core, delivering even, glare-controlled illumination and a clean architectural appearance.
Engineered for project performance, the luminaire uses an integrated LED system (SMD2835) with CRI ≥80 (CRI 90 optional) and ≤3 SDCM for consistent color quality. Rated lifetime is 50,000 h (L80/B10 @ 25°C) with 2700K / 3000K / 4000K / 5000K / 6000K options.
Built for demanding environments, the fixture provides IP67 protection and IK10 impact resistance, with stainless steel end caps (SS304L / SS316L) for reliable long-term use in indoor and semi-outdoor applications.
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.
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.

ARCHITECTURAL APPLICATIONS
SUSTAINABILITY STATEMENT
Designed with longevity and responsibility in mind.
Steelis Core is engineered as a long-life architectural tubular luminaire for high-use public and commercial environments, delivering stable performance over an extended service life.
Built with stainless steel end caps (SS304L / SS316L) and a durable PC housing, the fixture provides IP67 sealing and IK10 impact resistance, reducing maintenance and downtime in demanding locations.
The integrated LED light source is mercury-free, with no ultraviolet (UV) and no infrared (IR) radiation, making it suitable for occupant-facing and sensitive architectural spaces.
With high protection ratings and corrosion-resistant materials, Steelis Core helps lower total cost of ownership while maintaining consistent lighting quality over time.
