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. From lighting office stairwells, train platforms and station canopies, to parking lots and drive lanes, apartment common areas, school playgrounds, bus shelters, and highway service-area restaurants where stable, comfortable illumination is essential.
Its defining feature is a high-transparency tubular housing combined with the uniform opaline diffusion core, delivering even, glare-controlled illumination with reduced hotspots. The fixture maintains a clean, minimal architectural appearance and stays visually refined both switched on and off.
Engineered for project performance, Steelis Core 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). Standard CCT options include 2700K / 3000K / 4000K / 5000K / 6000K, with tunable white available on request.
Built for demanding environments, the impact-resistant tubular construction achieves IP67 protection against dust and water ingress and IK10 impact resistance. Stainless steel end caps (SS304L / SS316L options) and project-grade sealing support long-term reliability for indoor, semi-outdoor and covered exterior applications.
CORE ADVANTAGES
Uniform illumination with opaline diffusion
A high-transparency tubular housing with uniform diffusion delivers smooth, comfortable light with minimal hotspots—ideal for public and circulation areas.
Single-sided or double-sided emission options
Single-sided output as standard, with double-sided versions available on request for applications requiring balanced light on both sides.
Three diameters: Ø45 mm /Ø70 mm / Ø100 mm
Multiple diameters support different project scales, from compact details to stronger architectural statements.
Custom lengths up to 3000 mm
Configurable from 300 mm to 1500 mm to suit continuous runs, repeated compositions, or standalone features.
Flexible mounting solutions for projects
Wall-mounted, ceiling-mounted, or suspended. Supports single fixtures or continuous lines using dedicated mounting and internal connection solutions for faster, cleaner installation.
Robust construction for public environments
PC tubular housing combined with aluminum louvres and reinforced aluminum end caps.
Designed for durability, impact resistance and long-term use in public or high-traffic spaces.
Stainless steel end caps with project-grade sealing
End caps in SS304L / SS316L with robust sealing design for long-term reliability in demanding environments.
High protection and safety standards
IP67 protection for indoor, semi-outdoor and covered exterior applications.
Impact resistance up to IK10 (PC).
960°C glow-wire tested, compliant with IEC safety requirements.
Advanced control & project-ready options
Compatible with ON/OFF, TRIAC, 0–10V, DALI systems.
Optional sensors and emergency versions available for commercial and safety-critical projects.
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. Its integrated LED system and project-grade mechanical structure are built to deliver stable, repeatable lighting performance over an extended service life.
Built with SS304L / SS316L stainless steel end caps and a durable PC tubular housing, Steelis Core is designed to reduce premature replacement in demanding locations. With IP67 sealing and IK10 impact resistance, it withstands dust, water exposure and everyday site abuse, supporting lower maintenance frequency and reduced downtime across large-scale projects.
The LED light source is energy-efficient and environmentally responsible: mercury-free, with no ultraviolet (UV) and no infrared (IR) radiation—making it suitable for occupant-facing applications and sensitive architectural spaces.
By prioritizing high protection ratings, corrosion-resistant materials and long-term reliability, Steelis Core supports sustainable building strategies by lowering total cost of ownership while keeping lighting quality consistent over time.
