Architectural lighting is more than functional illumination; it is a structural element that defines spatial geometry, controls contrast, and reinforces material character. The ARC Collection is an ultra-versatile modular linear lighting system engineered to give architects and lighting designers complete creative freedom without technical compromise.


Available in three distinct profile scales—Arc 30, Arc 60, and Arc 90—the collection provides continuous lines of light tailored precisely to project specifications.

Light Distribution Versatility: Direct, Indirect, or Dual Lighting

Every architectural volume presents unique lighting demands. The Arc Collection offers three distinct light distribution options across its profile family to curate the exact illumination needed:


  • Direct Lighting: Focused, glare-free task illumination directed onto work surfaces, conference tables, and reception areas


  • Indirect Lighting: Soft upward light casting a uniform wash onto the ceiling plane, raising perceived ceiling height and eliminating harsh room contrast.


  • Direct/Indirect Dual Lighting: Independently controllable upward and downward light distribution, combining spatial depth with functional task illumination.

Three Scalable Profiles: Proportion & Visual Impact

Designed to maintain visual hierarchy across varying spatial volumes, the Arc family is scaled into three structural profiles:

Minimalist dining room with a long wooden table, woven chairs, pendant light, bowls, books, and pen in warm beige tones

Arc 30 (Minimal Form)


The slimmest profile (20 mm×30 mm). A discreet architectural line delivering precise light with minimal visual presence—ideal for low ceiling heights, private offices, and minimalist meeting areas.


Modern dining room with wooden table, open book, carafe and glasses, pendant light, and city-view windows; calm, minimalist.

Arc 60 (Balanced Proportion)


The versatile core scale (20 mm×60 mm). A balance of performance and proportion, designed for seamless linear runs across open-plan workspaces and corporate boardrooms.

Arc 90 (Spatial Presence)


The largest profile (40 mm×90 mm). Engineered for powerful, comfortable illumination and bold, continuous lines of light in double-height lobbies, galleries, and expansive public space.

Real wood finishes bring organic warmth to a variety of spaces, allowing the lighting system to become part of the architecture. This palette is complemented by natural, black, and white finishes—or high-quality wood decor surfaces designed for projects with strict commercial fire safety requirements.

Optical Systems: Tailored Beam Control for Linear Light

To fulfill stringent glare control standards (UGR) and precise beam delivery, the Arc Collection integrates three optical options:


  • Microprism (M): Delivers diffused, comfortable light ideal for human-centered office environments.


  • Honeycomb (H): Maximum anti-glare control for high visual comfort (featured in Arc 90).


  • Lens Optics (L): High-efficiency, precise beam distribution for targeted accent and task lighting.

Tailored Scalability for Every Scale of Project

Beyond standard lengths (1144 mm to 2280 mm), dimensions, mounting systems, power boxes, and optical layouts can be customized per project specifications.
