Modern architectural lighting does more than illuminate, it shapes spatial perception, enhances visual comfort, and reinforces interior geometry. The Tunto ARC Series (ARC30, ARC60, and ARC90) achieves this through its aluminum profile combined with advanced optics, delivering a functional direct indirect linear solution engineered specifically for human centered offices and modern educational environments where visual comfort is paramount.
Direct Indirect Linear Lighting: The Power of Dual Lighting
A well designed space requires balanced layers of light. Standard downward fixtures often create a dark ceiling, while the ARC Series solves this with precise dual emission engineering:
The Indirect Component (Upward): Casts a soft, wide beam onto the ceiling to eliminate harsh shadows, reduce contrast glare, and create an illusion of greater spatial height.
The Direct Component (Downward): Delivers focused task lighting to work surfaces, meeting tables, or reception desks for optimal visual acuity.
Technical Precision and Safety Compliance
The ARC Series is engineered to satisfy the most demanding commercial specifications:
Fire Code Compliance: For environments with strict fire safety requirements, ARC profiles are also available in high quality wood decor surfaces. This material versatility allows the luminaires to perfectly echo natural walnut or oak finishes while meeting commercial fireproof specifications.
Advanced Glare Control: Can be configured with microprism, honeycomb, or specialized lenses to guarantee low UGR ratings of <16 and <19.
True-to-Life Color (CRI 93+): High color rendering index LEDs offer exceptionally accurate material expression, preserving the authentic visual warmth, organic textures, and rich color profiles of human centered environments.
Component Longevity: Factory configured to an optimal 500 mA current, our integrated LED modules exceed 50,000 lighting hours for maintenance free reliability.
Smart Ecosystems: Fully compatible with DALI, DALI2, and Casambi networks, allowing for independent control and dimming of the upward and downward light loops.
Tailored Scalability for Every Scale of Project
Made from aluminum, the series is defined by its clean geometric profiles, available in three distinct, scalable variants to suit any space.
Whether specified in classic natural aluminum, black, white, a custom RAL color of choice, real wood veneer, or wood decor surfaces (Fire Code Compliance), the series behaves as a fluid architectural element.
ARC30 (30mm Height)
The most slender, low profile variation. Its compact vertical dimension ensures a light, unobtrusive presence, making
it ideal for standard ceiling heights, meeting rooms, private office desks, and spaces where the lighting must quietly integrate into the interior geometry.
ARC60 (60mm Height)
The versatile core scale of the family. Offering a perfectly balanced vertical profile, it steps up the structural presence to command open plan workspaces, large corporate boardrooms, and medium scale commercial interiors without overwhelming the visual field.
ARC90 (90mm Height)
The most robust, high impact statement scale. Developed specifically to anchor grand, large scale spaces, its substantial vertical profile prevents the fixture from getting lost visually when suspended in expansive public lobbies, double height galleries, and major reception areas.
