The Invia 48V continuous line lighting system redefines architectural lighting by drawing dynamic lines of light that guide spatial perception and enhance the geometry of rooms. Designed for precision and performance, Invia supports room heights of up to 8 meters with a comprehensive range of light distributions. Whether implemented as a recessed, surface-mounted, or pendant solution, Invia delivers seamless, integrated lighting—making it ideal for a wide spectrum of applications, from public buildings and offices to museums and galleries.
The system is engineered for versatility and ease of installation. The core profile contains four conductors: two for the 48V power supply and two for DALI control, allowing seamless digital connectivity and integration. Luminaire inserts snap in tool-free, creating uninterrupted lines of light even through corners and around bends. This modularity enables sophisticated lighting strategies, from general ambient illumination to precise accenting and vertical surface lighting.
Linear wallwashers in the Invia 48V system provide highly efficient vertical illumination with exceptional uniformity. Thanks to advanced optical engineering, even corner transitions are handled smoothly, preserving visual consistency across entire walls. This makes Invia particularly well-suited for museums, galleries, and retail environments where the presentation of vertical surfaces is paramount.
The system also offers compatibility with office-grade lighting requirements. ERCO has developed downlight inserts for Invia that meet strict standards for glare control and visual comfort. Rather than relying on generalized UGR values, these downlights are designed to be arranged in accordance with specific room geometries and work surface layouts, ensuring ergonomic lighting at office workstations.
A defining feature of Invia 48V is the broad array of luminaire modules available for the profile. Downlights for general lighting, uplights for ambient enhancement, and wallwashers for vertical illumination can all be inserted quickly and repositioned as needed. Modules are available with tunable white technology, allowing lighting designers to mimic the natural variation in daylight color temperature throughout the day—a cornerstone of Human Centric Lighting. This adaptability supports circadian-friendly lighting schemes in workplaces, education facilities, and healthcare environments.
In addition to integrated modules, Invia also accommodates ERCO's full range of 48V spotlights via the Minirail insert. This opens the door to highly precise lighting control—from a narrow 5° spot to zoom optics and even framing with tunable white or RGBW capabilities. Such versatility enables lighting designers to create comprehensive, layered lighting schemes with accent, ambient, and vertical illumination all within a single system.
At the heart of Invia’s lighting performance is ERCO's sophisticated lens and reflector system. Downlights use optical polymer lenses to deliver wide flood, extra wide flood, or diffuse distributions, while wallwashers employ highly specular silver-anodized aluminium reflectors for consistent vertical light. Uplights are designed with integrated diffusers and come as compact three-unit modules for efficient ambient illumination. The integrated LED modules feature mid-power LEDs available in warm white (2700K or 3000K), neutral white (3500K or 4000K), or tunable white (2700K to 6000K), ensuring the right light quality for every project scenario.
Each luminaire insert is designed with an anti-glare cover for visual comfort. Downlights are available in white (RAL9016) or black, while wallwashers come in white (RAL9002) or black finishes to match ceiling aesthetics. Housings are constructed from durable aluminium profiles combined with polymer components for lightweight and robust performance.
Control is offered via standard switchable or DALI-dimmable gear, with wireless Casambi Bluetooth control available through a DALI gateway accessory. This allows for highly flexible lighting management, whether via conventional systems or smartphone-based apps.
The profile itself is made from extruded aluminium and can be shortened on-site for tailored installations. Available in linear or corner configurations, it features two copper conductors for power (4.5mm², max 10A) and two additional conductors for DALI control. The underside of the profile accommodates luminaire inserts, while the upper side allows for ceiling attachment or mounting of uplights and connection cables.
Installation options are comprehensive. The surface-mounted and pendant versions are offered in white (RAL9002), black, or silver powder-coated finishes. Covered recessed profiles are designed for flush integration into ceiling panels and are available in black or white, while adjustable flush recessed profiles support ceiling thicknesses from 12.5 to 25mm—ideal for drywall applications.
With its precise optics, advanced control options, and highly modular construction, the Invia 48V lighting system offers a complete architectural lighting solution. It delivers uniformity, visual comfort, flexibility, and seamless integration into ceiling systems, making it a standout choice for any professional lighting design project.
