The Endless linear system transforms its fluid lines into defined rectangular forms with warm, rounded corners, creating the ENDLESS QUAD. This design adds a comforting structural element to functional spaces, offering a simple yet precise geometric definition to ceiling areas that can be used to frame special zones. While elevating the visual design, it also addresses acoustic comfort with newly introduced panel styles that help reduce noise.
Constructed from extruded and die-cast aluminum, the fixture features a durable powder-coated finish for lasting quality and aesthetic appeal. The luminaires are suspended by steel cables complemented by silver braided power cables, combining strength with elegance. The system incorporates a remote emergency option that provides a 1.5-hour (3 hours for EU) lighting facility. This emergency setup includes an inverter module, NiCad batteries, and a remote wall or ceiling-mounted LED charge indicator and test switch. The maximum distance between the wall or ceiling plate and the luminaire is 15 feet (4.5 meters), and the test switch fits a single gang box (not supplied).
ENDLESS QUAD is compatible with a variety of advanced sensor and control systems including Avi-On, Casambi, Enlighted, Lutron Vive, nLight, NX Lighting Controls, Osram, Philips, among others, ensuring flexible integration into smart building environments. Its HPF electronic drivers operate on 120-277V and 347V (EU-240V), with the driver integrated directly into the fixture housing for streamlined installation and maintenance.
The acoustic panels have a Noise Reduction Coefficient (NRC) rating of 0.80 and meet ASTM E84-2018 Class A fire safety standards. Made from 100% recycled polyester fiber (PET), these panels are 12mm (0.5 inches) thick and contribute both to sound absorption and environmental responsibility. The luminaires are designed to mount directly over junction boxes (supplied by others), with an opal polycarbonate diffuser ensuring soft, uniform illumination.
Performance-wise, ENDLESS QUAD delivers lumens based on 4000K light temperature with a Color Rendering Index (CRI) of 90+, and a reported L70 lifespan of 60,000 hours at 25°C (77°F) with an output of 1600 lumens per foot (5200 lumens per meter). The fixture is damp rated for indoor environments with higher humidity, expanding its range of suitable applications.
Designed by Serge Cornelissen, ENDLESS QUAD carries a US Design Patent Pending status. Additionally, seismic bracing kits are available to meet regional compliance requirements, with details available upon consultation with the factory.
