The Tunnel™ suspended continuous luminaire reinvents a classic functional form by incorporating an elegant incurved enhancement that blends refined style with exceptional performance. This design flair not only elevates the fixture’s aesthetic appeal but also exceeds typical levels of output and efficacy, meeting demanding specification requirements. With a wide range of alternatives available for nearly every component, Tunnel enables designers to precisely configure a luminaire tailored to the specific needs of any space. Its luxurious finishes and smooth lines create a sophisticated lighting solution that does not compromise on performance.
Constructed from durable aluminum and finished with a powder coating, the Tunnel fixture ensures both longevity and an attractive appearance. It is suspended using steel cables complemented by a silver braided power cable, providing a clean and polished installation aesthetic. The fixture houses integral high power factor (HPF) electronic drivers compatible with 120-277V and 347V (EU-240V) power supplies, simplifying maintenance and installation.
The diffuser is crafted from opal acrylic, measuring 2.4 inches in width, which delivers soft, uniform illumination ideal for a variety of interior environments. Tunnel can seamlessly integrate into modern data networks through Power over Ethernet (PoE) connectivity, enabling advanced smart lighting control. For applications requiring circadian lighting, the fixture is compatible with BIOS systems; further details are available from the factory. The luminaire also offers tunable white lighting options ranging from 2700K to 6500K to accommodate diverse lighting moods and uses. An RGBW option is additionally available, providing dynamic full-color capabilities upon consultation.
Mechanically, Tunnel luminaires mount directly over a J-box supplied by others, facilitating straightforward installation. Fixture lengths can be customized in 1-inch increments, allowing for precise adaptation to architectural demands; inquiries about specific configurations can be directed to the factory. The fixture demonstrates impressive longevity with a reported L70 lifespan exceeding 60,000 hours at 25°C (77°F) and an estimated L70 extending beyond 165,000 hours at the same temperature, both rated at 2000 lumens per foot (6000 lumens per meter).
An integral emergency lighting option is available, providing 1.5 hours of emergency illumination in North America and 3 hours in Europe. This self-contained system includes an inverter module, NiCad batteries, an LED charge indicator, and a test switch (North America only). Note that the emergency system is not available for fixtures powered by 347V supplies. Tunnel is compatible with a variety of sensors and lighting control platforms, including Avi-On, Casambi, Enlighted, Lutron Vive, nLight, NX Lighting Controls, Osram, and Philips, among others.
Delivered lumens and efficacy are based on LEDs operating at 4000K with a minimum color rendering index (CRI) of 80, ensuring bright, high-quality illumination. Rated for damp locations, Tunnel is suitable for use in environments where moisture may be present. For projects requiring seismic compliance, seismic bracing kits are available; interested parties should consult the factory for further details. This luminaire was designed by Serge Cornelissen, reflecting a commitment to combining aesthetic elegance with high-performance architectural lighting.
