TUNNEL reimagines the classic functional lighting form with a sophisticated and charming twist, thanks to its gently incurved profile that brings elegance to any interior. This sleek design is not just about style—it’s also about performance. TUNNEL delivers superior output and efficacy, exceeding the expectations typically associated with linear luminaires. It is engineered to offer a wide array of specification options, enabling lighting designers to configure nearly every component to suit the precise needs of each space. The result is a tailored luminaire that balances high-performance capabilities with refined aesthetics.
Constructed from durable aluminum with a smooth, powder-coated finish, TUNNEL features steel cable suspension for a clean floating appearance. A silver braided power cable adds to the fixture’s polished look. Its 2.4-inch-wide opal acrylic diffuser ensures even light distribution while contributing to the fixture’s slim profile. TUNNEL’s performance is equally impressive, delivering high lumens per watt based on 4000K at 80+ CRI, making it a strong solution for both visual comfort and energy efficiency.
TUNNEL can be integrated into a Power over Ethernet (PoE) system, allowing seamless incorporation into modern smart building infrastructures. For more advanced lighting solutions, it is compatible with circadian lighting systems like BIOS, and also supports RGBW and Tunable White technology with a range from 2700K to 6500K (factory consultation required). The luminaire houses high power factor (HPF) electronic drivers for 120-277V and 347V (EU-240V), which are integral to the fixture housing.
Flexibility extends to fixture lengths, which are available in 1-inch increments, offering maximum adaptability for design configurations. TUNNEL is built to last, boasting a reported L70 of over 60,000 hours and an estimated L70 of more than 165,000 hours at 25°C, operating at 2000 lumens per foot (6000 lumens per meter).
The luminaire includes an optional integral emergency lighting system, providing 1.5 hours of backup (3 hours for EU), with a self-contained module, NiCad batteries, and a test switch and LED indicator (North America only). It supports a broad range of lighting control systems including Avi-On, Casambi, Enlighted, Lutron Vive, nLight, NX Lighting Controls, Osram, and Philips—ensuring compatibility with your preferred smart control platform.
TUNNEL is damp rated for indoor use and mounts directly over standard junction boxes. It is available with seismic bracing kits to meet code compliance in applicable regions. With its luxurious design, outstanding functionality, and extensive configurability, TUNNEL is an ideal lighting solution for commercial, institutional, and high-end interior environments. A US design patent is currently pending, further affirming its originality in the marketplace.
