The narrow 1.5-inch aperture Y-shaped suspended direct/indirect LED luminaire is designed as a striking architectural feature while maintaining a clean, minimalist presence. Its distinctive configuration offers lit end caps for continuous illumination from lens to edge, as well as optional integrated point sources that expand design flexibility. Flush and Batwing lens options ensure uniform brightness control and enhanced visual comfort, while point source modules deliver precise beam spreads ranging from narrow 21° to wide 53°. When paired with other luminaires in the family, the fixture provides a cohesive aesthetic that enhances modern interiors.
Built for high performance, the luminaire uses linear LED boards to deliver seamless lines of light without visible pixels or shadows. Both the direct and indirect distributions can be individually specified and controlled, ensuring balanced illumination across work planes and ceilings. The optical system is engineered for optimal uniformity, with deeply regressed louvers that provide 60° cut-off to reduce glare and improve comfort in demanding environments.
The fixture supports a wide range of applications, available in 4-foot and 6-foot diameters to suit various scales of installation. It is particularly well-suited for commercial interiors that require both high-quality ambient illumination and a bold visual statement. Whether used in amenity spaces, lounges, offices, hospitality environments, educational facilities, or healthcare settings, the luminaire serves as both a lighting tool and a design centerpiece.
Constructed from extruded aluminum with cast aluminum end caps, the housing is lightweight yet durable, with a maximum weight of 16 lbs. Reflectors are fabricated from 22-gauge steel finished in high-reflectance white powder coat, while the extruded acrylic lens is 0.085 inches thick with a frosted finish. Multiple shielding options, including Batwing and Flush lens combinations, provide flexibility for different visual and architectural requirements.
The luminaire incorporates a proprietary LED system with premium diodes mounted on a robust platform for superior thermal management. This system ensures consistent performance and longevity, with color accuracy maintained below 3 SDCM. Standard color temperatures include 2700K, 3000K, 3500K, and 4000K, available in both 80 and 90 CRI options. For specialized healthcare applications, 3500K and 4000K options with CRI above 90 achieve a cyanosis observation index (COI) of 3.3 or less. Both LED modules and drivers are replaceable from below for serviceability.
The electrical system comes pre-wired with factory-installed branch circuit wiring and over-molded quick connects. A standard 120-277V constant current driver with 0-10V dimming is included, and the luminaire is PoE compatible, allowing integration with Power over Ethernet lighting systems through low-voltage wiring. PoE installations require an independent node and power feed for each luminaire section. Emergency operation is supported with a 10-watt battery option that provides 90 minutes of illumination at mounting heights up to 18.5 feet.
Certified to UL and cUL standards, the luminaire is suitable for dry or damp locations in indoor environments. The housing finish is a polyester powder coat applied over a multi-stage pre-treatment process, with options including Matte White, Black, Titanium Silver, and antimicrobial finishes. Additionally, The Naturals series of low-VOC vinyl finishes is available to bring biophilic-inspired aesthetics into interior spaces.
Long-term reliability is supported by excellent lumen maintenance values. Lensed sources achieve an L70 of over 61,000 hours reported and 470,000 hours calculated, while louvered sources and point sources deliver similarly robust lifespans. Various lumen outputs are available, ranging from 750 to 7500 lumens for the 4-foot configuration and from 1125 to 10,125 lumens for the 6-foot configuration, accommodating both direct and indirect distributions.
Flexible mounting systems further extend the luminaire’s versatility, with single- and multi-point suspension options in varying cable lengths. Power cords may be positioned at the fixture intersection or at the ends, with finishes coordinated to match canopy selections. Additional factory options include lit end caps, emergency circuits, and custom cord colors, ensuring that the luminaire can be tailored to both functional and aesthetic requirements.
