The narrow 1.5-inch aperture Y-shaped recessed LED luminaire is designed to integrate seamlessly with ceilings, offering a clean and unobtrusive aesthetic that elevates architectural spaces. Its sculptural form is available in a variety of mounting styles and can be configured with eye-catching features such as louvers and point sources. Flush and Batwing lenses enhance visual comfort while ensuring uniform illumination and effective brightness control. Point sources provide flexibility with beam spreads ranging from narrow 21° to wide 53°, making the fixture highly adaptable. When paired with other luminaires from the same family, it creates a cohesive and visually striking aesthetic throughout a space.
This recessed system delivers uninterrupted lines of light, thanks to its linear LED boards that eliminate visible pixels and shadows. Designers can specify and control direct lensed illumination as well as integrated point sources independently, enabling precise and optimal lighting design. Available in 4-foot and 6-foot diameters, the luminaire supports diverse applications, from ambient illumination to statement lighting. It is particularly well suited for amenity areas, lounges, corridors, offices, educational institutions, hospitality venues, and medical facilities, where both performance and a differentiated look are desired.
Crafted from extruded aluminum with cast aluminum end caps, the housing is engineered for strength while maintaining a lightweight design that does not exceed 16 pounds. The optical system includes deeply regressed louver cells offering 60° cut-off for superior glare control and visual comfort. Lambertian or Batwing light distributions enhance uniformity, while point source options allow for tailored output levels to suit specific applications. The system is also PoE compatible, integrating easily with Power over Ethernet lighting systems via low-voltage wiring.
The proprietary LED system employs premium diodes mounted on a robust platform for superior thermal management and consistent performance. LEDs are carefully placed to ensure a uniform appearance, with available color temperatures of 2700K, 3000K, 3500K, and 4000K in both 80 and 90 CRI options. For environments requiring clinical precision, the 3500K and 4000K models with CRI above 90 maintain a cyanosis observation index (COI) of 3.3 or less. Modules and drivers are replaceable from below, with color accuracy maintained at <3 SDCM.
The optical components include reflectors fabricated from 22-gauge steel with a high-reflectance white powder-coated finish and extruded acrylic lenses with a frosted surface to ensure smooth, diffused output. Electrical performance is equally robust, with factory pre-wired branch circuit connections, over-molded quick connects, and a 120-277V constant current driver with 0-10V dimming capability. The system is also available with low-voltage or advanced control compatibility, including Lutron EcoSystem and DALI options.
Emergency performance is supported with a 10-watt emergency battery that provides 90 minutes of output, accommodating mounting heights up to 18.5 feet. Reliability is further reinforced by UL and cUL listings for dry and damp locations, ensuring suitability for indoor applications.
Durability is enhanced by a polyester powder coat finish applied over a multi-stage pre-treatment, with standard canopy and cord supplied in white. Lumen maintenance is industry-leading, with lensed sources achieving reported L70 at over 61,000 hours and calculated performance extending to 470,000 hours. Louvered and point sources also demonstrate impressive longevity, maintaining consistent illumination performance for decades of use.
Altogether, this Y-shaped recessed LED luminaire combines precision engineering, advanced optics, and refined aesthetics to provide a versatile lighting solution that enhances architectural spaces while delivering long-lasting performance.
