The narrow 1.5-inch aperture ‘X’ shaped recessed LED luminaire is designed to integrate seamlessly with ceilings in a variety of mounting styles, delivering a clean and unobtrusive aesthetic. Available with flush and Batwing lenses, the fixture ensures visual comfort while providing uniform illumination and precise brightness control. Configurable point sources offer beam spreads ranging from narrow to wide flood, from 21° to 53°, enabling tailored lighting designs. When paired with other Seem 1 luminaires, this recessed solution maintains a cohesive and harmonious visual environment, making it ideal for modern commercial interiors.
Performance is enhanced through proprietary linear LED boards that produce continuous lines of light without visible pixels or shadows. Direct lensed illumination and individually specified point sources are carefully controlled to achieve optimal light distribution on work planes, walls, and ceilings, delivering a balanced mix of visual comfort and high performance. This design ensures consistent lighting quality across the entire space while supporting a variety of architectural layouts.
The luminaire supports diverse applications with 4-foot and 6-foot diameter configurations, making it an excellent choice for commercial spaces that require ambient illumination combined with a distinctive aesthetic. It makes a strong visual statement in amenity areas, lounge spaces, corridors, offices, educational facilities, hospitality venues, and medical environments. Deeply regressed louver cells provide a 60° cut-off from the light source, enhancing visual comfort, while direct Lambertian or Batwing light distributions create a smooth, glare-free illumination. Point source outputs can be selected to meet the unique requirements of each installation.
Constructed from extruded aluminum with cast aluminum end caps, the luminaire weighs no more than 21 pounds. Reflectors are fabricated from 22-gauge steel and finished with a high-reflectance white powder coat, paired with a .07-inch thick extruded acrylic lens featuring a frosted finish. This combination provides consistent, high-quality light while maintaining a sleek, architectural profile. The LED system incorporates premium modules mounted on a robust platform with excellent thermal management, ensuring uniform light distribution and long-term performance. LED modules and drivers are replaceable from below, and the fixture maintains color accuracy within <3 SDCM. Available color temperatures include 2700K, 3000K, 3500K, and 4000K with both 80 and 90 CRI options, while high-CRI options maintain a cyanosis observation index (COI) of 3.3 or less.
The luminaire is pre-wired with factory-installed branch circuit wiring and over-molded quick connects. The standard 120-277V constant current driver includes 0-10V analog dimming and a power factor exceeding 0.9. For modern networking integration, the fixture is compatible with Power over Ethernet (PoE) systems using standard low-voltage wiring, although each section requires an independent PoE node and power feed. Emergency battery output provides 10 watts for 90 minutes, suitable for mounting heights up to 18.5 feet.
UL and cUL listed, the fixture is suitable for dry or damp indoor locations. The housing is finished with a durable polyester powder coat applied over a multi-stage pre-treatment, with the standard canopy and cord supplied in white. The luminaire demonstrates exceptional lumen maintenance, with L70 values reported at over 61,000 hours for lensed sources, 54,000 hours for louvered sources, and 55,000 hours for point sources. Calculated L70 lifespans extend to 470,000, 138,000, and 226,000 hours respectively, ensuring consistent illumination and long-term reliability.
Available nominal sizes include 4-foot diameters with two arms and 6-foot diameters with three arms. Lumen output ranges from 1000 to 5000 lumens for the 4-foot configuration and 4500 to 7500 lumens for the 6-foot option. Shielding options include Batwing and Flush lenses, with circuit and voltage configurations accommodating standard 120/277V or 347V systems, as well as low-voltage PoE operation. Dimming and control compatibility includes 0-10V, Lutron Hi-Lume EcoSystem, and DALI, offering flexibility for various commercial lighting systems.
Installation options include mud-in trimless ceilings, with factory-configured Chicago Plenum, emergency circuits, and battery packs available. Custom New York City flex whip configurations and extended cabling provide additional installation flexibility. The luminaire’s matte white finish complements a wide range of interiors, delivering a modern, high-performance lighting solution that blends seamlessly with contemporary architectural design.
