The narrow 1.5-inch aperture ‘X’ shaped suspended LED luminaire delivers a sophisticated direct and indirect lighting solution, seamlessly integrating into ceilings for a clean, unobtrusive aesthetic. Designed with configurable visual features, this luminaire includes illuminated end caps and point sources, while Flush and Batwing lenses provide superior visual comfort with uniform illumination and precise brightness control. Continuous illumination extends from the bottom lens to the lit end cap, creating a cohesive and elegant appearance that harmonizes perfectly when paired with other Seem 1 luminaires in a space. Point sources are available with narrow to wide flood beam spread options ranging from 21° to 53°, allowing tailored lighting for varied spatial requirements.
Performance is optimized through proprietary linear LED boards that create seamless lines of light without pixels or shadows. Each luminaire is individually specified and controlled, offering precise direct and indirect lensed illumination, point sources, and louvers to ensure optimal lighting on work planes and ceilings. These features allow the luminaire to deliver both functional and aesthetic lighting, suitable for environments where visual comfort and design cohesion are essential. The system supports 4-foot and 6-foot diameter units, making it an ideal solution for commercial applications requiring ambient illumination and a differentiated architectural statement, including amenity areas, lounge spaces, corridors, offices, educational facilities, hospitality venues, and medical environments.
Constructed from extruded aluminum with cast aluminum end caps, the luminaire is lightweight, not exceeding 21 pounds, while maintaining robust structural integrity. Reflectors are fabricated from 22-gauge steel finished in high-reflectance white powder coat, and an extruded acrylic lens with a .085-inch frosted finish ensures a soft, diffused glow. Deeply regressed louver cells provide a 60-degree cut-off from the light source, enhancing visual comfort. The luminaire is compatible with Power over Ethernet (PoE) lighting systems via standard low-voltage wiring, enabling modern networked lighting integration. Available in The Naturals finish series, this luminaire offers biophilic-inspired aesthetics with 100% low-VOC vinyl options for environmentally conscious designs.
The LED system utilizes premium LEDs mounted on a robust platform to ensure excellent thermal management and uniform light appearance. Color temperatures are available in 2700K, 3000K, 3500K, and 4000K, with both 80 and 90 CRI options. High-CRI configurations of 3500K and 4000K feature a cyanosis observation index (COI) of 3.3 or less, ensuring accurate color rendering. LED modules and drivers are replaceable from below, and color accuracy is maintained at less than 3 SDCM. Lumen maintenance is impressive, with lensed sources reporting L70 at over 61,000 hours and calculated at 470,000 hours, louvered sources at over 54,000 hours (calculated 138,000 hours), and point sources at over 55,000 hours (calculated 226,000 hours), guaranteeing long-term performance and reliability.
Electrical components are pre-wired with factory-installed branch circuit wiring and over-molded quick connects. A standard 120-277V constant current driver includes 0-10V analog dimming, with a power factor exceeding 0.9. PoE integration requires an independent node and power feed for each luminaire section. Emergency lighting is supported with a 10-watt battery providing 90 minutes of operation, suitable for a maximum mounting height of 18.5 feet. The luminaire is UL and cUL listed, suitable for dry or damp indoor locations, and finished with a polyester powder coat applied over a multi-stage pre-treatment. Standard canopy and cord finishes are white, with The Naturals series offering low-VOC vinyl finishes.
The luminaire is offered in multiple diameters, with 4-foot units featuring 2-foot arms and 6-foot units featuring 3-foot arms. Shielding options include Batwing Optic top/Flush Lens bottom, Batwing Optic top/Batwing Lens bottom, and Dust Cover top with Flush or Batwing Lens bottom. Lumen outputs for 4-foot diameters range from 1000 to 9000 lumens, while 6-foot diameters range from 1500 to 13,500 lumens. Direct and indirect lensed distributions are configurable to meet specific lighting requirements, with direct lensed outputs supporting up to 5000 lumens for 4-foot units and 7500 lumens for 6-foot units, and indirect outputs starting from 2000 and 3000 lumens respectively. Color temperatures are customizable between 2700K and 4000K with both 80+ and 90+ CRI options.
The luminaire supports single and dual circuits, allowing independent control of direct and indirect sources. Voltage options include 120/277V universal, 347V (LD1 driver only), and low-voltage PoE-compatible configurations. Dimming and control options include 0-10V at 10% or 1%, Lutron Hi-Lume EcoSystem at 1%, and DALI at 1%. Mounting options include 48-inch and 96-inch single suspension cables, as well as 24-inch, 48-inch, and 96-inch multi-point suspension cables, with customization available for sloped ceilings. Factory options include black cord, lit end caps, emergency circuits, emergency battery packs, and a range of housing finishes including matte black, titanium silver, and matte white.
