The narrow 1.5-inch aperture recessed direct LED luminaire offers a sophisticated and highly configurable solution for modern commercial lighting. Its design features deeply regressed louvers, lensed illumination, and solid faceplates, creating a clean and unobtrusive aesthetic that integrates seamlessly with a variety of ceiling types. Flush and Batwing lens options provide enhanced visual comfort, uniform illumination, and precise brightness control, while point sources are available in beam spreads ranging from 20° to 67°, including a Louver Mixing Chamber option at 68°. A diversity of louver finishes allows the light to be tailored to the desired effect, from nearly invisible sources that transition sharply to the surrounding space, to warmly illuminated cells that offer a smooth, inviting glow.
Performance of the luminaire is optimized through separate specification of lumen outputs for lensed and louvered illumination, enabling precise lighting scenes and control over individual light sources. Linear LED boards produce seamless lines of light without pixels or shadows, while the internal alignment plate and joining mechanisms ensure stable positioning and easy installation in continuous runs. This system allows for highly flexible configurations and tailored output levels, supporting both focused task lighting and ambient illumination, depending on the application requirements.
The luminaire supports both individual units and continuous runs in standard or customized configurations using a combination of louvers, lenses, and solid faceplates. Its versatile mounting options facilitate integration into a wide range of specialty ceilings, making it an ideal choice for corporate offices, conference rooms, corridors, recreational spaces, educational facilities, healthcare environments, retail spaces, and hospitality venues. The highly configurable system allows for self-service creation of custom lengths and arrangements with standard lead times.
The LED system incorporates proprietary linear modules with premium LEDs mounted on a robust platform to ensure excellent thermal management. LEDs are positioned for uniform appearance and consistent output, with color temperatures available in 2700K, 3000K, 3500K, or 4000K and CRI options of 80 or 90. Modules and drivers are replaceable from below, and color accuracy is maintained at less than 3 SDCM. The housing is constructed from a single piece of extruded aluminum with 20-gauge steel end caps, designed for new construction applications. Units weigh approximately 15 lbs for an 8-foot length and are suitable for wood ceilings (XFW), with Type IC applications available upon consultation.
Optical performance is enhanced by deeply regressed louver cells that provide a 60-degree cut-off from the light source, ensuring visual comfort. Lensed reflectors are fabricated from 24-gauge steel with a high-reflectance white powder coat finish, and the extruded acrylic lens is .085 inches thick with a frosted finish, providing uninterrupted illumination in runs up to 8 feet. Louvers and lenses can be configured in various increments to create custom lengths and visual effects, supporting both fully louvered or mixed arrangements along the run.
Electrical systems are 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, with a power factor greater than 0.9. Emergency backup provides 10 watts for 90 minutes, with maximum mounting heights of 26.4 feet for louvered sources and 18 feet for lensed sources. All luminaires are UL and cUL listed for dry or damp indoor locations.
The luminaire is finished with a durable polyester powder coat applied over a multi-stage pre-treatment, providing both aesthetic appeal and long-term protection. Lumen maintenance is exceptional, with linear sources reporting L70 at greater than 61,000 hours (calculated L70 at 470,000 hours) and L90 at 115,000 hours, while louvered sources report L70 at over 54,000 hours (calculated L70 at 138,000 hours) and L90 at 43,000 hours. The system supports a variety of shielding options, including Batwing lens with louver, Flush lens with louver, solid faceplate with louver, and fully louvered configurations. Louver lengths can be customized at start, middle, or end of runs, allowing maximum flexibility for continuous or segmented installations.
Lumen output options range from 250 to 1000 lumens per foot, ensuring precise tailoring of light levels to meet the unique needs of commercial spaces. The combination of high-performance optics, customizable louver finishes, and versatile mounting and shielding options makes this narrow 1.5-inch recessed direct LED luminaire an ideal solution for designers and facility managers seeking both aesthetic elegance and superior lighting performance.
