PRODUCT FAMILY SPECIFICATIONS
INTENDED USE
Available in 2x2 and 2x4 configuration, STACK provides both functionality and efficiency. STACK is the ideal choice for many recessed commercial applications. The wide center basked and curved matte reflector allow STACK to deliver a high quality of light while maintaining optimal performance.

• Less than 2" in depth.
• A high level of configurability allows you to choose the perfect solution for your space.
• Available 0-10v dimming to 1%.
• Long-life LEDs deliver 80% lumen maintenance at 60,000 hours

The STACK lay-in delivers low glare, ambient lighting in a popular center-basket design. A typically configured STAK features a Unified Glare Rating (UGR) starting at 16, UGR data available on page 6. The slim profile of the luminaire, coupled with energy-saving LED technology make STACK an ideal choice for renovation or new construction. The STACK lay-in offers a high-quality, cost-effective LED lighting solution for schools, offices, retail, healthcare facilities and other commercial spaces. CONSTRUCTION — The reflector is finished with a glare reducing matte white paint for improved aesthetics and increased light diffusion. End plates contain easy-to-position clips allowing the luminaire to be securely attached to the T grid. Diffusers are extruded from impact modified acrylic for increased durability. LED boards are accessible from the room-side, and drivers are accessible from the plenum. Integrated Sensor (nLight Wired Networking): This sensor is nLight-enabled, meaning it has the ability to communicate over an nLight network. When wired, using CAT-5 cabling, with other nLight-enabled sensors, power packs, or WallPods, an nLight control zone is created. Once linked to a Gateway, directly or via a Bridge, the zone becomes capable of remote status monitoring and control via SensorView software. Integrated Smart Sensor (nLight Air Wireless Platform): The RES7 sensor is nLight AIR enabled, meaning it has the ability to communicate over the wireless nLight control platform. It is available with an automatic dimming photocell, and either a digital PIR or a microphonics (PDT) dual technology occupancy sensor. It pairs to other luminaires and wall switches through our mobile app, CLAIRITY+, which allows for simple sensor adjustment Integrated Wireless Sensor (single room control): Sensor Switch VERTEX JOT or JOTVTX15 luminaireembedded occupancy and ambient light sensor allows the luminaire to power off when the space is unoccupied or when enough ambient light is entering the space. See page 7 for more details on the integrated wireless sensor.

INSTALLATION
With a depth of only 1.9", STACK makes for an easy installation, especially in restrictive plenum applications. STACK fits into standard 15/16" and narrow 9/16" T-grid ceiling systems. Suitable for damp location.

ELECTRICAL
Long-life LED's, coupled with high-efficiency drivers provide superior quality of light and an extended service life. 80% LED lumen maintenance at 60,000 hours (L80/60,000). 0-10 volt dimming driver, dims to 1%.

OPTICS
Volumetric illumination is achieved by creating an optimal mix of light to walls, partitions and vertical and horizontal work surfaces – rendering the interior space, objects and occupants in a more balanced, complimentary luminous environment. A high performance acrylic diffuser conceals LED's and efficiently delivers light in a volumetric distribution.
