Slim Profile: Ideal for renovation or new construction.
Cost-Effective: Suitable for schools, offices, retail, healthcare, and other commercial spaces.

Construction

The reflector is finished with a glare-reducing matte white paint for improved aesthetics and light diffusion. End plates have easy-to-position clips for secure attachment to T-grid ceilings. Diffusers are made from impact-modified acrylic for durability. LED boards are accessible from the room side, and drivers are accessible from the plenum.

Standalone Embedded Controls: SensorSwitch luminaires are factory-equipped with sensors/controls, simplifying installation and reducing costs.
Networked Embedded Controls: nLight luminaires support Luminaire Level Lighting Controls (LLLC), also factory-equipped for simplified installation and code compliance.

Installation

With a depth of only 1.9 inches, STACK is easy to install, especially in restrictive plenum applications. It fits standard 15/16" and narrow 9/16" T-grid ceiling systems and is suitable for damp locations.

Electrical

Features long-life LEDs and high-efficiency drivers for superior light quality and extended service life. Offers 0-10 volt dimming down to 1%.

Optics

Achieves volumetric illumination by optimizing light distribution to walls, partitions, and work surfaces, creating a balanced and complimentary luminous environment. A high-performance acrylic diffuser conceals LEDs and efficiently delivers light volumetrically.
