The STACK Switch troffer delivers glare-free, ambient lighting in a popular center-basket design. The slim
profile of the luminaire, coupled with energy-saving LED technology make the STACK Switch an ideal
choice for renovation or new construction. The STACK Switch troffer 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 integral T-bar clips to securely
attach the luminaire 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.
INSTALLATION  With a depth of only 1.9", the STACK Switch makes for an easy installation, especially
in restrictive plenum applications. The STACK Switch 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 10%.
Lumen and Color Switching: Integrated lumen and color switching module is easily accessible
and mounted on the driver box on the back of the fixture. Simply adjust the toggle switch
for low, medium, and high lumen and color settings.
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.
