performance.

The STACK lay-in delivers glare-free, ambient lighting in a popular center-basket design. 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.
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.
