• Long-life LEDs deliver 80% lumen maintenance at 60,000 hours

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.
