FEATURES & SPECIFICATIONS
INTENDED USE —The BLC troffer delivers soft, glare-free, ambient lighting in a popular center-basket
design. The slim profile of the luminaire, coupled with energy-saving LED technology make the BLC an ideal
choice for renovation or new construction. The BLC 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 highly reflective paint for improved aesthetics and
increased light diffusion.End plates contain easy-to-position integral T-bar clips for securely attaching the
luminaire to the T-grid. For additional T-grid security, optional screw on T-bar clips are available. Diffusers
are extruded from impact modified acrylic for increased durability. LED boards and drivers are accessible
from the plenum.
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. High performance extruded acrylic diffusers conceal LEDs
and efficiently deliver light in a volumetric distribution.
ELECTRICAL — Long-life LEDs, coupled with high-efficiency drivers, provide superior quantity and quality
of illumination for extended service life. 80% LED lumen maintenance at 60,000 hours (L80/60,000). 0-10
volt dimming driver. Dims to 10%. Driver disconnect provided where required to comply with US and
Canadian codes.
INSTALLATION — With a depth of only 2-3/8", the BLC makes for an easy installation, especially in restrictive
plenum applications. The BLC fits into standard 15/16" and narrow 9/16" T-grid ceiling systems. Battery
packs are available for field installation. Suitable for damp location.
For recessed mounting in hard ceiling applications, Dry wall Grid Adapters (DGA) are available as an accessory.
