FEATURES & SPECIFICATIONS
INTENDED USE — The 8" Wafer™ LED square recessed downlight with remote driver box combines
high quality light output and efficiency while eliminating the housing for competitive affordability. This
innovative wafer-slim Type IC design allows easy installation for new construction or remodel from below
the ceiling without the requirement of a housing. The LED module maintains at least 70% light output
for 50,000 hours. These Wafer LED downlights are intended for basements,soffits,entryways,stairwells,
corridors, hospitals, multi-family, and commercial projects.
CONSTRUCTION — IC rated driver and fixture - approved for direct contact with insulation. Aluminum die
cast outer frame. Durable, powder coat paint to prevent rust. Square fixture with integral edge-lit LED's.
Steel spring clip for easy installation. Plenum rated cable connector to connect from module to remote
driver box. Isolated driver integrated inside steel remote box with four 7/8" knockouts with slots for pryout.
Suitable for pulling wires with the 12 cubic-inch wiring compartment to accommodate up to (8) 14 gauge
insulated conductors, or (6) 12 gauge insulated conductors; making the Wafer LED Downlights much easier
to wire in 2in/2out (plus ground) daisy-chain applications and contractor friendly.
INSTALLATION — Ideal for shallow ceiling plenum; no housing required. Steel spring clip for easy
installation. 8" cut out template is provided to ensure the correct size hole cut into ceiling for proper
installation of the trim. Size of hole should not exceed 8 1/4 inches for this product. Suitable for installation
in t-grid and drop ceiling applications. 2" plenum space required for installation of the remote driver box.
OPTICS — Edge-lit LED technology uses light guided plate to distribute light. Polycarbonate lens provides
even illumination throughout the space. Utilized 3000K, 3500K, 4000K, and 5000K color temperature LEDs.
ELECTRICAL — Multi-volt (120-277V, 50/60Hz) proprietary remote LED driver/splice box, with two
(2) additional low-voltage wires for 0-10v dimming, down to 10% (depending on dimmer model and
application). High efficient driver with power factor > 0.9. Ambient operating temperature: -40°F (-40°C)
to +104°F (+40°C). Replaces 100W incandescent.
