CONSTRUCTION
Rigid steel housing includes typical recycled
content of 40%.
CONNECTIONS
Secure, simple housing connections provide
continuous rows where desired.
MOUNTING
Plaster Flange (P) mounting as described in
Housing and Trim section. Microlyne® Recessed
is also available in Grid or T-Bar applications
or Flange (F) for drywall applications where
housing trim is desired to complete the finished
appearance as a complementary visible framing
mechanism. See separate specification sheets.
REFLECTOR
White high reflectance internal reflector.
SHIELDING
Shielding is provided for single or continuous row.
Options match across entire Microlyne® family.
OA - Opal Acrylic lens emphasizes the narrow
rectilinear shape by creating a pleasant glow of
white along the underside of the housing.
WCB – White Cross Baffle emphasizes linearity
with a crisp, clean bladed appearance.
M4R - 95% Reflective Specular Aluminum louver
combines glare control and performance with a
high tech appearance.
MA - Matte anodized louvers incorporate
an attractive but subtle grain pattern which
minimizes the visibility of fingerprints and
construction dust without sacrifice to aesthetic
qualities.
HEP - High efficiency parabolic specular louver
maximizes downlight for enhanced efficiency
where maximum light output is the primary
concern.
DISTRIBUTION
Symmetric downlight distribution is standard and
used for general purpose lighting where uniform

ELECTRICAL
—All luminaires are built to UL1598 standards and
bear the appropriate cUL or CSA labels. Damp
location listed.
—Quick connect plugs standard.
FINISH
Recessed housing and any visible flange trim is
standard white. Zet Silver and additional colors
and finishes optional.
CONTROLS COMPATIBILITY
Controls compatible. When used with occupancy
sensors, most lamp vendors recommend program
start ballasts (EP) to extend lamp life. Common
control schemes: wiHUBB enabled (WIH)
switching L/R, 0-10V dimming ballast (ED), Step
Dimming ballast (ESD), wiHUBB enabled (WIH).
Compatibility with specific control is by others.
wiHUBB antenna will be visible.
PLASTER FLANGE HOUSING & TRIM
Fine detail corrosion resistant feathering mud
wings extend a full 1½” on all sides of the housing
to allow consistent, attractive ceiling finish all
the way around housing. Maximized feathering
edge trims reduce plaster gaps, sags, bumps
and depressions associated with inconsistent
mud drying time. Wing hangers snug firmly to
ceiling structure elements such as C-channel or
permanent frame box (both by others) using a
simple twist. Design provides ease of installation
and unparalleled finished appearance.
