Lowprofile CD7
Sleek and compact,
Lowprofile CD7
makes a dynamic
design statement
used individually
or in graceful
linear runs.
When suspended, the Lowprofile
CD7 appears to float in the
environment. The bold design
and full range of functions make
the Lowprofile CD7 ideal for
large open areas as well as
contained spaces. Its attractive
housing is made up of two
die cast end caps connected by
high quality aluminum extrusions.
Light shielding is by means of
a high performance semi-specular
parabolic louver or acrylic
prismatic lens.

Lightolier Lighting Systems
Lightolier Lighting Systems are modular lighting systems that offer a wide selection of
geometric shapes, architectural profiles, scales and finishes.
These quality materials combined with a highly efficient reflector
system, make the Lowprofile CD7 ideal for settings requiring
generous overall illumination as well as those where a soft ambi-
ence is to be combined with controlled task lighting. The Lowprofile
is designed to provide both superior photometric performance in
either indirect/direct or direct light distributions. Whether stem
suspended, cable suspended or surface mounted, the Lowprofile
CD7 provides high performance in an attractive package.
