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.
