Silhouette, an innovative linear lighting
system that incorporates the latest T5
lamp technology in a compact luminaire.
SA SB SC
The system includes both individual and joiner luminaires. When
the joiners are connected together
to create a continuous run the
suspension points are on 48" and
96" centers.
All fixtures shown in this matrix
are individual luminaires.

Silhouette – The System
Silhouette installed in continuous rows uses visually appealing and mechanically simple joiners forming hairline joints without visible fasteners.
(Luminaire pictured above shows an 8' joiner module joined with a 4' joiner module and power feed end set.)
Combining minimal scale with elegant shapes, the Silhouette
System offers an unparalleled number of design and light
configuration options. Easily adaptable, the linear lighting
system provides high quality illumination in a choice of flexible
configurations, with a diminutive profile that adds a new level
of style to interiors.
Silhouette features modular systems that join together to create
a variety of configurations and patterns. This allows the designer
maximum flexibility in achieving an end result uniquely suited to a
space. The Silhouette System comes with three basic light distribution options – indirect, indirect/direct and direct.
The Silhouette System allows the designer a wide range of layout
options...whether it be straight runs, rectangles, nested patterns
or ladder configurations. The combination of minimal housing
dimensions and optical performance provides a level of design flexibility not attainable with many larger luminaires.
The slim dimensions of Silhouette are achieved by a compact extrusion which houses the T5 lamp. Precisely engineered reflectors
assure high efficiency and lighting design integrity. Factory prewired modular sections with quick connectors allow fast and easy
adjustable mounting. Continuous rows and patterns have support
spacing of 48" and 96" allowing ease of installation. A single
screw, draw-tight joiner connection creates a hairline joint for a virtually seamless appearance.
Individual End Detail
Individual luminaires, in 4 and 8 foot lengths, have
a flush end cap where the extruded housing and
shielding are aligned at both ends.
Run End Detail
Joiner luminaires create continuous runs and patterns.
They have a continuous housing with shielding that is
spaced about an inch apart to create a unique look.

Silhouette – Indirect/Direct
Silhouette Indirect/Direct Series pro-
vides a combination of indirect and
direct lighting with high efficiency
and visual comfort. The series is
suited to spaces where both indirect
and direct lighting components are
desired. The pierced steel and opal
diffuser give Luminaire SD a visual
accent of 20% direct lighting while
providing all the benefits of indirect
lighting. For applications that require
a higher degree of direct lighting,
Luminaire SE offers 29% direct light.
Opal acrylic combined with the small
extruded housing provides approxi-
mately 53% direct lighting in
Luminaire SF. Whichever indirect/
direct version you specify, you’ll be
impressed not only by the lighting,
but also by the beautiful way in
which the lighting
is delivered.
