The late John E. Flynn, Professor of Illumination
Studies at Pennsylvania State University, in his
research on the psychology of lighting, identified that
wall lighting improves visual clarity, enhances
perceived spaciousness, and adds a sense of relaxation.
Studies by the National Research Council of Canada
confirm Flynn's work. People consistently rate rooms
with wall lighting as brighter and more pleasant.
These psychological studies provide important insight
for lighting design, as we strive to create lighting
schemes that are appealing and comfortable.

Beyond the Aesthetics
Litecontrol's Wall/Slot systems are engineered to
meet three objectives:
■
Ease of installation with a unique
wall mounting rail.
■
Design flexibility through options such
as various baffles, baffle positions
and lamping options.

See the light, not the fixture
Architectural Details
The clean appearance is carried through the
design of corners and connectors, completing the
architecturally appealing system. Wall/Slot-2000
is particularly appropriate for long corridors,
large conference rooms, courtrooms, high-ceiling
spaces, bathrooms - any space with a ceiling slot
that can be easily viewed. Lamps are concealed
at all viewing angles, without the need for a
baffle. Wall/Slot-2000 is equally suited to small

The Wall/Slot-2000 pushes light out
into the room while evenly lighting
the wall.
With the PR reflector, additional
luminance further down the wall is
achieved, without visible reflectors
or hardware.
Alternative products put bright light
only onto the upper half of the wall and
some light into the room.

Wall/Slot-II
The original perimeter system
Architectural Details
Three optional baffle positions allow for any ceiling
effect desired: directly under lamps for “floating ceiling”
appearance; slightly regressed from ceiling; or flush
with ceiling for an uninterrupted ceiling plane effect.
With a variety of diffusers and baffles available and the
capability to accommodate all ceiling types, Wall/Slot-II
can achieve the desired look in any space. Mitered
corner baffles and a unique splining system allow for a
continuous slot appearance throughout a space.

Wall/Cove
Wall lighting for spaces with low ceilings
Architectural Details
Wall/Cove attaches to the wall at the ceiling. Finished in
white, it virtually disappears into the ceiling because of
its shallow 2 7/8" depth. When finished in a color, it
becomes an architectural accent. Wall/Cove is often used
with a fascia to match or complement other architectural
elements. The fascia serves to shield the fixture and
lamps from normal viewing angles, to achieve a concealed
cove effect. The specular reflector option in the one-lamp
fixture is an energy-effective option for lighting bulletin
boards or chalkboards.
Unique Features
■ Designed for spaces that require
wall illumination, but do not have
the plenum space to use a
traditional Wall/Slot.
■ Available with several optional baffles
or diffusers.

■ For continuous row wiring, knockouts
are also provided on each end header.
