PSL system—light trespass shield
PSL system—Glare Guard
GLARE GUARD
Glare guards provide increased
visibility for the driver. Excessive
direct glare, a function of lamp
wattage, fixture placement and
distribution, can cause discomfort
and disability glare, a dangerous
distraction for drivers and
pedestrians. PSL glare guards
diminish this distraction for drivers,
increasing their visual comfort and
visibility.
Field-installable internal glare guards
redirect a 60º horizontal segment of
light emitted towards the driver into
the pedestrian walkways and driving
stalls. These specular, faceted inserts
redirect light around the lamp to
minimize the arc tube voltage rise
through the upper prism structures
and the lower concave prism profile.
They clip into preset labeled
locations and lock into place without
tools, yet cannot be removed during
normal maintenance. They are ideal
accessories for providing an
optimized driving environment.
LIGHT TRESPASS SHIELD
Light trespass shield cuts off any
illumination towards the exterior of
the parking garage. Designed into 90º
horizontal quadrants, they are field
installable and remain in place during
maintenance. These louvers are
designed to cutoff the vertical angles
of light above 57º and can be used
in combination with glare guards and
in any position depending on a fixture’s
orientation.
Glare guards are ideal for single- and double-row installations. The 60º segments lock into preset locations without tools and
can be installed at any time. The light is redirected into the walkways and stalls. Glare guards may even be installed in pairs
for two-way traffic areas for complete driver light control.
Single-Row Configuration
Double-Row Configuration
Light Trespass Shields (LTS) are designed to provide 57º cutoff, the angle found in the double-row system between the fixture
and the edge of the parking deck. Older garages may not have the 42" stall wall found in newer garages.
