Installation Instructions
In-grade luminaires often become ineffective or inoperable simply
because they are not installed and maintained correctly. While it is
tempting to install these fixtures below grade, this generally turns out
to be unsatisfactory unless the installation is in a paved area. When
the fixtures are installed too low, they become a collection point for
dirt, mud and encroaching ground cover. With a little preplanning
and care, in-grade luminaires can be installed in a manner that will
promote easy maintenance and longevity. The following installation
methods represent our best recommendations.
When the fixtures are to be installed in areas planted in ground
cover and shrubbery, a buffer zone is needed to prevent lens
overgrowth as the plants mature. Elevating the fixture will
encourage water runoff around the unit rather than over the top.
Advantages of a buffer zone:
•
Helps prevent lens overgrowth.
•
Provides a defined edge for trimming.
•
Provides drainage around fixture and helps keep the lens clean.
•
Rock-fill partially buffers fixture from corrosive soil and improves
ground drainage.
•
Visually looks like a flush mounted installation.

INSTALLATION GUIDELINES:
Remember,
always
isolate and elevate
.
Another option for ground cover, shrubbery or lawn areas is
to encase the fixture in concrete. This has some additional advantages
over the rock-fill method (above).
Advantages of concrete installation:
•
Allows higher wattage lamps because concrete makes
an excellent heat sink.
•
Totally isolates fixture from corrosive soils.
•
Helps prevent lens overgrowth.
•
Allows edging without scratching fixture.
•
Provides drainage around fixture and helps keep
the lens clean.
•
Rock-fill partially buffers fixture from corrosive soil and improves
ground drainage.
•
Visually looks like a flush mounted installation.
Note:
Always use adequate rebar surrounding the fixture to prevent cracking of concrete.
To make fixture installation easier in concrete, use Rebar Cage
Anchor (RCA81/82/83) and tie into paving rebar to support fixture
during concrete pour.
Advantages of paved area installation with
rebar cage anchor
•
Supports fixture during concrete pour.
•
Can be easily tied into reinforcing rods used for paving
•
Easily adapts to any paving material.
NOTE:
Concrete foundation is to be designed according
to local soil conditions (by others).
