INSTALLATION GUIDELINES:
Below grade luminaires often become ineffective or inoperable simply because they are not installed and maintained
correctly. While it is tempting to install these fixtures at or 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, below-grade luminaires can be installed in a
manner that will promote easy maintenance and longevity. The following installation methods represent our best
recommendations.
Isolate and Elevate:
The fundamentals of a clean, maintainable installation.
Create a Buffer Zone:
When the fixtures are to be installed in
areas planted in ground cover or 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 pruning.
• Rock fill provides drainage around fixture and helps keep the lens clean.
• Visually looks like a flush mounted installation.
Install in Concrete:
Another option for installation in 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 INSTALLATIONS IN CONCRETE:
• Allows higher wattage lamps because concrete
makes an excellent heat-sink.
• Helps prevent lens overgrowth.
•
Allows edging without scratching fixture.
• Provides drainage around fixture and helps keep the
lens clean.
• Visually looks like a flush mounted installation.
NOTE:
Always use adequate rebar surrounding the fixture
to prevent cracking of the concrete due to heat
expansion.

In Paved Areas:
Below-grade fixtures are not recommended
for walkover areas because high temperature lenses can burn
feet, hands, etc. However, they can be used in paved areas
that will not be used as a pathway or driveway. To make
fixture installation easier in paved areas, the optional Kim Grout
Mask may be used.
ADVANTAGES OF INSTALLATIONS IN PAVED AREAS:
•
Supports fixture during concrete pour.
•
Provides 2” grout space for finishing.
•
Can be easily tied into reinforcing rods used for paving
and fixture shell.
•
Easily adapts to any paving material.
