Re: Weberg
Exterior Lighting
We are proposing to use a 25' steel pole painted to match the light fixture
which will be mounted on a concrete base in the parking lot area. The light
fixture that will attach to the light pole will be a Guardco or equal and
will probably have a bronze finish and the lense will be of a controlled
pattern nature which will not illuminate off the Weberg site. I have
attached a cut sheet of that particular fixture.
The wall mounted fixtures will be utilized at the west elevation in the
trucking area and will also be a Guardco or equal light fixture, bronze in
pattern, with a controlled pattern light display.

Destned to stand the
test of tire.
The Ilea^ ,as and s' ,arp detailing
of the lumi: aire echo the timeless
design of the Gardco Form Ten
luminaire. Arm, yoke and wall units
are a!! finely balanced and in pro-
portion to mounting hardware.
Luminaires can be mounted to a
variety of poles, including the
exclusive Cruciform pole, crafted
from extruded aluminum with
Class 1, Architectural Anodic
coatings.
Ruggedly constructed
to make a lasting
contribution.
Aluminum housings are .first
etched and painted with an epoxy
undercoat ... then finished with a
thermosetting bronze polyester
for added durability. Tempered
glass doors are framed with
natural anodized aluminum and
sealed with extruded silicone
rubber.
Inside the luminaire, all miters and
joints are carefully sealed to ex-
clude weather, insects and dirt in-
defintely. The result is exceptional
durability with minimal
maintenance.
Ease of service is a design imper-
ative. Lens door frames swing
easiliy away"with spring -loaded,
stainless steel latch pins — re-
lamping is fast and requires no
tools.
With Danlux, planners can meet
specifications which demand
economy in price, without un-
duly compromising quality or
performance.
