RE: Alternate Street Lighting - Denton

Public Works has no objection to the installation of General Electric
Deca-shield II Luminaires as an alternate to the Kim lights on these
projects. The first and foremost reason for this is the obvious
savings of 58%'over the Kim light~ ($11,340.00 vs. $3,220.00 per
installation). Secondly, the operations and maintenance cost for
the City will remain the same.
The only concern is the appearance of the pole, especially after
a period of time. However, TU Electric will be fully responsible
for this maintenance. The paint color should be similar to the
existing Klm lights.
As far as a general policy is concerned, I believe that this should
be tried but policy should be made after practical evaluation which
staff believes will come about with the installation of the
Deca-shield II Luminares at the referenced locations. Staff is
under the impression that this type of light does meet the Subdivision
requirement under Appendix A, VI-A: "Street lighting shall conform
to the latest edition of the Illuminating Engineering Society
Handbook."
If we can be of further assistance regarding this matter, please
contact either mYself or Per Birdsall at 462-8495.

Dear Mr. Goram:
Enclosed is information you requested pertaining to the Genera]
Electric Decashield II luminaire. TU Electric is offering this
as an alternative roadway light for commercial areas and major
thoroughfares. The photometric applications data on this style
of light is very similar to that of the Rim street light. (See
attached photometric data.) As this data indicates, these lights
can be used on major thoroughfares without any difference in the
footcandle lighting or uniformity ratio when compared with the
Kim street light.
Whereas the Kim lights are anodized aluminum, requiring no
painting, the General Electric light standard requires pain[i~f.
There are no other noticeable differences between the Klm light
and the General Electric light.
The General Electric light can be installed for an approximate
charge of $1,340.00 for each 30 foot, double fixture street
light. The cost for the double fixture Rim light installed in a
similar manner is $3,220.00. Credits can be applied to these
prices for customer installed foundations and conduit.
If you have any questions concerning this matter, please call Tim
Brancheau at 323-8910.
Sincerely,
Thomas G. Parsons
District Manager

DECASHIELD' II luminaires from the
General Electric Lighting Systems Department
combine a contemporary rectilinear shape
with an efficient optical system to provide
attractive and effective lighting for roadways,
parking areas, malls, walkways, industrial
parks, residential complexes and other areas
where aesthetics and energy efficient lighting
are needed for safety, security, and nighttime
attraction.
Curve: 35177316 M-C-IV Curve; 35-177312 S-C II
Mounted one, two, or four to a square
pole, these dark bronze luminaires fit into
many architectural schemes with both a com-
plementary daytime appearance and afterdark
illumination. Decashield II Luminaires come
in two sizes, the DS-250 and DS-400, for
mounting at heights shown below. Simply
determine the light level (footcandles) you
need for your area and consult the light
distribution curves and conversion charts to
determine the best mounting heights, watt-
ages, and pole spacing.

GENERAL DESCRIPTION -- The new contemporary-shaped DECASHIELD II Lumif~aire is designed for the energy-e c ant I ghting of stre~ts,
parking areas, waikways, mails and other outdoor areas where brightness control and compahbi~ity with architectural surroundings are desired
TWO WATTAGE SIZES -- The DECASHIELD II Luminaire comes in two sizes:
· DS-250 for 70, 100, 150, 200, and 250 watt high pressure sodium or 175 and 250 watt metal halide/mercury light sources.
* DS-400 for 200, 250, and 400 watt high pressure sodium or 400 watt metal halide/mercury light sources.
CONSTRUCTION -- Heavy gauge,
formed aluminum housing with attrac-
tive dark bronze paint finish (also ·
available in seven other colors).,
aluminum arm,
rods combine with
mounting to sq
An upward 2.5 degree tilt on the arm
compensates for the optical illusionF i: :
