and meet the following requirements:
1] completely assembled (including a 2" slipfitter);
2] one piece aluminum housing with grey polyester/polyuerthane resin based powder coat finish;
3] low pressure sodium vapor (LPSV) furnished with a polycarbonate lens;
4] formed segmented specular anodized aluminum and prepainted white aluminum reflector;
4] integral 120 V high reactance HPF lamp ballast mounted on door at rear secured with removable hinges;
5] enclosed porcelain socket lampholder with nickel-plated brass contact to hold a single-end bayonet base LPS;
lamp at one end; and
6] built-in 120 V Type IV photoelectric control unit.
The luminaires shall also meet the following optical requirements:
Certified luminaire performance data shall be furnished with "Equipment List and Drawings,"
conforming to the Caltrans Standard Specifications. This data shall include complete photometric test
data in the form of isolux charts at a scale of one-inch equals twenty feet (1" = 20') for the luminaire and
lamp sizes indicated on the plans. Alternate data may be in the form of horizontal footcandle values
recorded on a fifteen foot x fifteen foot (15' X 15') grid, extending one hundred fifty feet (150')
longitudinally from the light source and fifteen feet (15') behind and one hundred twenty feet (120') in
front of the light source for the luminaire and lamp size s indicated on the plan. The horizontal
footcandle levels in the data submitted shall provide a minimum horizontal footcandle level of at least
0.9 fc average maintained in the intersection with a minimum of 0.60 at centerline and 0.15 at the
furthest crosswalk. Failure to satisfactorily meet the reverenced values will be justifications for refusal
of bid at the sole option of the AGENCY.
The test shall be performed by an independent and recognized testing laboratory or by the
manufacturer's laboratory. When the tests are performed by the manufacturer's laboratory, the test
data shall be certified. Subsequent to CONTRACTOR's installation of any street light luminaires, field
checks may be performed at random by the Public Works Director or his assigned representative and
calculated according to the "I.E.S. Guide for Photometric Measurement of Roadway Lighting
Installations (LM-50)," approved in July 1974. Failure to satisfactorily meet or exceed the referenced
values during field check will be justification for replacement by the CONTRACTOR at the sole option
of the AGENCY.
8.
LOW PRESSURE SODIUM VAPOR LAMPS
Low pressure sodium vapor lamps shall:
1] be single ended;
2] be bayonet base;
3] be tubular gas discharge lamps suitable for use in street light applications.
4] be able to reach eighty percent (80%) of light output with nine (9) minutes and to restrike within one (1)
minute after an outage due to power interruption or voltage drop at the lamp socket;
5] have a base with sufficient space to allow the installer to indicate the month and year of lamp installation.*

have one hundred percent (100%) lumen maintenance during rated life and meet the following minimum
performance requirements:

If the AGENCY is required to replace any lamps during the first year after installation, the CONTRACTOR
agrees to reimburse the AGENCY for labor performed at the rate of $30.00 for each lamp failure and also to
furnish a replacement lamp to the AGENCY at no cost.
ANCHOR BOLTS FOR ANCHOR BASE POLES
Anchor Bolts shall be of the type and size as shown on San Diego Area Regional Standard Drawing E1. Anchor bolts shall conform to the specifications of ASTM A 307, and shall be provided with two nuts
and two washers each. Bolts, nuts, and washers shall be galvanized by the hot-dip process
conforming to ASTM A 153, or cadmium plated with Type NS coating conforming to ASTM A 165.
Plumbing of the standard shall be accomplished by adjusting the nuts on the anchor bolts before the
foundation cap is placed. Shims or other similar devices for plumbing or raking will not be permitted.
After plumbing the standard, anchor bolts shall be cut off 1/4 inch thick above the nuts and the
exposed surfaces shall be repaired.
See the attached “Direct Burial” & “Anchor Base” installation drawing for additional information.
10.
HOOK-UP TO SDG&E'S SERVICE POINT
Contact SDG&E for a service point. SDG&E will identify what service is available and where it is
located. Sometimes a new street light can be connected to an existing light system, but that very
seldom happens.
The service point should be in the City's right-of-way, otherwise the City will require an easement to the
service point (a SDG&E easement is not sufficient). Easements are expensive and time-consuming to
the developer. Avoid service runs across private property if at all possible!
11.
AS-BUILTS
Two (2) sets of "As-Built" drawings (see attached) must be given to the Public Works Inspector before
SDG&E will energize a light.
