ATTACHMENT B - PERFORMANCE REQUIREMENTS FOR THE PROPOSED
SOLAR POWERED STREET LIGHT SYSTEM
The City of Rosemead will install solar powered street lights on Walnut Grove Avenue, from
north of Guess Street, near the Rubio Wash, in the north, to north of Marshall Street in the south,
a distance of about 1,480 ft. This segment is classified as a Collector Road with low pedestrian
conflicts. The electric utilities were recently undergrounded in this section and the SCE poles
were removed. Since then, no new lighting has been installed.
This project involves installation of solar powered lighting which will eliminate the need for
electrical power sources and service cabinets, as well as a lot of the associated new conduits. The
City also desires to keep the footprint of the equipment small within reason, but ensure that the
product will perform as intended and meet all operational parameters as referenced on this
document. The product also must meet all standard lighting requirements and back it up with a
replacement and repair warranty. To ensure this, the manufacturer must provide proof of
experience and performance history. Since this technology is fairly new, it is also understood that
there are no standardization in the market yet, and there are a variety of products available which
would be difficult to compare directly.
Based on these requirements, the following parameters are being incorporated to the bid, which
are primarily performance based. All bidders are required to furnish to the City the proposed
brand name/manufacturer name for the proposed materials, products, and/or equipment meeting
the performance requirements on this document, as part of their bid, to be considered responsive.
In conformance with General Provisions, Section 4-1.6, all bidders shall furnish data including
complete calculations, technical specifications, and/or published documents and any and all
information as required on this document as part of their bid submittals, and all cost of furnishing
this information shall be included in the bid, no additional compensation will be allowed.

equivalent software showing how the lighting fixtures will meet all lighting standard, IES
RP-8-21 “Recommended Practice for Lighting Roadway and Parking Facilities” (dated

indicate clearly what values are being attained for luminance, uniformity ratios,
lumens/watt, and total lumen output per fixture. These shall match all test data provided
for the lighting system and fixtures. Poles shall be placed in a uniform staggered pattern
at regular intervals to the extent possible to maintain aesthetics of the street. Pole spacing
requirements shall be as follows: 130’ minimum distance and 170’ maximum distance
for staggered pattern.
