AGENDA TITLE: Approve Specifications and Authorize Advertisement for Bids for
216 metal halide lamps for Cherokee Lane streetlighting (EUD)
MEETING DATE: July 18, 2001
PREPARED BY: Electric Utility Director
RECOMMENDED ACTION: That the City Council approve the attached specifications and
authorize the advertisement for bids for 216 175 -watt metal halide
pulse -arc lamps manufactured by Philips Lighting, for installation in
streetlight fixtures on Cherokee Lane.
BACKGROUND INFORMATION: On February 26, 2001, Ron Peterson, Product Service Engineer for
Advance Transformer, met with Electric Utility Department staff to
help determine the cause of streetlight failures along Cherokee
Lane.
According to Mr. Peterson, there may be a mismatch between ballasts and the pulse -arc lamps installed
in the Cherokee Lane fixtures. However, Advance Transformer's manufacturing tolerances would place
about 60% of the ballasts within the operating tolerances of the Philips pulse -arc lamp, suggesting that
only about 40% of the ballasts may actually require replacement if operated with Philips bulbs. Toward
that end, Advance Transformers has furnished the department with 100 pulse -arc ballasts, and has
recommended that the City replace non -Philips lamps with Philips Lighting 175 -watt pulse -arc metal
halide lamps in an effort to achieve the department's desired level of performance for streetlights along
Cherokee Lane.
