Seattle City Light recently completed phase two of a four-year streetlight re-lamping project.
The work, which was completed about a month ahead of schedule, involved replacing 21,000 lamps. Added to last year’s work, City Light has now replaced the lamps on all its streetlights south of Denny Way.
In 2010, the utility is scheduled to replace lamps on streetlights from Denny Way north to N 65th Street. The final phase, from N. 65th to our northern suburbs, begins in 2011.
Planned re-lamping is designed to replace lamps shortly before the end of their expected lifecycle, avoiding burnouts and lowering maintenance costs. As crews replace the old lamps, they also are able to identify streetlights that have additional problems that need repair.
Once the crews finish the fourth section of City Light’s service territory, it will be time to start over in the first section as the lamps have an expected life of four to five years.
