 The City of Chula Vista Public Works Department is conducting an energy efficient streetlight technology assessment. The goal of this comprehensive assessment is to seek out new streetlight technologies that reduce energy consumption and extend the maintenance period without reducing existing light levels.
This multi-phase project will compare the best new solid state (LED), high-pressure sodium (HPS) and induction technologies to existing HPS luminaires that are less energy efficient, maintenance intensive and less environmentally sensitive. The scope of this project is as follows:
Project Update
Based on the Streetlight Assessment Project's results, the City has selected LED technologies as the most preferred, energy efficient streetlight type. Compared to traditional fixtures, LED streetlights typically reduce energy use by 50%, last up to 100,000 hours (equivalent to 20+ years), and provide better light quality for public safety purposes. In July 2011, the City began to retrofit approximately 4,600 streetlights along residential roadways with the energy-saving LED technology. This project is being wholly funded through a low-interest California Energy Commission loan (subsidized by the American Recovery & Reinvestment Act) and San Diego Gas & Electric incentives. The resulting utility cost savings will be used to repay the 10-year loan. City staff is now working to secure state and federal funding to also convert streetlights along major (or arterial) roadways to LED technology.
Phase One
- Began in November of 2008
- Purpose was to establish minimum standards for LED and induction lights in order to find the best of the best products available. | View Draft Standards
Phase Two (or the beta test phase of the project)
- Purpose was to install "production quality" sample fixtures at key sites in the City of Chula Vista.
- Test fixtures are being evaluated based on the following criteria: Quality, reliability and aesthetics, serviceability, performance; based on photometric reports and field observations, energy consumption, cost (initial/return on investment) and manufacturer warranty.
- This phase is ongoing and could take up to 24 months to complete.
Phase Three (Final)
- Recommendation of a product or group of products that will replace or enhance existing HPS fixtures citywide.
Current Inventory
- 9,014 Streetlight Luminaires:
- 100 Watt HPS = 4,695 units
- 150 Watt HPS = 540 units
- 250 Watt HPS = 3,069 units energized (700 were shut off in 2009)
- Miscellaneous = 10 units (3-incandescent, 7-induction)

Secondary Beta Test Sites:
- North Second Avenue north of C Street (3-85 Watt Induction)
- Taber Drive south of De La Toba Road (3-50 Watt Induction)
Test Parameters:
- Test will be ongoing and will change as new technology becomes available.
- Evaluate quality/reliability and ease of installation.
- Evaluate performance based on photometric data and field observation.
- Energy cost savings analysis provided by SDG&E.
- Maintenance/Lifecycle costs and funding options will be analyzed by City of Chula Vista and it's consultant team.
