Potential for 35-70% Energy Savings
Outdoor Lighting Program
• Lower energy costs
» 35-60% savings vs. high-pressure sodium vapor fixtures
» 70% savings vs. mercury vapor fixtures
» 10-20% additional savings with controls
• Lower maintenance costs
» Luminaire life expectancies significantly longer
» Integrated system controls help optimize maintenance delivery
• Reduced GHG emissions» For a city with 150,000 streetlights,
potential to avoid >40,000 tons of CO2e/year

Anchorage LED Retrofit Program: Phase I
Outdoor Lighting Program
• Phase I Key Figures• Phase I Retrofit» 4,200 150W and 250W HPS Fixtures
Resident Survey of New Fixtures
Outdoor Lighting Program
Residents overwhelmingly approved white light over existing high-pressure sodium system
• Two Resident Surveys: March and December 2008 » 130 male and female residents ages 17-71 » Tested 2 kinds of white light technology » Also tested dimming systems / centralized control

Obstacles Particular To Street Lighting Projects
Outdoor Lighting Program
• Concerns about efficacy of new technology
• Limited budget for large projects
• Standards do not fully capture benefits of new technology
17
Retrofit Roadmap
Define High-Level Project Goals
Conduct System Audit
Select replacementtechnologies
*Plan and deploy a small scale pilot test
Conduct detailed economic analysis
Craft business case for full-scale
implementation
Navigate local approvals process
Evaluate existing equipment and define opportunities for system improvement
Review projects that have tested and deployed these technologies
Include objective and subjective evaluations *Optional, if no other tests are
relevant.
Conduct assessment of local finance options available to your municipality or
utility
Analyze various proposals for financing and realizing a retrofit
Generate final requirements, purchasing specifications, and finalize finance plan
Commit to goals, timeline, and necessary staff resources
