  1. PEARLProgram for the Evaluation and Analysis of Residential Lighting May 4, 2006 Lighting Research CenterRensselaer Polytechnic Institute

  2. Table of Contents • Why PEARL? • Who is PEARL? • What has PEARL done? • What’s on the market? • PEARL measurements • PEARL results • Conclusions

  3. Why PEARL? • Watch-dog program for ENERGY STAR lighting products • CFLs • Fixtures • Concerns over product quality • Premature failure • Not bright enough • Gets much dimmer over time • Slow to reach full light output • No industry-wide QA mechanism or challenge program exists

  4. Who is PEARL? • Bonneville Power Administration • Midwest Energy Efficiency Alliance • Natural Resources Canada • Natural Resources Defense Council – Noah Horowitz • New York Start Energy Research and Development Authority • Northeast Energy Efficiency Partnerships • Northwest Energy Efficiency Alliance • Pacific Gas & Electric • Sacramento Municipal Utility District • San Diego Gas & Electric • Southern California Edison • Wisconsin Energy Conservation Corporation • US Environmental Protection Agency • US Department of Energy

  5. What has PEARL done? • Program started 2000 • Completed six cycles (sets) of testing • Tested • 123 CFL models from 22 manufacturers • 53 Fixture models from 19 manufacturers • Currently receiving products for Cycle 7 • Testing • 30 CFL models from 15 manufacturers

  6. What’s on the Market? • Product selection • Based on what is available; • Retail • Electrical distributors • Lighting show rooms • Some internet • Shopping list is then cross referenced with ENERGY STAR website • Products are then purchased from sponsor locations

  7. What’s on the Market? CFL Types Bare Covered Reflector 2,167 CFLs from 114 manufacturers on ENERGY STAR website* *As of April 2006 Fixture Types Ceiling-mounted Wall-mounted Recessed Portable Outdoor 6,230 fixtures from 49 manufacturers on ENERGY STARwebsite*

  8. PEARL Measurements CFLs Initial measurements Efficacy Color properties Start and run-up time 1000-hr measurement Lumen maintenance Failures 40% of Rated Life measurements Lumen maintenance Failures Rapid Cycle Stress Test Fixtures Initial measurements Lamp/ballast efficacy Color properties Start time Ballast case temperature

  9. PEARL Results * In progress

  10. PEARL Results Percentage of Compliance with ENERGY STAR Spec for All CFLs tested in PEARL 100% 90% 80% 70% Cycle1 Cycle2 60% Cycle3 % of CFLs that Passed Cycle4 50% Cycle5 40% Cycle6 30% 20% 10% 0% Efficacy (lm/W) 1000-hour 40%-life Rapid Cycle Stress Lumen Lumen Test Maintenance Maintenance Parameters

  11. PEARL Results

  12. PEARL Results

  13. PEARL • ENERGY STAR is currently working with its partners to develop a self-sustaining watch-dog program that will be funded by the manufacturers • US Environmental Protection Agency is working with the fixture manufacturers • US Department of Energy is working with the CFL manufacturers • It is expected that these programs will be in place when PEARL Cycle 7 is complete

  14. Conclusions • Products have been improving over time • PEARL has continually expanded its coverage of products and amount of testing • Only been able to touch a very small percentage of the products on the market • 5.6% for CFLs & 0.8% for fixtures • Not easy to find some products • Watchdog program plays an important role
