Transitioning from Incandescent to Fluorescent: Insights from EISA 2007

DESCRIPTION

The Energy Independence and Security Act (EISA) of 2007 marked a significant shift in lighting standards, highlighting the inefficiencies of incandescent bulbs and promoting higher efficacy lighting options. This review explores the transition from traditional T12 to T8 and T5 fluorescent systems, emphasizing the importance of lumen maintenance and new DOE standards. With many outdated fixtures still in use, upgrading to efficient fluorescent options can lead to substantial energy savings, enhancing both efficiency and sustainability across North America.

  1. EISA 2007 More than Incandescent Bulbs

  2. Review: Incandescent Bulbs and theEnergy Independence and Security Act of 2007:

  3. 2014 2013 2012

  4. PIRL Halogen

  5. Source: ECOS

  6. Linear Fluorescent

  7. T8: Better in Many Ways

  8. EISA 2007:Incandescent and Fluorescent Timeline

  9. New DOE Fluorescent Standards

  10. Summary of Lamps Affected by 2012 DOE Standards New standards are based on EFFICACY – higher lumens per watt and higher CRI ratings • T12s • Majority of 4’ lamps fail • All U-Bents fail • 110W 8’ HO lamps fail • T8 • 700 Series Fail • T5 • All pass

  11. How many T12 & T8 Fluorescent sockets are there in North America?

  12. Linear Fluorescents in each Segment

  13. Switch from 34W T12 System to 32W T8 System

  14. Lumen Maintenance T5 T8 T12

  15. Key Points • T12s are everywhere • The further they are from a metro area • the less they’ll be sought out for upgrades • You can make the difference • And while you’re at it: • Every old-technology metal halide high-bay light in your service area could be replaced by T5 or T8 fluorescent fixtures and save 40-60% power • Upgrading one 400W metal halide fixture can do as much as upgrading 5 or 6 4-lamp T12 troffers
