Long‐Term Energy Goals • CEC goals up to 2018 – Achieve 50% reduction in res and 25% in nonres compared to 2007 levels (AB1109) – Manage the transition to 45lm/W minimum efficacy (Title 20)
• CEC goals beyond 2018 – Advise the legislature on further lighting goals (AB1109) – Net‐zero energy use in res (2020) and nonres (2030) – Achieve Global Warming Solutions Act (AB32) goals

Background • CFL sales and market saturation appear to have leveled off at around 30% of medium screw‐based sockets. • Evaluation efforts have focused mostly on purchasing decisions, not on long‐term consumer satisfaction. • Research and expert opinion suggest that the color quality and lamp life of CFLs are major shortcomings. • LEDs have inherent advantages: startup and dimming. • Despite ENERGY STAR standards for CFLs from 2000 onward, market saturation, even for omnidirectional, is 0, and allows any CCT within 7 steps of the Planckian Locus. • Little or no available research on what is the “right” CRI or binning for residential lamps – But incandescents are 100 CRI, zero steps from locus…
• LRC study found that observers could distinguish color differences of 2‐4 steps in real environments • CA Quality Specification requires 90 CRI, R9>0, all lamps within 4 steps of the locus • Consumer color quality research is being conducted by CLTC and CLASP funded by PG&E; results expected Summer 2013.

Energy Star Plus: Lamp Life • CA Quality Specification requires – 5‐year free replacement warranty – Rated life requirements from ENERGY STAR (25,000 min, 35,000 for “commercial”)
• LED replacement lamps are a new technology; their life in situ is not well understood • Research is necessary to find out typical failure mechanisms and how to avoid them

Future Development of the Spec Need quantitative tests for flicker and noise Need more research on color quality Will probably remain invisible to consumers Will need to be updated periodically in response to ENERGY STAR and market conditions • Will seek to influence ENERGY STAR revisions • Upcoming Title 20 and Title 24 rulemakings may make some elements of the Spec mandatory • • • •
