2019 Reduced Wattage Lamp Replacement Program Long-Term Monitoring and Tracking Report

The Northwest Energy Efficiency Alliance’s (NEEA) Reduced Wattage Lamp Replacement (RWLR) Market Transformation program began in 2014 and transitioned to Long-Term Monitoring and Tracking (LTMT) in late 2018. The program sought to shift lighting distributors’ sales of replacement lamps from 32-watt linear fluorescent lamps (LFLs) to reduced wattage LFLs (25 and 28-watt).

This report, prepared by Evergreen Economics, presents the 2019 LTMT results. The overall finding is that the RWLR program market effects persisted in 2019 following NEEA’s exit from the market. Between 2018 and 2019:

  • Distributors’ sales share of reduced wattage LFLs within the LFL market remained steady, even as the LFL market continued to give way to TLEDs. Former participants’ reduced wattage LFL share of their LFL sales increased slightly from 48% to 49%, and nonparticipants’ share held steady at 10%.
  • Participants’ stocking of reduced wattage LFLs fell slightly but only to make room for TLEDs, not because of a shift back to 32-watt LFLs.
  • The price of reduce wattage LFLs decreased, further reducing the incremental price between reduced wattage and 32-watt LFLs.
