Efficient lighting programs are in flux thanks to new technologies and evolving minimum lighting efficiency standards resulting in shifting baselines. The US Energy Independence and Security Act of 2007 phaseout of general-service incandescent lamps is underway, and new lighting options are emerging, including efficient halogens and light-emitting diodes (LEDs). Many utilities have voiced plans to shift incentives from basic spiral compact fluorescent lamps (CFLs) to specialty CFLs. Additionally, an increasing number of utilities and statewide efficiency organizations are providing incentives for LED bulbs at retail stores or plan to provide them in the next year. But there are still numerous opportunities for standard CFLs to provide program savings given consistently low socket saturation. However this shakes out, it’s clear that residential lighting programs as we know them can no longer provide the majority of demand-side management portfolio savings upon which utilities have relied.
