LED bulb efficiency expected to continue improving as cost declines

Technology improvements for general service lighting, driven by federal efficiency standards, are leading to increased reliability and bulb life. As efficiency increases, residential electricity consumption for lighting declines over time. Although the initial purchase price is higher for more efficient technologies than for traditional bulbs, significant savings are achieved over the life of the bulb (also called a lamp).
