The U.S. Department of Energy’s latest “Energy Savings Forecast of Solid-State Lighting in General Illumination Applications” report predicts that LED lighting sales will grow rapidly through the remainder of the decade and beyond. By 2035, 86% of installed lamps and luminaires across all categories will be LEDs, up from 6% in 2015. As a result, energy use for lighting in 2035 will be 75% lower than it would have been if LEDs had not entered the market, the report says. DOE estimates that LEDs will compose about 30% of U.S. lighting installations by 2020.

Most of the 5.1 quads of projected energy savings by 2035 will be attributable to two commercial lighting applications (linear and low/high-bay), one residential application (A-type), and one that crosses ­both residential and commercial (direc­tional). Connected lighting and other control technologies will account for almost 2.3 quads of the total savings. By 2035, “LED products will dominate every general lighting niche,” the report says.
