2015 U.S. Lighting Market Characterization

You are here

The latest version of the U.S. Lighting Market Characterization estimates the installed stock, energy use, and lumen production of all general-illumination lighting products operating in the U.S. in 2015.

Estimates were based on building-lighting audits, industry surveys, national lighting product shipment data, and interviews with lighting professionals and subject matter experts. Among the key findings:

  • U.S. lighting as a whole consumed 641 TWh of electricity, or approximately 17% of the country’s total electricity use.
  • Approximately 37% of the lighting electricity was consumed in the commercial sector. The outdoor sector was the second-largest lighting electricity consumer, at 32% of overall consumption, while the residential sector ranked third at 23%.
  • Overall, LED lighting penetration into all sectors has made significant strides since 2010, representing 8% of overall lighting inventory in 2015 vs. less than 1% in 2010.
  • The outdoor sector ranks highest in LED penetration, at 23% of that sector’s lighting inventory (up from 8% in 2010) – followed by the commercial (10%, up from 2%), residential (7%, up from less than 1%), and industrial (4%, up from less than 1%) sectors.
  • Across all sectors, the lighting stock has become more efficient, with the average system efficacy of installed lighting increasing from 36 lm/W in 2001, to 39 lmW in 2010, and now to 51 lm/W in 2015. Overall, average lighting efficacy in the U.S. has increased by more than 40% since 2001.
