DOE Report Finds Industrial Lighting Bright

April 13, 2017
The report shows substantial advances in efficacy and performance of luminaires listed for industrial applications in the database over the past three years.

The U.S. Department of Energy (DOE) delivered one of its CALiPER Snapshot reports covering the industrial lighting products in its LED Lighting Facts database, its first update on the industrial lighting category since June 2014. The report shows substantial advances in efficacy and performance of luminaires listed for industrial applications in the database over the past three years.

In June 2014, the mean efficacy for listed industrial luminaires was 93 lm/W; today, it’s about 20% higher, at 115 lm/W, DOE said in the report. Approximately 23% of the listed industrial products report a luminous efficacy greater than 130 lm/W, 5% exceed 150 lm/W and 1% exceed 175 lm/W. “These values are substantially higher than the average efficacy of metal -halide and fluorescent fixtures, which typically fall between 70 and 90 lm/W,” said the report’s summary.

DOE’s CALiPER (Commercially Available LED Product Evaluation and Reporting) Snapshot reports analyze the dataset—or subsets—from DOE’s LED Lighting Facts product list. They are designed to help industry stakeholders understand the current state and trajectory of the solid-state lighting market.
