DOE Finds LED Outdoor Lighting Color Temperatures are Warming Up

The U.S. Department of Energy’s CALiPER program has released a Snapshot Report on LED outdoor area lighting. Based on LED Lighting Facts® data through the second quarter of 2014, the report focuses on outdoor area/roadway luminaires, parking garage luminaires, canopy luminaires, and outdoor directional luminaires. As of July 1, 2014, area/roadway products alone comprised 23 percent of the LED Lighting Facts database, with the other three product categories comprising approximately 7 percent.

Among the report’s highlights:

  • The number of products listed by LED Lighting Facts continues to grow rapidly. An increasing percentage of those products are luminaires, and more and more of those luminaires are outdoor area lighting products.
  • The efficacy of outdoor area lighting products continues to rise, with mean performance now around 80–90 lm/W and the most efficacious products around 120–150 lm/W.
  • Likewise, lumen output has continued to increase. For example, there are now several listed products with lumen output comparable to a 400W high-pressure sodium streetlight. This is a notable change since the last Snapshot Report on this product category, which was published one year ago.
  • Early LED outdoor area lighting products were often known for their higher CCTs (e.g., 6500 K). Today, 4000 K and 5000 K are the most common CCTs, and the mean CCT has shown a continual downward trend.
