ABOUT THE SESSION

There are recent concerns that the use of LEDs and their higher blue wavelength content compared to the HPS lights they are replacing in outdoor applications will rapidly accelerate sky glow. A recent study documented increasing upward radiance from the Earth from 2012 to 2016 using satellite imagery, and proposed the “rebound effect” is to blame for lowering the cost of light, hence leading users to simply install more of it. This presentation will address the causes and economics of increased nighttime lighting use, and pose solutions for the future.

LEARNING OBJECTIVES
  • Understand the primary drivers responsible for increasing use of light at night around the world.
  • Learn where this growth is happening.
  • Learn the relative influences that different lighting characteristics have on light in the night sky.
  • Recognize how LEDs and controls offer capabilities for addressing light at night concerns better than any other outdoor lighting technology invented to date.
