Seattle LED Adaptive Lighting Study
The Northwest region operates approximately 1.7 million streetlights consuming an approximate average 150 MW. The City of Seattle has been actively converting its existing High Pressure Sodium (HPS) street lighting to light emitting diode (LED) lighting. The City reduced energy consumption by more than forty percent through this process (Smalley 2012). LED streetlights, coupled with…
