Energy Efficiency in Traffic Signal Lighting -- Near Infrared Camera Surveys
Channel: Climate Science Demonstrations
Date: 03/02/2020

What do you see?  With short-wavelength infrared cameras, you can survey the traffic signals at several representative intersections.  Can you tell which lamps in the video are LED's and which are using incandescent bulbs?

A little observation of stop lights provides valuable experience in using near infrared cameras. These cameras are a powerful tool when making surveys of the energy efficiency of many types of lighting.
