Holiday Lights from Space
Average Rating: ( 0 votes)
Images from City Lab Satellite photos show an increase in evening light during the holidays. It appears that all those holiday lights we put up have a measurable effect on the nighttime sky, according to measurements taken from NASA's Suomi satellite. In the photos above and below, green represents an increase in average evening light output during the holidays. All told, American cities and suburbs can be as much as 50% brighter than normal between Thanksgiving and New Year's. That's a lot of holiday cheer. And it means a lot of extra electricity flows through the grid during the holidays. So how can we offset that with energy savings the rest of the year? Simple. Use outdoor LED security lights (preferrably ones with motion sensors) to keep your property secure at night: Hedley White 7 1/4-Inch High Security Light , Wynnsboro Black Aluminum LED Outdoor Up and Downlight And to offset light pollution, so our cities don't look like radioactive blobs when viewed from above? Try dark sky lighting around your property: Hatteras Bay Bronze 9-Inch Wide Kichler Outdoor Wall Light , Modern Atlantis Titanium 24-Inch High Hinkley Outdoor Light And while we're at it, now is a great time to replace your current Christmas lights with a colorful string of LEDs . We promise you won't miss the annual bulb replacing that accompanies those old incandescent strings.
