New study shows some LED lights can harm wildlife

Researchers have concluded that certain types of LED lights can be harmful toward a wide variety of wildlife, calling attention to the potential hazards of the rapid expansion of LED light usage. Though LEDs made up only 9 percent of the global market in 2011, that number is expected to rise to 69 percent by 2020. In a study published in the Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, researchers concluded that blue and white LED lighting is the most harmful to wildlife, particularly animals such as sea turtles and insects, while green, amber and yellow are more favorable.
