If I as a university professor approached my institutional review board and said I want to experiment on entire populations by introducing wavelengths of light most associated with harmful biological and ecological effects, they would laugh me out the door, down the street and out of my office,” Longcore says. “Fortunately, we can now use much warmer-colored LEDs that eliminate the blue spike in spectrum that is so damaging because it scatters so much in Earth’s atmosphere.
