LED lights are extra environment friendly than fluorescent lights, but in addition they produce a fair quantity of light within the blue spectrum. Richard Hansler, a light-weight researcher at John Carroll University in Cleveland, notes that strange incandescent lights additionally produce some blue light, though less than most fluorescent lightbulbs. While light of any type can suppress the secretion of melatonin, blue gentle at night time does so more powerfully. Harvard researchers and their colleagues conducted an experiment comparing the results of 6.5 hours of exposure to blue gentle to publicity to green gentle of comparable brightness.
