Effect of organic light-emitting diode on nighttime task performance and melatonin secretion: Randomized controlled trials.
This study aimed to determine whether organic light-emitting diode (OLED) lighting with low intensity and color temperature (150 lux, 3000 K) maintains nighttime task performance and reduces melatonin suppression compared with a generally used LED lighting with high intensity and color temperature (750 lux, 5000 K).
