Worm lifespan is inversely proportional to wavelength energy. a Irradiance spectrum of the sun under direct or indirect sunlight, compared to the spectrum of white fluorescent tubes used in incubators and the laboratory (ambient room). b Detailed irradiance spectrum of white fluorescent tubes used in the laboratory (ambient room). c Total irradiance of UV light emitted by fluorescent white light versus solar radiation. d Lifespan under dark conditions of progeny derived from adult worms exposed to different photoperiods. e Lifespan of worms exposed permanently to blue, (f) green, (g) yellow, or (h) red LED light compared to controls kept in NL condition. Insets represent the spectrum of each color-specific LED
