    en.wikipedia.org/wiki/Stroboscopic_effect

    The temporal light modulation may come from fluctuations of the light source itself or may be due to the application of certain dimming or light level regulation technologies. Another cause of light modulations may be lamps with unfiltered pulse-width modulation type external dimmers. Whether this is so may be tested with any quickly-rotating ...

    Therefore, a significant reduction of heat output will occur with a relatively small reduction in voltage. An incandescent lamp will dim due to lower heat creation in the filament, as well as lower conversion of heat to light. Generally speaking, no damage will occur but functionality will be impaired.

  7. Light effects on circadian rhythm - Wikipedia

    In rats, constant light eventually disrupts the cycle to the point that memory and stress coping may be impaired. [15] The intensity and the wavelength of light influence entrainment. [2] Dim light can affect entrainment relative to darkness. [16] Brighter light is more effective than dim light. [12]
