title: Irradiance of visible light-curing units and voltage variation effects.
abstract: The irradiance in the wavelength of 450 to 500 nm of nine visible light-curing units was measured at 120 V input voltage. The highest irradiance was more than 20 times that of the lowest. Irradiance was also measured at 90 to 130 V input. Irradiance and depth of cure at lower input voltages were also examined.
