Jan 01, 2016 · In this study, we investigated germicidal effects of UVC-LEDs at wavelengths of 266, 270, 275, and 279 nm, and a UV lamp at 254 nm was applied to the pathogens at an intensity similar to those of UV-LEDs. UV lamps emit a considerably high irradiation intensity of light in natural conditions, which leads to a high inactivation effect.
