Radiometrically Equivalent Comparison of 254 nm Low-Pressure Mercury Lamps and InGaN 280 nm UV–C LEDs for Surface Disinfection

Abstract Ultraviolet germicidal irradiation (UVGI) is traditionally based on low-pressure mercury lamps emitting at 254 nm, whereas UV–C light-emitting diodes (LEDs) have emerged as promising mercury-free alternatives. However, direct comparisons between these technologies are fr...
