Abstract: The present disclosure relates to ultraviolet (UV) disinfection devices, systems and methods for automatically preheating a plurality of UV emitters of the UV disinfection device in response to the UV disinfection device being coupled to a power source, independent of the activation of the plurality of EV emitters, or a ballast or power supply thereof, in order to minimize a total disinfection cycle time. In certain optional embodiments, the present disclosure relates to UV disinfection devices, systems and methods for dynamically adjusting a power-level of each of the plurality of UV emitters based on corresponding UV sensor measurements in order to further minimize the total disinfection cycle time. In other optional embodiments, the present disclosure relates to UV disinfection devices, systems and methods for optimizing alignment of each of a plurality of UV emitters within a room in order to further minimize the total disinfection cycle time.
