Fixed position hybrid germicidal irradiation apparatus, method, and system

A fixed position hybrid germicidal irradiation apparatus, method, and system for ultraviolet germicidal irradiation. A plurality of emitters may be coupled to a substantially rectangular housing configured to be coupled to a standard commercial lighting fitting. A second plurality of emitters may be coupled to the substantially rectangular housing. The first plurality of emitters and the second plurality of emitters are operable to emit UV-C radiation at a wavelength of about 265 nanometers and near-UV radiation at a wavelength of about 405 nanometers respectively. UV-C sensors are configured to measure the amount of UV-C light or near UV-C light from a target surface. A controller may be configured to engage with the UV-C sensors to determine the amount of UV-C radiation collected by the UV-C sensors. The improved apparatus, method, and system reduces exposure time by varying the intensity and wavelength of the UV administered, while concurrently reducing UV overexposure.
