1. A method for treating a biological fluid comprising:
providing a biological fluid in admixture with a photoactive pathogen inactivation compound; and
illuminating the biological fluid with ultraviolet light with a first peak wavelength of from about 315 nm to about 350 nm emitted by a set of one or more first light sources, wherein each of the one or more first light sources emits light has a full-width half-maximum (FWHM) spectral bandwidth of less than 20 nanometers, and
wherein illuminating the biological fluid occurs for a duration and at an intensity sufficient to inactivate a pathogen in the biological fluid when present.
