1. An upper room air germicidal light fixture comprising:
a light source configured to emit light, wherein the light is emitted at wavelengths capable of inactivating at least one species of pathogen disposed in air;
at least one lower baffle assembly disposed adjacent to the light source wherein said at least one lower baffle assembly enables air to flow through said at least one lower baffle assembly, wherein said at least one lower baffle is also configured to direct the light and to block or substantially dissipate incident light rays from the light source;
at least one upper baffle assembly disposed adjacent to the light source wherein said at least one upper baffle assembly enables air to flow through said at least one upper baffle assembly, wherein said at least one upper baffle is also configured to direct the light and to block or substantially dissipate incident light rays from the light source; and
at least one aperture defined by an opening between a corresponding set of upper and lower baffle assemblies, wherein the light emitted by the light source exits the fixture through said at least one aperture simultaneously in multiple directions,
wherein, when the germicidal light fixture is disposed in a room, surrounding room air will contact light exiting the apertures of said fixture, and room air traveling through said fixture will contact light inside and between the corresponding set of upper and lower baffle assemblies,
and wherein the at least one upper baffle assembly is adjustable, such that a size of the at least one aperture is adjustable based on an angular orientation of the at least one upper baffle assembly relative to the lower baffle assembly.

9. A germicidal light fixture comprising:
an upper room air germicidal light fixture configured to irradiate air with light in an upper portion of a room wherein:
the light is emitted at wavelengths capable of inactivating at least one species of pathogen disposed in air;
the upper room air germicidal UV light fixture comprises at least one baffle assembly configured to direct the light out of the fixture simultaneously in multiple directions;
the light from the fixture is substantially directed to portions of the room air that is are substantially adjacent to or above said fixture; and the upper room air germicidal UV light fixture comprises at least one fan, wherein the at least one fan is configured to increase the volume of room air that contacts the light emitted by the upper room air germicidal UV light fixture,
wherein the at least one baffle assembly is adjustable such that a size of at least one aperture defined by the at least one baffle assembly is adjustable based on an angular orientation of the at least one baffle assembly; and
wherein the at least one baffle assembly comprises at least one upper baffle assembly and at least one lower baffle assembly, wherein a single aperture is defined by a space between one upper baffle assembly and one lower baffle assembly.
