A mount for a light assembly in a luminaire has a base section and mounting arms upstanding from the base section. The image display device 30 includes an image forming device 40, and an optical system 50 that guides an image, which originates from the image forming device 40, into a pupil of a viewer. When enabled, the system controls the exit path of exhaust gas such that it is routed to the dump body during normal operating conditions. Each of the enclosures has a molded feature that can be used to verify surface finish quality and color consistency of the injection molded parts used to fabricate the enclosure. The order request, from a host or user, includes a list of the files on the tape from which to generate, based on the location information in the file location table, a reordered list defining an order for accessing the files on the tape. According to one aspect, the invention is a system including an LED for emitting UV-C radiation, a mount for directing emitted UV-C radiation toward the optically transparent element, and control circuitry for driving the LED.
