Abstract
A transilluminator having two sets of tubes selectively providing light in the ultraviolet and visible ranges. The sets of tubes are arranged in two rows on opposite sides of a reflector in a housing having windows with lenses in opposite sides. The two sets of tubes have separate circuits sharing a common ON/OFF switch and a mercury switch mounted to the housing. With the device on, the orientation of the housing determines which of the two sets of tubes is on and which is off. Two sets of mounts to stably retain the housing on a planar surface are arranged on the opposite sides so that the housing may be positioned and used in two orientations. In either orientation, the upwardly facing lamps are energized while the downwardly facing lamps are turned off.
