Abstract : A flashlight adaptation of an ultraviolet (UV) source has been made with a battery/converter supply powering a mercury vapor lamp. Two D-size common flashlight batteries power a single dc-ac modified Royer inverter whose output drives the UV lamp. The small circular UV fluorescent mercury-glow-discharge lamp is powered by a roughly 250-V square wave. It is eye safe. Illumination is confined to several square inches to preserve security in the presence of visible reradiation from the fluorescent map surface. The continuous operation capability exceeds 10 hr above roughly 50F. (Author)
