Abstract
A hand-held germicidal UV lamp includes housing for a UV light source and an aperture for allowing the transmission of UV light. A safety switch is provided on the housing which can be moved by an activation tool. A cover is provided over the switch having an opening for accessing the switch. The opening is sized so that a human finger cannot pass through the opening and move the switch. A light shield may be provided which surrounds the aperture and limits transmission of UV light.
