Claim 0:
1. A handheld light assembly for irradiating pathogens on a surface, comprising:
a housing;
a lamp disposed in said housing for irradiating surfaces with disinfecting ultraviolet light having a single peak wavelength of about 222 nm thereby generating an irradiation zone on the surface;
a processor programmed with a predetermined distance between the surface and said lamp for optimal transmission of irradiance to said surface from said lamp;
a distance measuring device being offset from said lamp and including a transmitter for transmitting an invisible distances signal from said offset position toward the surface being irradiated and a sensor for receiving the transmitted signal reflected from the surface;
said transmitter being oriented to transmit the distance signal from the offset position to a central portion of the irradiation zone on the surface being irradiated for identifying distance between said lamp and said surface being irradiated; and
said processor programmed to calculate distance between said lamp and the central portion of the irradiation zone at the surface being irradiated from said signal transmitted from said offset position for providing user feedback that said lamp is disposed at the predetermined distance from surface at the central portion of the irradiation zone.
