The lamp is a strong ultraviolet radiator particularly having the radiation in the UV range of between about 310 and 350 nm substantially enhanced. The lamps are useful in industry particularly as a UV source in the graphic arts field, and for a strong source of ultraviolet radiation for humans, particularly radiation in the aforenoted range of wavelengths.
