Abstract: A U-shaped compact fluorescent sun-tanning lamp (10) capable of generating and transmitting desired and undesired wavelengths of ultraviolet radiation, for example, the desired wavelength is in the range of 352 nm and the undesired wavelength is in the range of 254 nm. The lamp (10) comprises two lamp tubes (12) that are transparent to the desired wavelength of the ultraviolet radiation and substantially opaque to the undesired wavelength of the ultraviolet radiation. The tubes (12) are connected at the upper portion by a bight (14) that in an unmodified state is transparent to both the desired and the undesired wavelengths of the ultraviolet radiation. A modification (16) on the bight (14) is opaque to at least the undesired wavelength of ultraviolet radiation. In a preferred embodiment the modification is a ceramic paint (18).
