Black-light blue fluorescent lamp assemblies (26), in accordance with the present invention, comprise a black-light fluorescent lamp (10) with a glass tube (12) as well as two terminal caps (14) and a tube (16) of a semi-rigid, spectrally selective polymeric material that is coextensive with the glass tube (12) of the lamp (10) and is securely fastened to the terminal caps (14) of the fluorescent lamp (10) are disclosed as well as methods for their manufacture. The lamp may be any commercially available BL fluorescent lamp and thus includes an elongated glass tube (12) and a metal terminal cap (14) at each end of the glass tube, each cap having a flange portion (14a) adjacent the glass tube (12). The polymeric material of the tube (16) that covers the BL fluorescent lamp is formulated, such as by incorporating selected resins, to spectrally select light from the BL lamp in the spectral range of wavelengths of from about 300 nm (namometers) to about 400 nm and to filter out light of wavelengths greater than about 400 nm. |
