To permit visual observation of tanning effects obtained by a UV radiation lamp, the UV radiation emitting material has admixed thereto a coating material which provides auxiliary visible radiation output in the yellow-green spectral range of between about 490-600 nm. Suitable materials are: 13% of strontium aluminate, activated with cerium; 79% of barium disilicate, activated with lead; 3% of zinc silicate, activated with manganese; and 5% of calcium halogen phosphate, activated with antimony and manganese, with the spectral ranges shown in FIG. 1, or 12% of strontium aluminate, activated with cerium; 68% of barium disilicate, activated with lead; and 20% of calcium halogen phosphate, activated with antimony and manganese, with the spectral ranges shown in FIG. 2. |
