Where can I get "black light" (longwave ultraviolet) fluorescent-lamp tubes?? When disco music was big in the '70s, they were available in every grocery store but now even the Edmund Scientific "Industrial" catalog doesn't have them except in super-expensive assemblies. I'm looking for a 4-watt UV tube to replace the white tube in a Radio Sh** battery-powered fluorescent lamp, to be used to illuminate fluorescent cave formations. (Actively growing white-calcite stalactites and stalagmites are usually fluorescent. They are blue under longwave UV, green when excited by a xenon strobe light. The fluorescence/phosphorescence is believed to be caused by included organic-decay products.) -- Frank Reid W9MKV @ WA8YVR NSS 9086 reid@gold.bacs.indiana.edu PO Box 5283 Bloomington IN 47407
