[QUOTE="user 4386, post: 507913, member: 4386"] I would question that, but you can certainly have fun with one. Safer to stick with long wavelength uv anyway (if you ever get short wavelength, also get uv goggles or you will burn your eyes) [b]Lamps for Viewing Fluorescent Minerals [/b] The lamps used to locate and study fluorescent minerals are very different from the ultraviolet lamps (called "black lights") sold in novelty stores. The novelty store lamps are not suitable for mineral studies for two reasons: 1) they emit longwave ultraviolet light (most fluorescent minerals respond to shortwave ultraviolet); and, 2) they emit a significant amount of visible light which interferes with accurate observation, but is not a problem for novelty use.
