I have found that anything under a 6w bulb is almost usless though. Most of the common, over-the-shelf models are long wave (UV-A). You also need a short wave (UV-C), but this is not for the weak-hearted, because a decent model can cost $200-$500. I found an 8w short wave for $280 that I am happy with. Just check out several of the on-line stores. Hope this helps.... Some rock and minerals will show different intensities or even different colors under different wavelength blacklights.

Long wave UV lights are the relgular black lights that people used for posters in the 70's. Some rocks do glow under these. But short wave UV lights are a little harder to find, and also more expensive. I just ordered a small battery operated shortwave light on eBay for $35 + $5 shipping. Actually it comes with both longwave and shortwave bulbs. Shortwave lights will make many more types of rocks glow than longwave. I just collected a bunch of chalcedony out in Nevada that is supposed to fluoresce, but doesn't under the long wave. So I am hoping it does under the shortwave. The battery operated light may also come in handy while rock hunting. Hi Carl, yes there is a difference between long wave and shortwave UV lights.
