I've recently become interested in glowing minerals and a site said that a black light wouldn't bring out the colors. Can anyone tell me where, and what kind, of mineral light i need to get. I'm looking for versitile(multiple wave lengths), cheap, and portable. I will take a plug in one though. Also if you know a site that tells you how to find flourescent rocks in your state I would appreciate it. Thanks.

Great question! This is a fascinating field for mineral collectors, and I was addicted as a kid when I visited a museum in Jerome, Arizona. There was an entire darkened room full of these, and my parents had to drag me kicking and screaming out of there.....
Your standard blacklight bulb won't work. First off, there are two commonly used types of ultraviolet light used for minerals which are known as longwave and shortwave. I find shortwave to be more effective, where more minerals will glow and will provide a wider range of colors than longwave will.
Longwave is just that, a longer wavelength. Many rocks and minerals will glow, look at a science supply catalog in the mail or on the web, or on Ebay. Do not get the blacklight bulb "party light" or similar bulbs, your results will be very poor.
Shortwave UV is the best option of you want alot of colors and more minerals to glow. This is the same type of UV that causes sunburns, so you will need to use gloves and protection when using shortwave lamps. Many portable lamps come with filters, and even though they are not as effective, it is important to leave these filters on the unit. Shortwave lamps are more expensive, but the portable lamps are still affordable. I would buy a portable lamp, and join or visit a gem club to see if they have a shortwave lamp at the clubhouse. I have a portable lamp that I found on Ebay.
My suggestions: Join a gem club, as there are likely to be members into fluorescent rocks and minerals. Visit some museums with fluorescent mineral exhibits, this can be a load of fun. Most important though, join a gem club. There is nothing more fun than uniting with like-minded people!

Fairly gentle is the lightest color for impartial tones - no red undertones and no golden undertones. Light is the lightest color for golden tones. It is dependent upon your tones, which I are not able to relatively inform, however you truthfully possibly excellent with each. There is a starter package that QVC sells that presents 2 sunglasses of the basis - and Fairly Light and Light are in a single. I advocate you get that and check out it that manner. Then return and get the basis within the colour that's exceptional for you. It comes with Warmth and Mineral Veil and a Brush. They have a 30-day no query go back coverage, and proper now it's 60 days for the vacations.

What you need is a ultra violet light what is filtered to isolate both the long band UV rays nd the short band UV rays. I have a portable light that I purchased several years ago with such a filter over a portion of the bulb....
