[Rockhounds] UV flashlights

[Tim Fisher]

That's a good website, but I bought some old medical lights off Ebay because
they were cheaper.

I would recommend getting one with a filter. There are several models
available. Here is one site that sells them.

Also consider a 405 nm Laser. Technically it is above UV.. barely, but the
intense power on the spot elicits some great responses with some minerals.

Pete,

It depends on which one you get.  A lot of the cheaper lights are broadband
and also have a lot of visible blue.  As far as I know they're all UV-A
(longwave) but I'd be happy to be corrected on that if I'm wrong.

Best,

Don
