A cool birthday gift from my husband! I collect minerals and have been after UV reactive ones lately. I had a cheap dual wave UV light that likes to die, so he got me a more powerful longwave UV flashlight. It really makes most of the rocks glow and as a bonus, seems to charge up my glow-in-the-dark stuff real fast!
