[Help Me] UV light for rocks (minerals) verification

Price Range: Under 50$

Purpose: Checking my minerals/specimens like fluorite

Battery Type & Quantity: doesn't matter. It can be AA/AAA or be charged from USB

Size: I'm not sure, but the smaller is better.

Type: handheld

Main Use: I'm mining some minerals in the mines by myself but I'm still not experienced enough to know what I have. I have some fluorites in my collection but don't have UV light to check it.

Switch Type: Doesn't matter

Anything Else?: I had 395nm UV light but looks like smaller number is better like 365nm. Also as I understand I should have ZW2B filter?

I'm looking for something from Europe. I'm from Poland
