All I really know is some rocks fluoresce at the 385-395 wavelength, but more do at 365nm.

WARNING: Be careful if you get a 365 ("short wave") because that's the one that will "microwave" your eyeballs. Serious damage is possible.

Outside of that, turn off the room lights and shine your UV on the rocks. I think most long-wave UV lights also produce some visible light.

I just went through this... there is just too much info out there. Seems like the fluorescent minerals groups have a couple rundowns, and yes 365nm seems to fluoresce much more, also you want a filter that blocks the visible light. Seems like everyone says the Convoy S2+ and the S8 are best/moderate priced options, but some patent troll apparently keeps them from being imported at the reasonable price the rest of the world pays. I ended up with the Alonefire sv44 because the specs & price on Amazon seemed good I think their sv003/sv005 are the near equivalent of the convoy s2+ ? Heck, now I see amazon even added a 10% off coupon, $35 shipped.

I can't really speak from experience, have a plugin science lab UV light, but wanted one to wander around outside this summer. Thought my rocks had lots of fluorescent speckles, till I realized that was dust... 2c

I've a Darkbeam UV395 mini flashlight and it works ok. Kinda useless during the day for large area scanning, but does ok when you can block most light. Lots of fun to use at night or in caves. Battery life is ok, about 4 hours, but again it's palm sized.

The Convoy S2 is a bit nicer because it is a tad smaller, waterproof and a touch brighter, but $20 more expensive.

That is way cool, may have to get one of those for myself!

Thanks for the link!

Edit - Thanks for that, oregon. I'll do more research before spending my hard earned cash.

Yeah, I think this is the company with the patent issues. There are enough passionate UV lamp folks and fluorescent mineral folks crying foul that something seems amiss here to me, so I gave this company a pass, ymmv.

amygdule: $20 for a Pastrami Sandwich Nov 9, 2024 23:11:01 GMT -5

RickB: Cheaper by the dozen? Nov 10, 2024 7:07:13 GMT -5 *

rocknrob: That had better be a good sandwich for that price, otherwise you're better off making one yourself. Nov 10, 2024 21:10:43 GMT -5

amygdule: I like my sandwich made by a talented artist that deserves a Tip...Thank You Nov 11, 2024 7:12:10 GMT -5 *

RickB:

rocknrob: I make my own sandwiches and yet I never tip myself... OMG I'm the a@@hole! Nov 11, 2024 11:29:51 GMT -5

amygdule: Her sandwich taste better... Nov 11, 2024 17:07:29 GMT -5 *

rocknrob: There was a shop in Portland, don't know if it's still there called Kenny and Zukes who made the absolute best pastrami sandwiches I have ever had. The problem is every restaurant thinks their sandwich is worth $20 now and seldom makes the grade. Nov 12, 2024 9:53:31 GMT -5

rocknrob: So, to end my thread on sandwiches. If you find your sandwich worthy of that price by all means keep going to that restaurant (chewie)
