FLORESCENT ROCKS

Now that you mention it, I think I read that somewhere, plus some birds and insects are sensitive to detecting certain wave lengths of flowers for food purposes. Not sure but I think hummingbirds were mentioned as some of these. Makes sense if true.

Nice collection!!!

I bought two UV-Beast lights, the V3 that you have, and the Mini-Beast 365nm. 

The big beast has way to much visible light, but it's still pretty decent, especially for scorpion hunting, as it'll light those buggers up at a very long distance, minerals for that matter too!!!

The Mini-Beast is pretty good, still lots of visible light, but at 365nm, it really does a great job of fluorescing minerals without the visible light overpowering the fluorescence nearly as much as the UV-Beast V3 does. A good UV-pass filter for the V3 would help greatly in that regard.



I'll try to upload some comparison shots later.  

Fluorescent photos are the bane of my existence!   It's impossible (for me anyway) to get a good shot of what I see, and virtually impossible if you're using your phone's camera.  

This photo is from the UV-Beast V3

I do see purple, but I can also see orange stripes on the piece on the right.  

This is from the Mini-Beast 365nm.

You can see the orange in the middle rock, which is washed out from the big Beast.  The difference between the two lights looks much closer in person, and there is not as nearly as much visible light as my Galaxy S23 Ultra makes it look like.  

To really capture UV photos well, you need a good visible light blocking filter on the light source (mini has a cheap one, the big one is unfiltered), a good UV blocking filter on the camera, and a pitch black room.   When I say "good"... it's $800 for the 52mm narrow-pass filter to fit the UV-Beast, & $400 for the 37mm UV blocking filter for my Olympus OM-D E-M10... so for now I'll just stick with the cheap UV bandpass filter & $15 UV blocking filter which I'm not able to find right now 

Here's a more accurate representation of the difference between the two beasts:  This is much closer to what my eyes see.

UV-Beast V3 385nm-395nm:  I see there is a second version of this light which adds a UV Pass Filter & is labeled as 365nm...
 


And the Mini-Beast 365nm:



The big beast illuminates those sub-surface UV reactive elements, but the visible light from it makes it hard to see.  Whereas the mini-beast clearly illuminates them.

I can't say how happy I am with them and I've already blown the minds of a bunch of people by dragging them downstairs and lighting the place up.

I actually have to warn parents of young kids to be ready to restrain them from going berserk when I switch on the light. Literal pandemonium breaks loose with the kids yelling and jumping up and down, twirling like a Whirling Dervish, yelling gibberish, and I'm not even kidding a little bit.
.
Even old people are doing the oohs and ahhs or standing there mute in amazement at the light show. Even I will go down there and just stand there gawking in awe of nature.

Rocks that continue to glow after the UV light has been taken away are called phosphorescent in addition to being fluorescent. I only have two that do that.

I found that I have to keep the area clean and free of dust so that it's glowing does not take away from the display. It sure makes it obvious about the state of cleanliness of the area.

Warning... don't ever shine the light in a public restroom or you'll be traumatized forever.

LOL - twirling like a whirling dervish - I haven't heard that in a coons age!

OMG Randy, you're too much fun..

Just don't get carried away and start pulling in strangers off the street.

Thanks for the info on phosphorescent. I learned something new! I was calling them radioactive before I knew what it was.
