Fluorescent OK Geode 4

[KStateKing]

I wasn't lying when I said I had thousands of these...
I am curious on this one, which is under a Long wave lamp. This may be a dumb question, but is this actually fluorescent, or is it simply reflecting the color of the bulb? It doesn't really do much under Short wave.

does your uv light have a bandpass filter?

A what? I have no clue what that is...

I'm sorry, a bandpass filter eliminates a good deal of the visible light from the UV source but allows all of the UV wavelengths through equaling less reflected visible light (blue) back. My Light has one installed (convoy s2) so I wasn't sure if you were using the same.

Just got one of those convoy lights and installed the filter. To answer my own question above, that rock is mostly reflecting the purple bulb of my cheap 22 yr old blacklight. LOVE this little convoy flashlight though!
