Going in order counterclockwise from the largest one being 365nm, I have 340, 320, 310, 295, 275, and 255. The second image is clockwise except 320 and 310 are swapped, idk.

My camera doesn't like all the color, but the scheelite glows red in 295 and 310, purple in 275, and the classic cyan in 255.

The second image is a piece of terlingua-like calcite that has extremely strong reactions compared to the cheap stuff you can buy in bulk. It goes from yellowish with blue phosphorescence in 255 and 275 to purple in 295, white in 310, back to yellow in 320, bright yellow in 340, and finally magenta in 365. That piece also has some kind of white light fluorescence that makes it have a green tint with a very close and strong white light.

There's still more LEDs inbetween wavelengths that I'll have to look out for in flashlights, I don't have a solderer for LEDs. There's 222/230nm, 265nm and 280nm, something around 350nm would be nice too.

295nm is my favorite. It has the most reaction. Thank you!

The 719a couldn't give a good spot profile, op had a lumpy spot, 20°-45° tirs had star like beams. I had some diffusing film from broken screens so I cut a circle and found the 20° tir gave the best projection on the film. The distance from the shed is about 50ft, it's pretty useable. The cri is great too, I could see a roach bright as day in dead leaves, I can post that too.

This is my first real post so it's a bit messy lol.
