I found a cool rock!
There doesn't seem to be anything like #rockstodon or #mineralsodon so I'm gonna go with #askfedi and beg for boosts:
I would like to build a small thingy to display UV-active minerals, and I wanted to use LEDs rather than tubes for a number of reasons.
Does anybody know if there are LEDs in all three useful bands (UV-A, UV-B and UV-C) and if they are any good? That is, is my project even possible or is it doomed from the beginning?
Itβs a wavy rock.
