I bought a bunch of crayons and decided to experiment with some different LED colors I’ve got. In these photos I use:
SST 20 deep red
W1 Blue
W1 green
A UV emitter I have
Nicha 219b 2700k
W2 6000k (I think)
Unfortunately I can’t seem to post multiple images here on Lemme, but I created an Imgur post.
Nice test I was surprised with how bright some of it glowed in UV!
