These are quite fun to play with, but be aware that there are two different technologies. The older Zinc Sulphide version and the newer Strontium Aluminate version that is brighter and holds the glow for much longer too.
When you buy a multipack like the two in the picture above then you will generally get just one pack of the new high output Strontium based powder and the rest of the packs will be old-skool Zinc based pigments.
I filmed this with the CAT S61 because for some reason the Moto G7 was showing a really bright picture of the glowing pigments until I started recording and then it was very dim. The glitching in the video is what happens when you use other camera apps with the CAT S61.
I included a search link in the YouTube description.
