Hey Bob ,
This is an issue I looked into a few years ago. Glow Nation is "phosphorescent" glow in the dark pigments and Glow.Inc. is " Alkaline Rare Earth Metal Silicate-Aluminate Oxide Europium Doped". I have tried both and Glow,Inc is far superior of any of the glow pigment on the market today. I do not use it commercially so I am willing to pay a little more for the glow. I just use it on jig heads so a little goes a long way. The Ultra Green v10 Glow in the Dark Powder is what I use.
Ultra Green v10 Glow in the Dark Powder - Hope I am not stepping on your toes Bob, just trying to share what I do.
Life is Good !
