If you can get it to work like tritium, you might be onto something. Other than that, I dont see it really going anywhere.
I can pick up any of my tritium equipped guns and the dots glow bright, 24/7/365, with no other light source. Thats pretty tough to beat.
That $80 initial outlay, works out to roughly $6-8 a year too, so its really not a bad deal.
