I don't think the AF is any good, or at least I have not heard good things about it.
The Tritec is great, I too however do not know where or how to source it. :-( I have some C3 that has a green tint to it in daylight.
I have used NoctilUmina in green and blue lumes. The green 12 hour lume has a very close to pure white color to it in daylight. The blue lume has a slight green tint in daylight, but should glow 24 hours according to them.
From what I could tell from tritecs website, it looks like you may be able to order from them, but they do not have an online order form or such. You may have to do it through telephone and snail mail or fax.
I am full up on lume now, so I am not ordering anything soon, but if I was, I would ask my sister-in-law's business (jewelry store) to maybe try to order from TriTec.....
