Actually there are only two - but they sell the standard ones in packs of one or two - hence the x1, x2 (times one, times two). And their photo of the standards is out of date, showing the now-superceded Original versions.
Traser don`t make the glowrings themselves, though they are the most well known because they are famous for their watches. The packaging of my Glowring-X2 mentions a company called H3 (UK) Limited. I think these are the guys who make them, and they get distributed by loads of places, often under different names. By far the most amusingly named of these distributors is Frug -

:edit: or at least it used to be. Seems like they installed a new e-commerce thingy that isn`t quite ready to work yet.
