Hi all,
I've had this light for the last 1.5 months (roughly). Since I don't usually follow the Inova lights (my other Inova is an original design X5), I just assumed this was the T2.
There were 4 at the store when I purchased mine at a cost of roughly $15. I tried them all and chose the one with the least amount of blue tint. It came with 2x Duracell CR123a's pre-installed so it can be tested in-package in the store.
The loading is the same reverse-battery direction as my X5. The light has a decent throw and is bright, but definitely a Lux-I. With fresh batteries in both, the Inova seemed slightly brighter than my SF E1e.
I didn't realize that this was a new style or I would have posted something sooner.

EDIT:
I forgot to mention that it does, in fact, have the Fresnel looking Tiros optic.
