Hi all,
EDIT to add runtime graphs
I just finished my Jet-I runtime tests. The light was tested with different Li-Ion cells (AW's and old TrustFires) and different NiMH cells (LSD Eneloop and non-LSD high capacity Sanyo 2700):

The regulation of this light is really impressive. It looks like the efficacy is the same for all the output settings. The Jet-I is also able to deliver the advertised 45 minutes on high with an AW's cell and 126 minutes with a high capacity NiMH cell - 80% more than the 70 minutes given in the specification.
Note that with NiMHs the Med mode ("50%") brightness is around 70% of the High ("100%") brightness - no wonder that the difference is really hard to see. With Li-Ions the percentage names are much closer to the real output differences.
I also made the locator (beacon) mode test. After 61 hours I turned the light off, took out the Eneloop and discharged it. The battery had 1540mAh left. It is only an approximation but the Jet-I in the locator mode should thus run on an Eneloop at least 10-12 days. Quite nice
END EDIT
Today I received the (pictorial) description of changes in the new Jetbeam Jet-I v3.0. I think it wasn't posted yet. The most important:





and the summary:

The lights should be available with R2 and Q3 5A and with both OP and SMO reflectors.
Sounds good, doesn't it?
The full set of pictures is available here.
