I just got the new iBlaast2 in from Nightlighting in NZ today. They say it's the first one to ship with the new LED's (Cree R2 I am assuming). So here is my first impressions of it, but keep in mind that it is Cinco de Mayo and the Patron has been flowing...
Anyway, I have been using a Jetlites Phantom (helmet mount) for two years using a 14.8v Li-ion battery, which I have always preferred to any other light I have seen in person so far, halogen or HID. I haven't really ever run across anyone with a decent LED to compare with. The Jet light is just as nice as you can get with a halogen IMO.
The first impression of the iBlaast2 was that it was bigger than I thought it would be. The lens diameter must be close to if not equal to a MR16 bulb, but then maybe all triple LED lights are. It's bigger than the Jet anyway. But, after measuring the height of the light after mounting it, it was the same as the Jet because of the higher mount of the Jet. My digital scale is out of 9V battery at the moment, but the listed weights are 135 for the iBlaast2 and 70 for the Jet Phantom. I haven't ridden with the iBlaast2 yet, though, so I can't really comment on the difference.
The programming of the iBlaast2 is pretty easy, but requires reading the instructions pretty closely to get the hang of it. Once you do, it all makes sense. The whole procedure took 45 seconds, but was not actually necessary, I just wanted there to be two light levels instead of three and make sure the high setting was the highest possible.
As far as light output, the iBlasst is not only whiter light, but it is decently brighter as well. I always thought the Jet was pretty much the whitest of the halogens, but it looks pretty yellow compared to the iBlaast2. Jet claims 750 lumens from the 25W light and iBlaast2 claims 885 lumens if these LED's are the R2 Cree's. But, maybe they are something more potent, as they waid it was going to be a 1000 lumen light. Either way, it's a noticable difference how much brighter the iBlaast2 is than the Jet Phantom.
The beam patterns are actually quite similar between the two, with the Jet having a sharper peripheral halo than the iBlaast2, which is a gradual fade out.
I took some photos of the two, but they aren't really all that impressive. The thing to remember is that the camera settings were the same, actually the same as in the LED light shootout, except the aperature was 5.6 instead of 4.0. And they are a little out of focus, but I am not an expert night photographer and rember the aforementioned Cinco de Mayo comment... Also take into account that the Jet light is using a fresh 14.8V battery that is actually at 16.75V when photographed, and the iBlaast2 is using a similar battery, but at a lower actual voltage. The difference is, I believe, the Jet can is actually using the 16.75V at the bulb, but dims slightly as the battery gets down to around 13V. I think the iBlasst uses the same voltage at the bulb regardless of battery voltage output.
The telephone post in the first two shots is about 175 ft away.
I'll try to get some better shots another day, but for now, maybe you'll get the idea.
Overall, I am very pleased so far with the light. The build quality is perfect and I will cry when I first scratch it. I'll get some more info after my first ride as well.

EDIT for more information:
Here are some comparison pix of the two.

The adapter on the iBlaast looks like it will solve a problem with mounting lights on a Xen. The Xen has vents down the centerline of the helmet instead of a rib like most do. It has a rib down each side of the vents connected by two bridges. Without the adapter, you would need to mount the iBlaast on one of those two bridges. The Jet mount always felt to far forward on the Xen to me...the vents on it just aren't really condusive to mounting a light that uses straps. I'm not sure if the adapter will be necessary yet, it depends if the light will be aimed right on the bridges on the Xen.
