It's the XR-E variant. The Luxeon III model will probably run around 45-60 lumens, closer in brightness to the Inova (with a smaller hotspot if it uses the same optics as the newer Cree, I can't remember if it did or not)

One thing to bear in mind w/ the Task Force 2C - it's fairly heavy, and the batteries rattle around in the body (you can shim it up with some paper) This makes it somewhat difficult to aim w/ something like a Lockblock (mine stayed in place, but it pretty much could only be aimed straight ahead) and it may be prone to flickering if you run it on rough terrain.

However, the head easily unscrews from the body, opening up the opportunity to mod the light into two pieces - a lightweight head unit (needs a back and a mount) and the battery pack. With a little ingenuity, you could set yourself up with a fine bike light for a fraction of the cost of a retail unit of the same brightness.
