I picked up a Xeccon Spiker 1211 last fall to pair with my Light and Motion Taz. Xeccon lighthead goes on my helmet, battery pack in my pack. The lighthead which I think is a great feature. It's kind of a floody spot, but they do sell others that are more contained and have a longer throw. It does work nicely with the Taz which has a very wide and even beam for the bars. Xeccon uses good quality Samsung and Panasonic batteries in good quality cases. Their site is here

The guy from the site that posts on mtbr is very helpful in answering questions if you need help choosing which model to go with.
