The next headlamp

I'm probably going to go with Cree XR-E's, Q5 bin ... I'm torn as to whether I should run at 500 mA or 1000mA. These LEDs seem pretty amazing:

107 lumens at 350 mA
171 lumens at 500 mA
214 lumens at 1000 mA

compare that to my Luxeon I Stars:

45 lumens at 350 mA

At least on paper, thats waaaaay more efficient!

I also learned that "JB weld" is a good way to attach the star boards to the heat sink. Now I just have to round up another one of those!
