Alright,
Sorry to take so long to get pictures up, but work this afternoon was not cooperating with flashlight priorities. oh well, anyway, as for 18650s, they will not fit in the light. I tried a 17670 on high, and there is an almost immediate step down in brightness. I do not have a way to measure the output. Also, the selector ring has notches, or clicks for the outputs, it is not smooth like the original. Here are some pictures of the items, and the UM2 next to a P2X, and some with an original U2. Hope you enjoy!
