Magicshine clone lights - XM-L

I've got a couple of these Magicshine clone lights. The both have an XM-L led emitter but the controllers are a little different.

Light one has high, low and strobe. Light two has high, medium and low.

Both lights on high draw 1A from a 7.4V supply.

Current draw

Function	Light 1	Light 2
High	1A	1A
Medium	N/A	0.5A
Low	0.2A	0.2A
Strobe	0.5A	N/A

A battery pack made from 2 of the new 3400mAh panasonic cells should power these lights on high for almost three hours.
