Re: current light/battery table
Those voltages aren't an indication of what the XM-L can use but rather the limitations of the electronics (the driver). The drivers are configured in different ways depending upon the type and quantity of batteries that are intended to be used with the light.
The length of time a light will run in its highest mode is more a function of battery capacity, drive levels, and the electronics. There is no direct correlation with the total voltage. As an example, if take two otherwise identical lights and power one with 2x16340 lithium-ion batteries and the other with 2x18650 cells, both will have the same operating voltage but the latter will probably provide 4x the runtime.
You should be able to check the manufacturer's specs for a given light to get an idea of runtime but, be advised, these can be a little bit misleading. Before purchasing a light, use the search box in the upper left corner of any CPF page to see if there has been any discussion here of actual runtime (often found in reviews).
