I also thought the Eagltacs were direct drive on Li-ion cells?

Re: Some recent small 1xAA lights
I have the regular 2012 edition, so can't say for sure, but another poster wrote that the 2013 Ti D25A retains low, med and high on 14500, but with higher output through all modes.
From ET:
Using 4.2V li-ion direct drives the LED and yields maximum output at the expense of extensive heat generated from the LED. Limit each usage to less than fives minutes (or less than one minute each with freshly charged li-ion for the first couple times). Active cooling (blowing cool air toward the light) or passive cooling (holding the light in your hand) helps preventing excessive heat built at the LED. Turn off the light to allow it to cool down if you find the flashlight too hot to hold. Do not leave the light running unintended with li-ion. During direct drive, output at low and medium mode will be higher than normal. (My emphasis. Seems to imply some regulation.)
