:shrug: It depends on what a "Lithium AAA" is to you I guess.
Bottom line: The light runs on 1.5V cells.
The means your typical NiMH, NiCd, Alkalines, Lithium Primaries, and various other standard size and standard voltage cells will work just fine. I was not even aware until just recently that someone was foolhardy enough to create a AAA cell with a 4.2V cell voltage, which will destroy almost any electronic device AAAs are intended to be used for.
I am disinclined to repeat what I've said before about cells that are improperly designed for their intended applications, and refer to a post I've written before on the topic here:

If you all wish to continue the discussion of that sort of topic, feel free to do so on the weblog linked above, or in another thread.
Fallingwater: The LEDs I'm using are 24000mcd at 20mA. The Nichia GS is 30,000mcd at 20mA. The Nichia part cannot, in my opinion, be considered a white LED and is
very blue even at just 20mA. The parts I'm using are actually white, I'm not overdriving the LED at 2-3x the rated maximum current (which does kill the LED over time), and the driver I designed has efficiencies in the upper 80s, which results in happy LEDs, happy batteries, and a rather long runtime, which was the primary objective behind the Mako.
Mr. Blue: It's looking like late February or March right now.
Take care folks.
