It does not say anywhere on the site and I believe that both 3W and 1W lights can and often do use the 14500 cell.....I am no expert in electronics so it is not clear to me.

the cree die is actually both - it can be run at 1W or 3W with similar efficiency (from my understanding)

with an AA (1.2-1.7V) battery it will most likely be running close to 350ma @ 3ish volts - or 1 watt, whereas with the 14500 (3.7-4.2V) battery it will (hopefully) be pushing all 3W (750MA @ higher vf (or something like it)) to the LED
