Just because they are using a "3-watt LED" doesn't mean that they are driving it at 3 watts. I suspect that it is actually being driven at about 1 to 1.5 watt. A pair of AA alkaline cells would not last any where near 3 hours driving 3 watts.
On the positive side, since the review seems to indicate that there is some sort of voltage regulation circuitry then you might be able to use Lithium AA cells and perhaps double the burn time.
Edit: I see where Flashlightreviews says that the manufacturer specifies only Alkaline cells. That makes the light useless to me.
Edit again: I looked at the first page of the CandlepowerForum link that was posted earlier and I see that the 2 AA light was tested with Lithium cells and got 6 hours of burn time. It still remains though that the manufacturer has said to use only alkaline cells.
