or my math is not working.

Looking at an Eveready Hardcase LED flashlight. It uses 2 AA batteries ( series ). Has 3 led bulbs, which is says are one watt each. They claim a run time of 17 hours. I understand that a AA battery has a capcity in the range of 2700 to 4000 maH depending on type and grade. This does not seem to add up to running 3 watts for 17 hours! Are the LED bulbs really one watt each, or does that mean the "equivalent light" of a regular one watt bulb??
