I took some pictures and I couldn't really tell if there was a difference, I kind of thought the aa were brighter but I'm such a novice at this that I couldn't really trust my observation. I do know that the only reason I would use the aa version would be for extended rechargeable nimh battery useage. I love the small form with the lithium battery with the click or twistie version of the tailpack.
