The L2D is pretty outdated now, but there's another thing to think about that hasn't been mentioned yet. And that's the benefit of using a common battery like the AA. I wouldn't want to go back to only using the AA to power my lights, but after living through a 3 day power outage last year I was glad to be able to swap batteries in some of my lights while not having to worry about recharging batteries. So my answer would be to by more lights, but make sure you end up with at least 1 that uses AAs.
