This thread is really about lights that can use both AA and 123 not either one.
Yes, but the thread title is actually pretty misleading: "Flashlights that accept 1xCR123A or 1xAA". This is why a number posters assume he's talking about one or the other, when he really means both. To add to the confusion, he does not even specify in the OP that he is only looking for lights that take both AA and CR123 cells. However, it can be deduced from reading his list, which only consists of combo lights with optional extender tubes for AA batteries.
