4 AA batteries would make the light a little larger, but I would use this light almost exclusively. The ultra bright, white light is amazing. You really notice the difference when you are trailing. We were looking for blood sign last week. The other two guys had two flashlights each and missed several spots the deer left. I found several spots they had walked by. The other flashlights just did not measure up.
Pros: Excellent for trailing or looking for something dropped or lost
Cons: Expensive batteries with relatively short life (2 or 3 hours)
