Can i use 2 18650 batteries instead of the 6 aaa?

I don't think so. The flashlight has 2 casings or holders for the 6 batteries and works great 👍.

How much luminous power does it have?

I don’t know the luminous power and the manual does not show. I can say that it is very bright and I can feel my arm warm up when I checked for uv ink on an admission stamp

does it help you do find dog poop outside

Depends on what you feed the dog

How many lumens does this have?

Lumens is a measure of brightness of visible light. As this flashlight emits UV light, it is not a metric used.
