Panther Vision Powercap LED lighted Structured Hat

I have the beanie hat with LED and I can honestly tell you that the LED’s in this is very bright. I am guessing it is less than 100 lumens however; it has a great beam pattern that is a mixture of flood and spot that will display a very good amount of light in front of you for at least 50 feet or more. I am actually considering purchasing more just to have stashed in my vehicles and extra for my bug out bag, etc.

Are the batteries replaceable?

Answer: Yes, they are.
