Well you know I wanted a quality high performance light that has a comnpany that stands behind it's products. It cost a full 2 weeks pay for me but thats ok. Will I spend more on a light? Probably not. When I go to use it I understand why its so costly.
The batteries are in tubes that thread on. I have 2 small ones and a medium sized one. Will probably add the full size at some point. Someone long ago here had one. It is an old light that is maintained and kept up to spec by Lupine. I prefer this than constant new designs that you can't expect to get parts for.
My other light of this class is a Led Lenser X21R. That is another German light that has been around a minute. These are great for illuminating large areas.
