Have various brands of flashlights around the house and in our cars. Found all of these were undependable for walking to and from a tree stand in the dark. So about 20 years ago I paid big big bucks (for me anyway) and bought a Surefire 6P. Money well spent. Never failed me and I still have and use it. 6P takes 123 batteries which are a little hard to find around here and a little expensive. And I wanted something more powerful, rechargeable, better battery life, and smaller for pocket carry. The 6P is only 65 Lumens and 123 the battery life about an hour. About a month ago I purchased a flashlight less than half the size of the 6P that is rechargeable from the USB port in my car. Battery life was increased 4x and has 1600 Lumens verses the 6P's 65 Lumens. For about the same money I paid for the 6P years ago. And it will power itself down if it gets too hot. Flashlights are pretty impressive these days if you have been living under a rock like me.
